Rainbow Cake in a Jar
I’ve always had a penchant for sunshine in a jar. Doesn’t the very phrase itself, “sunshine in a jar,” roll off your tongue and fill your mouth with magic? While I’ve never yet found myself a sunshine in a jar, I think we may have just concocted it in our kitchen tonight. In this simple recipe, a basic white cake is turned into a slew of bright colors, baked to perfection, then topped with a creamy white frosting.
Cakes baked in jars can be topped with traditional metal canning lids and stored in the fridge for up to five days. They make a great treat to ship to someone, so long as you can ensure delivery to it’s final destination within 3 days. Of course, you don’t have to do anything special with your cake-in-a-jar. There’s something lively & different about serving personal-sized batched of cake in glass mason jars. They make for great dinner party conversations and ever better after-school suprises for your kiddos. Especially this one. Because, who doesn’t love sunshine in a jar?
- 1 box white cake mix made according to package instructions
- Neon food coloring in pink, yellow, green, turquoise, and purple
- 3 one-pint canning jars
- 1 can vanilla frosting
- Rainbow sprinkles
Preheat oven to 350 degrees. Thoroughly wash and dry the inside of each canning jar. Spray the inside of each jar thoroughly with nonstick cooking spray. Set aside.
Scoop about 1/2 cups of cake batter into five small bowls. It doesn’t have to be perfect, don’t panic if you get a little more of less of one color than another. Tint each bowl of cake batter with the food coloring until very vibrant.
Spoon about 3 tablespoons of the purple batter into the bottom of each jar. Spoon equal amounts of turquoise batter, then green, yellow, and pink. Place the jars in a shallow baking dish, add about 1/4″ in water in the baking dish. Place the baking dish in the oven and bake for 30-35 minutes.
Remove jars and allow to cool completely before scooping a small portion from the top of your cake and adding a hefty dollop of vanilla buttercream to the top. Sprinkle & serve, or cover with a lid and store in the fridge or pop into the mail & surprise someone you love!
POST EDIT: Several commenters have indicated that the cake is not cooking all the way through in the 30-35 minutes indicated in the recipe. This was enough time for our cake, but I’m cooking at high altitudes, and my oven tends to bake hot. So, I’d recommend baking the cake for 40 minutes, then return it to the oven if it still doesn’t spring back to the touch when you check to see if it’s finished. As for the cake puffing up and out of it’s bottle, ours did that a bit, as well. Easy fix. We just scooped a bit of the cake out to make room for the frosting and wiped the outside of our jars clean. Several people have indicated that the wide-mouthed mason jars work a little better for this purpose. I’ve not yet baked with wide-mouthed. What you see above is what was baked in my kitchen according to the recipe instructions, and what came out of the oven when it was all. Of course, if you’re feeling wildly impatient, you can also zap the cake in the microwave for 2 minutes. It’s going to bubble up, for sure, but you can scoop the top part of that cake out, frost it, and no one will ever be the wiser. Good luck, everyone! This is such a fun cake. My kids went nuts over it, and I hope it works as beautifully for you as it did for us!

sheila commented on Apr 08 11 at 11:46 pmI love this idea. I’m going to try it in baby food jars for my sons 1st bd coming up. A mini cake for everyone!
Cammie commented on Apr 11 11 at 8:44 amI have made other types of cake in a jar. Some can keep for months if properly stored. This cake would be really cool if it was done in the wide mouth quart canning jars, because then you can pop it out and the slices would be so cool. Thanks for a great idea..
Michelle commented on Apr 11 11 at 10:32 amWhat a fun idea!! Love it!!
Thank you so much for sharing this!

Bright Shadows commented on Apr 11 11 at 1:01 pmThat looks so pretty, I love how you can see the colours right away. And if you don’t finish it you can put a lid on the jar and take it to go! Awesome.
Jael Cain commented on Apr 11 11 at 2:01 pmLove it will definetly try this

Ninah from wechooseorganic.com commented on Apr 13 11 at 4:40 pmAt ELENA:
Exactly, thats what I was thinking. Because today I kept a glass of joghurt instead of throwing it away and I wanted to try the cake in a jar as well.
I dont know whether I can use normal, ordinary glasses/jars from the supermarket that had joghurt or other stuff in them…
Does anybody know??Just baked sugar cookies and coka cola cupcakes…they are soooo delicious!!
Will post the recipes on http://www.wechooseorganic.com in a couple days.Greetings everyone

