This is not so much a recipe as it is a method. Since there were going to be 3 kids of eating age (my son is just 5 months and there was another baby there too) I wanted to make a dessert that would appeal to the kids. So I made these cupcakes.
1 box white cake mix plus other ingredients as called for on box
Put cupcake liners in muffin tins. Mix cake batter according to box instructions. Divide batter into 5 bowls. Add food coloring to each bowl to make desired colors (I did red, orange, yellow, green, and blue). Spoon colors one at a time into cupcake liners. Cook cupcakes in oven according to box instuctions. Frost as desired.
