Rainbow Spatter Cupcakes! Using white cake mix, make batter as directed. Use several plastic (or glass) cups, pouring white batter in them, divide between all cups. Add food coloring to each cup for the colors desired. Mix each cup and then put a little of each color in each muffin cup in small blobs. Then drizzle other colors over the blobs. Bake as directed.
Great idea! To create easy to decorate pull-apart cupcake cakes, place the liners into shaped pans. Then, pour the cupcake batter in and bake. The cupcakes will conform to the pan and create different shaped cupcakes that are still easy to separate.
