I found such a cool recipe for rainbow cake on Omnomicon, and just had to post about it. It seems pretty easy to make. Two boxes of vanilla cake mix, some gel food colouring, jelly (American Jello), and Sprite Zero (instead of eggs, oil and water apparently!)
However, for those of you who do not use the same cake mix, and like me, are scared that the Sprite Zero might mess up the recipe, you can follow the instructions of the cake mix packet. Depending on the number of gel colours you have, divide the batter into equal parts.
Drop the colours, one by one, into the middle of the pan, in neat concentric-ish gobs. Remember the cake is going to be sliced in the side there, so mixing it around on top isn’t going to make your slices any more psychedelic (trust me, I did the three-dimensional thinking for you already).
When you’re three colours in, start doing the reverse with the other pan. Since I’m going in rainbow order: red, orange, yellow, green, blue, purple, I got from red to yellow in the first pan, then purple, blue, green in the second. This is so that your two pans are equal if your measurements aren’t exact (and they’re not likely to be).
Tips From Aleta
For the frosting recipe, see Omnomicon or buy ready to use frosting – I LOVED the Devil’s Food frosting which is available in England – absolutely delicious, but I’m sure traditional frosting will be just as tasty.

I wud love to make this cake for my 5 year old daughter’s party – however do you have any idea where i could source the gel colours in south africa ?
Many Thanks
Hello Felicia
Before reading the recipe I didn’t even know that these gel colours existed! But then I started looking out for them, and found them at Baker’s Bin. The colours are a bit more pricey than normal food colouring but well worth it.
Check http://www.bakersbin.co.za/ for the store closest to you.
Best of luck!!
I made this cake in a bundt pan and my son decorated it to look like a Space Ship for Cub Scouts! Was very cute but when we cut the cake was when we got the most reaction! Everyone loved it and I spent the rest of night explaining how we did it! I’ve made the cake mix several times since then and am now getting ready to make a Flip Flop cake with this recipe! You will be amazed at how moist and delicious this cake really is! I’ll never use Eggs and oil again!
