In addition to decorating the outside of your cake like a rainbow you can actually bake up a colorful rainbow cake on the inside. It’ll be a super colorful surprise when you cut it open.

Double Rainbow Cake
Servings
Ingredients
- Raw prepared yellow or white cake batter for 1 9-inch round cake
- Food coloring to match the colors of your rainbow
Instructions
- 1 Divide the raw batter into 6 bowls (if doing the full rainbow). Put slightly more batter in the first bowl and a little less in each subsequent bowl. 2 Mix a single color of food coloring into each bowl until thoroughly combined and desired color is achieved. Use a small amount for pastel colors, and more for bold, vibrant colors. 3 Take the first color (red if you are doing the colors of the rainbow) and spoon into the very middle of a well-greased 9-inch round cake pan. Tilt it slightly to spread. Don’t worry, the batter does not have to spread to the edges, it will eventually. 4 Take your next color and carefully pour it directly into the middle of the first color. Once in you can again tip a bit to spread it out some, but do not stir. 5 repeat with remaining colors and bake according to package directions. 6 Once cool, follow directions to decorate the outside of the cake in our Basic Rainbow Cake tutorial.