Kate commented on Apr 13 11 at 5:47 pmLove, love love!!!!! My kids will go nuts over these! :)
Lauren commented on Apr 14 11 at 7:21 am@ Elena
the jars should be able to withstand the heat in the oven as they shouldve been annealed in a lehr previous to them going on sale, also the placing them in a tin of water helps
Kim commented on Apr 14 11 at 10:35 amAwesomeness!!!
Katie commented on Apr 14 11 at 1:02 pmThis is probably the most adorable thing I’ve ever seen. My friend and I have started this tradition where we send treats back and forth in the mail (she’s in Pensacola and I’m in Orlando) just as a Thinking of You! type thing. In the last box I got she had put mini cupcakes inside mini mason jars and I’ve been stumped with what to send back because I’m worried about the Florida heat. But this is perfect (sans icing)! I’m super excited to hear about her reaction when she opens the box and finds these beauties. Thanks for the great idea! <3
J commented on Apr 14 11 at 9:11 pmYou don’t get colors as vibrant as those from food coloring? Are you sure your didn’t use food color gel? Please clarify.
ELBSeattle commented on Apr 15 11 at 12:52 amThat looks revolting.

Cookie Monster commented on Apr 15 11 at 9:18 pmThese are awesome! I already have so many ideas for holidays….green & red alternating color cake for xmas…..black & orange for halloween..etc.
@ J…. it’s NEON food coloring which is more vibrant than just regular ol’ food coloring. :)

L commented on Apr 17 11 at 2:20 amSUPER cute idea. My 11 year old daughter and I used this as our “Girl’s Night In” recipe and had SO much fun! We just made these tonight and ran into a few problems. The cakes were “runny” in the middle…not completely cooked through and once they cooled they shrunk terribly as someone else had mentioned.
For filling the jars, we found that using an ice cream scoop cut down on getting the sides “messy” and spinning the jars a few times helped to level the layers out nicely.
Barbara commented on Apr 17 11 at 3:24 pmI ran into the same problems. The first batch came out severely undercooked and then shrank a lot. The next batch I bumped the heat up about 10 degrees, and baked them for 40 minutes, and they STILL came out undercooked and while they were baking the cake batter ERUPTED out of the mason jars. I am so disappointed :( Any tips so my NEXT attempt doesn’t fail?
Lauren commented on Apr 17 11 at 9:02 pm@Bee and @Elena I would stick with canning jars for anything baked, as the glass is tempered to withstand higher temperatures than normal. Food storage jars off the grocery store shelf may shatter in your oven. That said, I’ve done pies in the 4 oz wide mouth jars, and they were adorable- a bigger hit with the adults than with the kids. I think it’s the portion control factor that made the small jars so attractive.
vedette commented on Apr 19 11 at 11:27 amI tried making one of these awhile ago and it shrank drastically when I placed it on my jar, what am I doing wrong?
Jane commented on Apr 19 11 at 2:46 pmI recently discovered mason jars and am obsessed! I can’t wait to try this out it looks yummy, I’m now always looking up new ways to use them lol

sam commented on Apr 20 11 at 12:50 amI just made these and am not sure how to post my pics. I used regular jars off the grocery store shelf. If following the instructions of putting water in the baking dish you should be fine with any type of glass jar. Mine came out 70′s looking dark on the outside but as soon as you take a piece off the top the inside is really cool. I made them because I’m headed to the beach for 5 days and while there have a niece celebrating her 9th so this is absolutely perfect. Put a lid on and they travel. I know I didn’t layer the mix correctly as it didn’t look close to the picture but it is ok. The inside is bright and swirly with colors. I’ll try to post pics and thanks so much to whoever was the original poster.
CK Bakery Shop commented on Apr 20 11 at 12:36 pmWe at http://www.ckbakeryshop.com do something close. It is our “Stars N Stripes” cake. We swirl the batter. Our Facebook page has pictures of it. This is a really cute recipe. Thanks for sharing!!

