This tutorial shows how to make a two layer rainbow cake. I used Duff Electric Color gels and Wilton gels for the colors of the rainbow.
Evenly separate you cake batter into 6 bowls and line up your icing colors. You will need purple, blue, green, yellow, orange, pink. I use mostly Duff brand electric colors and fill in with Wilton yellow and orange.
My son always loves to help with this part. Squeeze a few drops in each bowl of batter and stir well.
Here are the colored batters ready to be layered in two round pans.
Gently pour and spread out the batter in layers. One pan will get pink, orange and yellow in that order. The other pan will get green, blue and purple in that order. They look like this after they bake.
Fill and ice the cakes. Be sure that the purple color is facing down and the pink color is facing up.

All smoothed out.
This is how it looks inside when you slice the cake. So fun for a kid’s birthday cake!
