Prep Time 15 minutes


  • 1 bag marshmallows 16 ounces
  • 7-7.5 cups (280-300) Rice Krispie cereal
  • 2 tbsp (28.25 g) unsalted butter
  • 4 tbsp (28.75 g)white cake mix
  • 2 tsp (13 g) clear vanilla extract
  • 4 tbsp (35 g) rainbow sprinkles


  • Spray a 8x8" or 9x9" pan with non-stick spray (you can also use a 9x13" pan but the Rice Krispie Treats won't be as thick). Set aside.
  • In a microwave safe bowl, combine the butter and the marshmallows. Microwave for about 1 to 2 minutes, until the marshmallows are big and fluffy.
  • Stir the marshmallows and butter until smooth. Add the cake mix and extract and stir until well blended.
  • Gradually add the Rice Krispies and coat well with the marshmallow mixture. Add the sprinkles and stir to mix.
  • Pour the Rice Krispie treats into your prepared pan. Wet your hands slightly with water and then pat down the Rice Krispie Treats. Let sit, uncovered, at room temperature for about an hour before serving.