ANGRY GOD commented on Apr 22 11 at 2:43 pmIt´s pathetic
Candi commented on Apr 23 11 at 9:39 amMine are not quite like the pictures :(
They are darker and they shrunk… Any help? These were the trial runs so I need to perfect them for end of year teacher gifts. Thanks!
Z commented on Apr 23 11 at 8:29 pmThe colours of my cake definitely did not turn out like the picture. They came out a little brown, but that’s to be expected.
lisa commented on Apr 24 11 at 4:53 pmisnt there a recipe for the cake? I cant get cake mixes like that here in germany, and I would rather make it myself, would ordinary sponge cake work? Awsome idea, cant wait to try it out.
haylea commented on Apr 24 11 at 10:34 pmI made these last night but they didn’t turn out as pretty, they browned all over the sides. Could it have been because i used vanilla cake mix instead of white? I’ll be trying again tonight because it’s such a wonderful idea.
Rita commented on Apr 25 11 at 9:59 pmSuper cute idea, and I attempted to make a few tonight, BUT…how do you get them to come out so “pretty”? Like others have stated, the sides browned a bit and the colors are not as crisp as the picture…the colors are definitely vibrant once cut into. I sprayed the jars before pouring the batter, and the jars were placed in a water-bath while in the oven. Any suggestions? Would really like to try them again, but with better results. :)
Sarah commented on Apr 26 11 at 2:54 pmJust tried my first batch…..the colors ran horribly when I tried to “layer” them. The cake mix was way too runny. I added corn starch and flour to each color, and the consistency was MUCH better for layering. I would def recommend doing this!
jen @ onecurlyfry commented on Apr 26 11 at 3:31 pmI love love love cake! What a cute idea. I’ll have to give it a shot!
Kris commented on Apr 27 11 at 2:01 pmWho on earth would like to eat such thing. Looks radioactive!
Leah commented on Apr 28 11 at 8:35 amI want to send one in the mail to my friend across the country, but I’m worried that it might mold :/ how long do they last and still taste good? It would need to survive over 6 days in the post.
jennibell commented on May 01 11 at 11:17 pmAWESOME! Thank you for the great spring/summer idea ;)
Meli commented on May 03 11 at 5:31 pmI cannot get over these. They are sooooo beautiful. I just wanna stare at them.
Heidi commented on May 04 11 at 1:10 amI made these as instructed. They baked up really thoroughly and I thought I was in the clear. However, once they had cooled the condensation from the cooling process moistened some of the batter at the bottom of the jar quite drastically, to the point where I can’t give these as gifts in the morning. I know they were cooked through because while one was still warm I couldn’t help myself and had to dig in! :) It was cooked all the way to the bottom. Also, they shrank quite dramatically. After an hour I thought they were cool and they had shrunk slightly; however, by the time I went back to frost them – several hours later – they had shrunk more.
I used the gel food coloring to keep the colors vibrant. I found that even though I assembled the batter in a layered fashion the cakes ended up all mixed up – which was fine; it was cute, too. Just not as pictured.
If I were doing this over again I’d buy the wide-mouth jars. When they came out of the oven I’d attempt to pop them out of the jars to cool. Once they had cooled I’d put them back in the jars. I think this might help with the batter problems I seemed to have, and possibly the shrinking issues.
Peechee commented on May 06 11 at 9:35 amI also would like to know how long these would stay fresh if it was sent in the mail? Will it be ok 6 days later in the mail as Leah above had questioned?
Should it be first put in the refrigerator before mailing or just get it to room temp after baking and then put the cover on and then ship out?
Please help. I love this idea and would love to create and send this out for all the dad’s I know for father’s day.
Brooke McLay commented on May 06 11 at 9:38 amUp to three days, Peechee. You’ll want to expedite them in the mail to ensure the utmost freshness.
CatyDid commented on May 07 11 at 3:59 amI tried this tonight for my friend’s birthday. My local grocer doesn’t carry neon food dye, so I anticipated my colors to be a bit darker than pictured here. I used a larger jar than suggested, so I cooked it a few minutes longer. The outsides did indeed brown a little, so the colors appear even darker. But when I scooped the top off to make room for the icing, the inside was surprisingly bright! All in all I am very satisfied with this idea. My gratitude to Brooke Mclay for sharing this grand idea!
Andrea commented on May 10 11 at 2:31 pmOMGoodness….the jars are in the oven and they are looking AWESOME! I live in southern LA, below sea level (lol)…so I definitely had to go with the 40 minutes! My son is giving this to his teacher with a note attached saying “You take the cake!”…thanks so much for this idea!
newbie commented on May 11 11 at 12:41 amThese are quite cool and fun to make, did them for a friends birthday. Thanks for the idea. However, they turn out much much darker then expected, and not nearly as neatly layered as the ones in the picture.

Melinda commented on May 11 11 at 11:39 pmThese were an amazing idea! Although, I did have a little bit of a problem when putting in the batter. How do you put the batter so the colors so blend so much?
Laura Flowers commented on May 12 11 at 3:59 pmBrooke you are the coolest mom ever. I love all your colorful ideas!

