Funfetti Rice Krispie Treats

Created by: Courtney
Prep Time 15 minutes
Cook Time 5 minutes
Resting Time 1 hour
Yield: 12 servings
These funfetti rice krispie treats are a sweet, sprinkle-filled twist on the classic no-bake favorite! Made with gooey marshmallows, crisp rice cereal, a touch of cake mix for that irresistible birthday cake flavor, and a generous handful of rainbow sprinkles, they’re as fun to make as they are to eat. Perfect for parties, bake sales, or any day that needs a little extra color and joy!

Equipment

Ingredients 

  • 1 cup white cake mix
  • ½ cup unsalted butter
  • 20 oz mini marshmallows
  • 2 tsp vanilla extract
  • ½ tsp salt
  • 7 cups Rice Krispies cereal
  • 2 cups mini marshmallows
  • ⅓ cup rainbow sprinkles

Instructions

  • First, heat-treat the white cake mix. Pour the cake mix into a microwave-safe bowl. Heat in the microwave in 30 second intervals, stirring in between, until the cake mix reaches 160℉ (71℃), approximately 1 to 1 ½ minutes total. Run the cake mix through a fine mesh strainer and set aside to cool.
  • Prepare a 9x13 baking pan with nonstick cooking spray and parchment paper. Extend the parchment paper up the sides of the pan to easily remove the rice krispie treats from the pan.
  • In a large saucepan on the stovetop over medium-low heat, melt the unsalted butter. Add in 20 ounces of mini marshmallows and stir until the marshmallow mixture is melted and smooth. Remove the saucepan from the heat.
  • Stir in the heat-treated cake mix, vanilla extract, and salt. Then, fold in the Rice Krispies cereal and additional 2 cups of mini marshmallows until the cereal is well coated in the melted marshmallow mixture.
  • Pour the rice krispie treat mixture into the prepared baking pan. Moisten your hands with water, and gently press the mixture into the pan creating an even layer. Sprinkle the rainbow sprinkles over the top of the rice krispie treat bars.
  • Allow the rice krispie treats to set up in the pan for 1 hour before removing and cutting into squares.

Notes

Storing & Serving:
  • Room temperature: Store the rice krispie treats in an airtight container or resealable storage bag at room temperature for 2 to 3 days.
  • Refrigerator/Freezer: I do not recommend storing rice krispie treats in the refrigerator or freezer as it can impact the texture.
