Notes
For a 15 ounce box of cake mix use 3 eggs, ⅓ cup of butter, and ½ cup of milk.
To make this recipe dairy-free use non-dairy milk.
To make a marbled rainbow cake: Grease a baking pan (size and baking times should be according to box). Color the batter according to the directions above. Scoop the batter into the cake pan, alternating colors. Rest for 10 minutes before baking. The rainbow cake will have a swirled pattern rather than layers.