PJ commented on May 14 11 at 2:05 amI am thinking about making these for my daughter’s 14th bday party. Can someone please tell me about how many one batch of cake makes??
jason commented on May 14 11 at 2:39 pmthis DID NOT work for me at all!): i was so excited. i’ve attempted it about 4 times now and it’s just not working! i am sad!
becky commented on May 14 11 at 4:44 pmMine came out browned too – and HUGE – and the colors mixed together. I’m going to try again, adding the flour and corn starch to make it thicker, then I’m going to cook in the microwave to avoid browning. Or I’ll cook at a slightly lower temp; my oven runs hot.
Lynette commented on May 14 11 at 5:04 pmIf you leave the frosting off and put the lids before the cake cools they will seal and will be good for months and can be mailed to our troops over seas.
Lisa Dawn commented on May 14 11 at 10:51 pmI tried this today with an 8 oz jar. I only made one jar’s worth since I had a cake recipe that made 2 servings of cake (which was the perfect amount for one 8 oz jar). While the colors may not have been as brilliant as the pictures above, they were definitely very vivid. My main problem was with the layering of the colors. I had blue on the bottom, then pink, then purple, then green. When it cooked, the blue and green dominated but once you started eating it, there were swirls of pink and purple on the inside. I think the 8oz jars work perfect for this. I filled them a little less than half way, and the cake rose to about a 1/4 inch from the top. I’ll be making 6 of these on Thursday for a friends birthday, so we’ll see if I can figure the layering thing out better.
Heather commented on May 15 11 at 5:52 pmOk so I made these today and for some reason my green on the bottom shows more than the other colors… Idk why but gonna try again next week but gonna layer them different….. I think I am gonna put the batter in to bags and squeeze in several different layers.. Green purple blue pink repeat… Will let ya know…..
Tara commented on May 17 11 at 1:46 amCan You use a baby food jar
Melanie commented on May 17 11 at 4:03 pmI made this today with short and fat 16 oz jars; one box of white cake mix made three jars. I baked each jar separately to make sure they were evenly baked.
The first time, the colors were very dark and the bottom of the cake mix did not bake all the way.
The second time, the colors were a little better because I added more dye but the cake then boiled over the top making a mess.
The third time I used a lot more neon dye and the pink was gorgeous when it came out.
I don’t know if it would work for every color, but using more dye made the colors more vivid. However, they still were a little brown and I did not like how they looked.
I don’t know what I was doing wrong but my colors definitely did not turn out like the picture. I think from now on I will be making rainbow cupcakes instead. So this was not a total waste! Good idea though, looks so cute if it is done right.
Amber commented on May 18 11 at 7:40 pmI was so excited to do this until I started reading the reviews. Now I’m scared to try it! Maybe I will any how ;)
mercedes commented on May 21 11 at 11:14 amsorry you didn’t mention anything about the glass. i once happened to cook something inside a glass recipient in the oven and it wasn’t heat proof so it broke. does it have to be heat proof glass or it worked just fine for you with regular jars?
שף בבית commented on May 24 11 at 8:41 ami love all the bright colors. i also posted a few similar things at my site : http://www.chefbabait.com/ . loving the original idea. great post.

