Ingredients:

  • 4 tbsp unsalted butter
  • 10 oz mini marshmallows
  • 6 cups rice krispies
  • 1/2 cup yellow or white cake mix
  • 1 tsp vanilla extract
  • 1/4 cup rainbow sprinkles

Instructions:

  1. Place the dry cake mix in a microwave-safe bowl. Microwave on high in 30-second intervals, stirring in between, until the mix reaches 160°F (71°C) or smells slightly toasted. Set aside.
  2. Melt the butter over low heat in a pot. Once bubbling, add the marshmallows and stir constantly with a rubber spatula until the mixture is smooth and glossy. Remove from heat immediately.
  3. Quickly stir in the vanilla extract and the heat-treated cake mix. Once integrated, fold in the rice krispies and rainbow sprinkles, stirring gently until the cereal is evenly coated.
  4. Line an 8x8 inch baking pan with parchment paper. Transfer the mixture to the pan and press down lightly with a greased spatula.
  5. Allow the treats to cool for 30 minutes before slicing into 16 squares.
