This recipe calls for my famous buttercream frosting. You can find that recipe here. For rainbow recipes, it’s better to use a box cake. With homemade cakes you can over-mix the batter when coloring and it knocks the air out. Box cakes can handle the mixing and perfectly hold that color.

Instructions:

  1. Preheat a moderate oven (175°C/350°F)
  2. Combine box cakes, eggs, milk, and butter an electric mixer, and beat until mixed.
  3. Once mixed, divide the batter into the six small bowls.

  4. Add a fair amount of food color to each bowl and mix well.
  5. Transfer all the colored batter into their own individual snap seal bags. Then, use a pair of scissors to cut a generous corner from each snap seal bag.
  6. Generously spray the 6’’ cake tins with a nonstick spray.
  7. Pipe one color batter into each cake tin. Use the back of a spoon to flatten the tops of the cake.

  8. Place into a moderate oven for 14 minutes.
  9. Remove cake from the oven, and transfer to a cooling rack until they are completely cool.
  10. Freeze for about 1 hour.
  11. Use a serrated edge knife to cut off the tops of all the layers of cake.  Then, trim off the brown layer from the bottoms of the cakes.

  12. Take your red, orange, and yellow cake and stack them on top of each other. Use a serrated edge knife to trim away the brown from the edges of the cake so that it’s nice and even.
  13. Repeat this with green, blue, and purple.
  14. Use the large circle cutter to cut a large circle out of each layer of cake. Then, use a smaller circle cutter to cut a small circle out of the smaller layer of cake. You should a large hollow ring, a smaller donut like piece, and a center circle. Do this for all your cake pieces.

  15. Add a thin layer of buttercream to the inside of each layers.

  17. Smear buttercream frosting onto a cake board. Place a blue, green, and purple layer on the top of the buttercream. Frost the top of that layer with buttercream frosting. Then, add another layer on top. Make this red, orange, yellow layer on top. Frost, the top of that layer and continue to alternate.