Chelsea j. commented on Jun 01 11 at 1:43 pmI did a practice set of these today for my daughters tie dye party. I used 6 half pint jars instead of 3 pint jars. They turned out so cute! I had no problems with them at all. I used the neon dye. They erupted over the sides, as to be expected, but cleaned them up and they are adorable! I also swirled the jar around each time I put a new color, to make sure each color shows. Sine they were smaller,
Chelsea j. commented on Jun 01 11 at 1:44 pmOops I meant since they were smaller I baked for 16 mins to start, put them back in for 5, then 3 more, for a total of 24 mins. Seemed to do the trick! Thanks soo much for sharing!
Joanna commented on Jun 07 11 at 3:25 pmA little late to the game I see, but my little man and I just finished our first batch of these and they are BEAUTIFUL! So they did brown a little (cake does that, weird!) and I left too much room in the jars, so… extra frosting! They’re not perfect, but since the delighted taste testers of my practice runs are 7 and 4, NO complaints until I can get them just right! Thank you so so much for posting this simply adorable recipe! =]
carrie cook commented on Jun 08 11 at 11:42 amWhat a mess!!! I followed directions exactly…the bottom colour, purple, rose 2/3 of the way up the jar…the blue and green barely visible, and the top 2 colours barely showed. they appeared more tie dyed than rainbow. The second batch did not bake all the way thru but bubbled over…..and also, as many others stated…the cake shrank away from the jar…a lot. As slices, once removed from the jar…the cake was very pretty bit that defeats the entire purpose of cake in a jar! Does anyone have any solutions???
I DON'T BAKE OFTEN commented on Jun 11 11 at 7:03 pmWait, so are you telling me that I can just microwave the cake INSTEAD of baking it? Would all the preparation steps be exactly the same, and would it come out the same way?
I mean, if that’s the case, I know what I’m doing…
B.J. commented on Jun 12 11 at 6:15 pmI made 12 little 8 oz RAINBOW CAKES IN A JAR and they were PERFECT, AWESOME, and DELICIOUS ! :D I had NO problems with the jars turning brown AT ALL ! I followed CHELSEA J.’s advice a few post above here and adjusted the baking time as she did. I *think* I added 3 mins once more and TA DA !!! :) As for the ‘turning brown’ problem, I sprayed my little jars LIGHTLY with BAKER’S JOY [has flour in it] and again…. mine came out perfect !
I wish we could post pictures here, but if you’ll go to DUNCAN HINES on FB… I posted my picture on their wall. GOOD LUCK guys & gals… I WILL be making these again and using different colors.
Lindsey commented on Jun 14 11 at 7:43 pmThis looks awesome! We saw this on Pinterest and are going to have to try it soon! Love the look of the mason jars…
concerned eater commented on Jun 14 11 at 8:30 pmhow do i eat it?
Lexy commented on Jun 16 11 at 12:04 amthis wont break? I keep breaking glass because i put it through too much heat :<
Hannah commented on Jun 20 11 at 4:32 pmI made these at the weekend and they were great! I’ve made rainbow cake before so used a normal cake recipe (125g sugar/butter/ self raising flour, 2 tsps baking powder, 1 tsp vanilla essence, 1 egg, bit of milk) and they made 6 gorgeous cakes! I would advise putting boiling water in the oven instead of normal water, and having the oven very hot. :)
Alicia commented on Jun 25 11 at 2:35 amAwesome! I came across this on stumbleupon earlier today. Now, 4 of my friends and I are making them. :) We’re using a turkey baster to insert all the colors into the jar! Tell you how it turns out soon. We’re super excited about. We’re going to SF Pride tomorrow so it’s perfectly festive.
Sunny Haynes commented on Jun 27 11 at 8:43 pmWe made several batches of these now and they are turning out great … except for the layering. Any ideas?.
Jennifer commented on Jun 27 11 at 11:37 pmMaking these for 4th of July in red white and blue. :-)
shawn commented on Jun 28 11 at 10:39 pmCan I use baby food jars?
Polly commented on Jul 02 11 at 10:25 pmSuper awesome !! Thank you for sharing !! I have a question?? Can I put the frosting and then send it out to my mom in Arizona I live in Texas ?? I just don’t want the cake nor the frosting to go bad ???
Lindsey @ Why Just Eat commented on Jul 03 11 at 9:23 pmI’ve been looking for something fun to do for my daughter’s 6th birthday – I think this will be on our menu for sure!
angelique523 commented on Jul 06 11 at 12:15 amPut the lid on it and send it to me please!
Teresa commented on Jul 08 11 at 12:29 amMy mom and I are hosting a bridal shower this Sunday, and a few weeks ago we were trying to figure out what to make as the dessert. A few weeks ago, I stumbled upon this page and fell in LOVE with this recipe! The only thing we really did differently aside from using wide-mouthed jars (it’s all we could find after hunting through nearly half a dozen different store chains!) was instead of rainbow colors, we went with teal and white stripes. (Teal is the Bride’s favorite color/wedding colors, and white because – well, it’s a wedding shower!) Tonight is the test run to make sure they turn out alright before we serve them to guests – in other words, it’s a chance to eat cake before the bridal shower happens! haha. I’ll post an update once the shower occurs and hopefully I’ll send some pictures if I get the time to take some! :)
ladiebuggg888 commented on Jul 22 11 at 1:50 amI have made a similar recipe for cake in a jar and if you handle it all properly, you can turn put a seal lid and a ring on them, turn them over on a towel and they will self can themselves from the heat of the jar. my kids were eating them for a few months. they did do the shrinkage thing and there was some condensation in the jars but my girls are not fussy and still loved them
Jess commented on Jul 31 11 at 5:54 pmMy question is: can you send frosting in the jar like this? Or if I sent it to a friend should they put on the frosting themselves?
This looks delicious btw!
Sharon commented on Aug 03 11 at 11:43 amThis is the most fun I have had in a long time with a birthday cake! I used jelly jars and they cooked up great!! I wish I would have thought of jars to send birthday cakes to my kids when they were first at college. The 19 year old is going to love her cake in a jar!
lauren commented on Aug 06 11 at 11:23 amI was wondering if a marshmallow Fluff jar is too small for this recipe?
Amanda commented on Aug 06 11 at 12:46 pmAfter reading these reviews, I am kind of nervous to do this recipe. I plan to make a cake in a jar for my boyfriend’s birthday, but decided that I am going to try and take a core out of the jar so that there is frosting throughout the entire cake. It may not go well, but at least it will be fun.
brittany commented on Aug 06 11 at 11:46 pmthis looks awsome!! i am soo going to try this lol :)
Briny commented on Aug 07 11 at 2:50 pmI’m gonna try this with my kids this week!

thanks for sharing

Bethany commented on Aug 08 11 at 11:10 pmok so our stripes all blended to one nasty color…any tips?
Anita L. Williams commented on Aug 09 11 at 8:49 pmUse a skewer to poke down in the middle of the cake to test if it’s done. I can think of all kinds of fun things to do with this idea. Thanks!
Capability commented on Aug 11 11 at 6:56 amLove this! I made Whisk Kid’s rainbow cake http://bit.ly/aDKEEh which is gorgeous but way more work! I have some smaller mason jars and think this is a great idea – Thanks!!
StinaStew commented on Aug 12 11 at 9:16 pmMade these earlier this week w/my hubby & we layered, however, the layers didn’t work even close to what the pic displays. Our bottom color was prominent & others kinda just went in the middle. Once baked, the outside still had the same prominent color, but the middle was neat. It was sort of like tye-dye. We used only 3 jars for the cake mix bc it was about as full as the pic on here, but grew out of the top of the jar! This time, we are trying 1 color for each of the 4 jars this time. Going to see if that makes a difference. Still fun concept!
omar commented on Aug 13 11 at 11:44 amlove your post..

