To bake the multicolored cake:

Step 1

Prepare the white two-layer cake mix. Divide the batter into four portions. Use food coloring to tint the batter four different colors.

Step 2

Spread one of the colors into the bottoms of two greased and floured 8" round pans. Bake at 350° for 12 to 15 minutes or until set.

Step 3

Spread another color of batter on top of the baked layers and bake for another 12 to 15 minutes. Repeat until all layers are baked; cool in pan for 10 minutes.

Step 4

Remove from pans to wire rack. Cool completely.

Decorating option #1 (pictured): Divide store-bought white frosting into four bowls. Add different food coloring to three of them to tint frosting to desired colors. Assemble cake layers and spread or pipe around cake in stripes to create a multi-colored effect.

Decorating option #2: Assemble cake and frost in store-bought white frosting. Use colored sugars to create a rainbow effect on the cake.
