The best part of any party is the food, and nothing is better than Rainbow Party food because most of it includes my favorite thing: sprinkles! Almost any dessert or treat can fit into the rainbow theme with a few sprinkles, including your traditional Rice Krispie Treat. A little Funfetti Cake Mix and a whole lot of sprinkles turned our Rice Krispie treats into the perfect party dessert. See how to make them below.