Miss Cuisine commented on Aug 18 11 at 5:20 amI am impressed with the beautiful results, congratulations. I put forward on my French blog with a link to this article (http://www.untourencuisine.com/recettes_De_belles_idees_venues_d_ailleurs/91_3084).
Lorrie Scott commented on Aug 18 11 at 10:54 pmI need to try this with the neon dye. I have baked cakes in jars since the 80′s. If you use potholders and put the canning jar lids and rings on them, straight from boiling water, when the cake comes hot from the oven, and place the seals on, they will ping like jam, and will have a much longer shelf life…sealed and sterile!
kelli commented on Aug 25 11 at 10:35 pmI made these today!!! So cute!!! But after i let them cool a bit, i frosted and put a lid on the jar and when I went to serve them later they had shrunk inside the jar!! Like they got skinny in there…has that happened to anyone else? Any suggestions??
Candin commented on Aug 26 11 at 5:58 pmI saw this image on pinterest and tracked it down to here! I loved it so much that I featured it on my blog below! Thanks for the creativity!!
Jessica Lang commented on Sep 04 11 at 1:50 amI made these today and they looked horrible!! I put the layers bottom to top…purple, pink, blue, yellow, green…and they turned out like a big brown blob. What did I do wrong?
Justmyperfectwedding commented on Sep 07 11 at 7:24 pmI loved it.
I featured it in our blog with more than 1500 notes and people loving it!:)

