Ingredients

  • 2 boxes vanilla cake mix (two 15.25 oz boxes)
  • 1.5 cups water
  • ½ cup neutral oil
  • 1 set food coloring (gel, 5+ colors)
  • ½ cup butter
  • 2 cups powdered sugar

Instructions

  1. 1

    Divide cake mix into 5 small bowls. Add 1/4 cup water + 2 tbsp oil + 1 egg to each (or use egg substitute).

  2. 2

    Stir each bowl until just combined, then add 3-4 drops of a different food color to each. Mix until color is even.

  3. 3

    Spread each colored batter into a parchment-lined 6-inch round cake pan or a thin layer on a sheet pan.

  4. 4

    Bake at 350°F for 12-14 minutes until a toothpick comes out clean. Cool completely on a rack.

  5. 5

    Beat softened butter + powdered sugar until fluffy, about 2 minutes. Divide frosting into 5 bowls and tint each to match cake layers.

  6. 6

    Stack cake layers with frosting between each, then frost the outside. Chill 5 min, slice, and serve.
