Double rainbow (OMG) cake!

Sometimes, it’s as if everything happened just as it should. As if I were meant to find this rainbow cake recipe more than a year ago and never make it until… As if my friend Ben had never sent me the most awesome video ever, Double Rainbow (a.k.a. Naturegasm), which makes me cry with laughter every single time… As if I hadn’t seen this even awesomer Double Rainbow remix, which I could watch on repeat…

To quote the video, “What does it mean?!?

Now, you don’t have to cry like the guy in the video, but this is pretty neat. I also like to call this my Psychedelic Cake, Anna’s Technicolor Dream Cake and the Tie-Dye Cake.

All rainbowness aside, the cake is very tasty, albeit completely Semi-Homemade. That makes it perfect for kids, if you have them. The Sprite keeps it nice and slightly tangy and the whipped topping makes a pillowy frosting. I took the leftovers to work and all that remained were a few rainbow crumbs.

Double Rainbow (all the way across the sky) Cake!


  • 2 boxes white cake mix (buy the appropriate number of eggs and oil)
  • 2 cans Sprite
  • gel food coloring
  • 16 oz fat-free whipped topping
  • 2 oz instant fat-free sugar-free pudding mix (2 boxes)

Preheat oven to whatever the box says. Mix the cake mix with the soda according to regular instructions on box. It will be lumpy afterward. Separate into six bowls, a little over 1 c. in each. Mix in the colors of the rainbow…ROY G. BIV. You will be impressed with the gel food coloring. It’s less messy and the colors are so vivid!

Now, butter and flour two cake pans. In the first pan, pour half the red, then orange, then yellow, etc. ON TOP OF EACH OTHER. So the blobs of color will spread out but not mix. In the other pan, do the same, but with the colors in reverse over: purple, blue, green, etc. It will look like this:

Bake the cake for however long the box tells you to bake it. Let cool completely before moving to a wire rack.

Meanwhile, make your frosting by mixing the pudding and whipped topping until smooth. Add frosting in between the cake layers and all over the top, of course!

Enjoy, friends! I know you will … xoxo

  1. Wait, I’m confused. Are you subbing the soda for something? Or just adding additional liquid?

  2. Yes, you substitute the soda for the water in the cake-box instructions. Use the regular amounts of eggs and oil.

  3. Yum! And so pretty!

  4. Love this! Will totally have to try. It seems so much easier than the checkerboard cake I’ve made.