Diane commented on Sep 12 11 at 5:35 pmomg i love it!!!! i will be trying this very soon , thank you so much
gudrun commented on Sep 13 11 at 1:37 pmdo you put the jar in the oven ?
Andrea commented on Sep 14 11 at 6:45 pmHas anyone tried this with the natural food colorings? My daughter can’t have artificial dyes but can have the natural food based dyes. I know they won’t be vibrant like these but would they work?
Becca commented on Sep 22 11 at 12:11 pmI made these yesterday in the half pint jars for our sons 8th birthday. I used 1 less color in the layering process. They were a hit with the family. The only complaint was that they were a little doughy at the bottom. We sealed one and will see how it holds up over time. Thank you for this wonderful idea!!!!!
stephanie commented on Sep 23 11 at 9:33 pmAdorable idea :)
Barbara commented on Sep 24 11 at 5:37 pmReally nice! I’ll try to make it, my children will like it! :)
Aubrey commented on Sep 30 11 at 8:28 pmDo you know where I can purchase Neon Food Coloring? I am so excited to make this cake!!!
3fita commented on Oct 10 11 at 12:21 amthis looks super delicious!! i am excited to try this out!! i’ve read all the comments, and i think i’m ready.. wish me luck! :)
Heather commented on Oct 12 11 at 2:42 amI made these for my sister’s 16th birthday this weekend. I was frustrated because spooning on 3 table spoons of each color into the jars equalled only half of a jar of cake once cooked. The cake peaked like a little mountain, and I was very disappointed with out it turned out. The last one I made was with left over batter, which was about 1/2 cup of each color, and that one turned out perfect.
ALSO, I “throughly” sprayed the first jar with cooking spray, only to have the purple color seep up the sides and make a gross looking color. So, for the other jars, I sprayed a light coat of spray, and then actually wiped out the spray, leaving only a small film of non-stick spray on the jar itself. This worked much better, but still not perfect like the on pictured above.
Lora commented on Oct 15 11 at 10:02 pmcan you make these in baby food jars?
Ellie commented on Oct 19 11 at 7:51 amTry cooking the bottom two layers before adding the top.. otherwise they don’t cook properly. I also made my own buttercake, I hate the packet ones… perfect tasting and very simple!
90g butter, softened
1/2 cup caster sugar
1 cup plain flour
1 tsp vanilla essence (optional)
2 tsp milk
2 eggs
Mix with electric beater until just combined, then mix thoroughly with a wooden spoon. Add food colourings and follow rest of recipe.
Soooooo tasty.
pat commented on Oct 20 11 at 5:51 amBake the cakes in a cake pan, slice, then spoon in the cake, Frost and decorate
renea turner commented on Oct 29 11 at 10:40 amwill this work w/ baby food jars? happen to have some that have no lids & can’t think of what to do w/ them.
Traci commented on Nov 07 11 at 9:04 pmMade these for a practice run for my daughter’s 4th birthday. Needless to say they did not turn out like the picture. The colors were not as vibrant and I used neon die. The outside of the bottom of the cake was undercooked–I stuck them back in the oven so hopefull that helps. Not sure if I will be making these for her party. I have seen a layered rainbow cake turn out much better. Looking for ideas to improve this if anyone can help bc I love the idea and really want to use it. I used the half pint wide mouth jars.
Any advise would be greatly appreciated.
Jolee commented on Nov 15 11 at 6:16 pmHello I was wondering if this would be ok in smaller jars? like 6 oz or so. If I planned to do a jar/ kid at my daughters birthday party. How long do you think I should cook them? ~ Jolee
Tiffany commented on Nov 24 11 at 1:12 amI made these tonight as a trial run for my sons “Christmas in Candyland” theme party. I had the same issue with the purple on the bottom layer taking over the whole jar. The inside was awesome though. I think I am going to try the tip some other ppl gave. 1.) less oil in the jar. 2.) thicken up the batter a little. 3.) put the bottom color in, bake it a little bit, then add the next layer and so on. I really think that will help with the layered look on the outside! As for the vibrant colors, I used a LOT of food coloring and my colors turned out super bright! I think for the shrinking problem, just fill the jars up more, like 3/4ths full and when it spills over that is fine, you can just clean it off and level off the top! I have made rainbow cupcakes many times an have used this recipe because it makes the cake firmer and gives that “bakery” taste….
Take a normal cake mix, mix the box mix with the oil that is called for, three eggs, and one cup on buttermilk. VERY good! Also, I use the boxed buttercream frosting (Wilton??) that you can get at Walmart or hobby lobby in the wedding craft isle. It is delicious and easy. Just add a couple tsp of milk then mix and violia!! Hope this helps with some of your questions! I will be trying to make again in a few days and I will keep you posted!! :)
janelle commented on Nov 29 11 at 4:11 pmawesome idea! i’m definitely going to try this for my friends birthday :)
Lacie commented on Nov 29 11 at 5:03 pmI made these twice over the holiday and had issues with the bottoms becoming soggy after baking. The first time I thought maybe I didn’t cook them quite long enough as I am from San Diego and was in Oregon for the holidays….then the second time around they seemed cooked all the way through ( toothpick came out clean) bit when I returned after Thanksgiving dinner they were soggy again…..help…..what did I do wrong?!?
Ashley commented on Dec 04 11 at 2:57 pmAs I was reading this recipe, I was thinking that perhaps it might be a sufficient idea to find some sort of round hollow device to put in the middle of the jar and add the batter around it, so that it will cook all the way through, as well as provide a nice hollow crevice to apply icing throughout the cake, rather than just at the top. I haven’t tried this recipe, nor the alteration i have suggested. ….it was just a thought.
