Step 1
Divide cake mix into 5 small bowls. Add 1/4 cup water + 2 tbsp oil + 1 egg to each (or use egg substitute).
Step 2
Stir each bowl until just combined, then add 3-4 drops of a different food color to each. Mix until color is even.
Step 3
Spread each colored batter into a parchment-lined 6-inch round cake pan or a thin layer on a sheet pan.
Step 4
Bake at 350°F for 12-14 minutes until a toothpick comes out clean. Cool completely on a rack.
Step 5
Beat softened butter + powdered sugar until fluffy, about 2 minutes. Divide frosting into 5 bowls and tint each to match cake layers.
Step 6
Stack cake layers with frosting between each, then frost the outside. Chill 5 min, slice, and serve.
