Get some vanilla and chocolate cake mix, some chocolate chips, food coloring, and a few other types of chips or candies. Make the batter, then layer the batter and fillings in the cupcake paper. Bake as directed. When cooled, take a large straw and push it into the cupcake. Remove the cupcake “core” from the straw and see if you can analyze it. Then eat it!