Angela commented on Dec 05 11 at 9:56 amI made these as a trial run last night for my daughter’s birthday party and they came out perfect! They did spill out a little outside of the jars, but I expected that and it was an easy clean up to wipe the outside of the jars clean and cut off the tops to make it even. I used the half pint jars and took the advice of previous commenters: I used Baker’s Joy (but I forgot on my second batch and they still didn’t brown like others have mentioned) and I use the Duncan Hines Moist something-or-other WHITE cake mix. I used a combination of neon food coloring and gel coloring to get the colors I wanted. I used 6 colors in my first batch, but the layers were too thin for my liking so I went to 5 for the second batch. I used equal amounts of all the colors, but on the next one, I would use less of the top color because it becomes the largest “color band” in the jar–I used two spoonfuls of each color, but would probably only use 1 spoonful of the top color next time. I think I ended up baking the jars for about 30 minutes total @ 350. I also put the pan with water in it in the oven while it was preheating to make sure the water was warm before I added my jars. I think the issue with the bottoms not cooking is because the cold water in the pan is not heating up as quickly. Hope this helps!
Erica commented on Dec 08 11 at 11:13 pmHello! I was wondering if you think it is a good idea to send this in the mail to my husband who is deployed. Do you think it would still be good once it got to him? Thanks!
nancy commented on Dec 12 11 at 8:56 pmVery interesting a innovation, not only have the rainbow, and other. Looking forward to it.
Tanya Bannwart commented on Dec 18 11 at 9:58 pmThese look so absolutely amazing I just couldn’t wait to try them. In fact, my plan was to make them and give them as gifts for Christmas. Unfortunately they were an epic fail for me. I’ve tried a variety of cooking combinations and nothing’s worked. Pam and Flour on the sides of the jars to help the batter climb; flour coating looks burnt, cake barely rose. Pam only in the jars; cake still looks overly brown and didn’t rise that much. Oven higher temp, oven lower temp. Longer cook time, shorter cook time. Water bath. No water bath. Everytime the results are the same, brown edges, barely rose. The cake looks delicious when you look down into the jar, but through the glass you can barely tell there’s different colors behind the brown edges. Am currently cutting the cake out of the jars to turn into rainbow cake pudding. Bummer. Absolutely love the recipe. Just can’t figure out what I did wrong. Hope everyone else has better luck because these look amazing.
Kizy Mcloughlin commented on Dec 21 11 at 2:16 pmOkay i made these and i noticed this:
. Male sure you have lots of Red for the top
. Keep checking on them when they’re in the oven so they don’t go brown!
. It takes a lot of patience!
. They didn’t fill the jar (they were way too small)
. They do actually work! :D have fun making them- they are cute Xmas presents and i think everyone is gona like mine mine because even though they look a little…. “messy” i have the excuse of the fact i’m only 12 :D
Monica commented on Dec 24 11 at 2:51 pmAfter reading all the comments I didn’t notice a response to “why does the cake shrink?” Immediately upon removing the jars from the oven, the cake began to shrink away from the jar. Also, the cake is a little brown, but no biggy; but how are your cakes NOT browned?
Paula commented on Dec 29 11 at 8:42 amWould you mind sending me an invite to pintrest? My email is oceana33@aol.com. I would love to pin this idea but it take so long for them to invite me. Thanks
Katie commented on Dec 29 11 at 2:47 pmI made this cake today for my friends birthday. How do you get such vivid color on the outside? The inside has great color but the outside is a little brown. How do you prevent that?
the original Sarah commented on Jan 10 12 at 8:05 amClever! I love it! Did you know if you layer the colors in a bunt pan it creates a rainbow arch? Perfect for making a rainbow shaped cake. http://livinggorges.blogspot.com/2012/01/its-rainbow-unicorn-birthday-party-part.html
Susan commented on Jan 10 12 at 12:25 pmGreat idea!
Sending one to my 41 year old son tomorrow.
Madeline commented on Jan 12 12 at 5:25 pmI just added this to my recipe binder. Brilliant!
Kimberly commented on Jan 15 12 at 9:17 amBaby food jars work well for a smaller version but this was great! Thanks!!!
Kris commented on Jan 16 12 at 10:05 pmThese were a huge hit, thank you!
Shea Goldstein commented on Jan 17 12 at 2:47 pmWhat a fabulous idea! I have to do this for my kids…
JoyHey commented on Jan 20 12 at 7:25 pmLOVE! Thanks! Trackback: http://blog.joyhey.com/2012/01/17/inspiration-rainbow-party/
Ashley commented on Jan 22 12 at 2:18 amI would LOVE to make these for my son’s 1st Birthday coming up, but it seems liek I will have to do a few test batches based on all the comments. I would liek to use baby food jars, has anyone used them, and have any tips? Thank you so much in advance!
cookiemom commented on Jan 29 12 at 3:27 pmI’m wondering if you should remind people that the water in the pan should be up to oven temperature before you put the jars in to bake? I usually put boiling water in the bain marie. Using cold water would keep the bottoms of the cake jars from baking properly.
Brooke commented on Feb 03 12 at 10:36 amHave the jars ever shattered? I love, love, love the way these look and really want to make them, but I am petrified due to past glass baking explosions.
Lisa @ Snappy Gourmet commented on Feb 05 12 at 8:00 pmSo cute!!
Emma commented on Feb 20 12 at 1:32 amWhere did you get the jars from??
Natasha commented on Feb 20 12 at 7:48 amJust a quick question..are you even allowed to put glass jars in the oven at that temperature? Won’t the crack or explode?
linda millen commented on Feb 20 12 at 11:17 amHow long will these last in the jar. just thinking on sending to some soliders in korea. i could send the icing and sprnkles separately.
Have a good day
Linda
Loreli commented on Feb 20 12 at 6:23 pmThis is such an awesome idea for party favors! So much easier to store than regular cupcakes because you don’t have to worry about bumping them and ruining the icing! I made these little cakes in solid purple for my mom’s 50th birthday using the stage 2 size jars and they turned out great. I painted the lids with flat black spray paint and glued a purple plastic gem to the top, wrapped a square of black tulle and a 1″ wide purple and black zebra print ribbon around the jar and they were the hit of the party. They did brown a little so I think next time I will stick to chocolate cake so that it’s not so noticible. I would also recommend only filling 1/3 of the jar to avoid them overflowing durring baking.
To those of you who are worried about babyfood jars breaking… these jars are made to withstand heat because they have to be sanitized in the canning process. I’ve baked in the same stage 2 jars twice so far and haven’t had a problem.
Laura commented on Feb 22 12 at 6:46 amI’m over in the uk and i really want to try this but do i need to convert the 350 degrees? As my oven doesnt even get close to that! I think it would be around 180 degrees for me? Please let me know (if anyone knows!)
