  • Total Time: 45 minutes
  • Yield: 20 servings

Ingredients

Brownie Base

  • 18.4 ounces box brownie mix (for 9x13-inch pan, plus ingredients per box instructions)

Marshmallow Topping

  • 4 cups mini marshmallows

Peanut Butter Chocolate Rice Krispies Layer

  • 3 tablespoons butter
  • 1 cup creamy peanut butter
  • 1⅓ cup semi-sweet chocolate chips
  • 2 cups Rice Krispies cereal (or Crispy Rice)

Instructions

  1. Prepare the Brownies: Follow the directions on the back of the boxed brownie mix to prepare the batter, then bake the brownies according to package instructions in a 9x13-inch pan.
  2. Add Marshmallows: With about two minutes left of the baking time, remove the brownies from the oven and evenly spread 4 cups of mini marshmallows on top of the hot brownies. Return to the oven and bake for the final two minutes to allow the marshmallows to melt and lightly brown. Remove from oven and let the pan cool completely.
  3. Make the Rice Krispies Mixture: In a microwave-safe bowl, combine 3 tablespoons butter, 1 cup creamy peanut butter, and 1⅓ cups semi-sweet chocolate chips. Microwave on high for 30 seconds, stir, then microwave in 15-30 second increments, stirring each time, until the mixture is melted and smooth.
  4. Add Rice Krispies: Gently stir 2 cups Rice Krispies cereal into the melted peanut butter and chocolate mixture until all the cereal is well coated.
  5. Assemble the Top Layer: Spoon the Rice Krispies mixture over the marshmallow-topped brownies and spread it out evenly to cover the entire surface.
  6. Set and Serve: Refrigerate the assembled brownies for at least 1 to 3 hours to let the top layer set firmly. Once set, cut into squares and serve.

Notes

  • Use mini marshmallows for better melting and even layering.
  • Microwaving times may vary; stir frequently to prevent burning the chocolate mixture.
  • Refrigeration ensures the top layer firms up for easier slicing.
  • You can substitute peanut butter with any other nut or seed butter if desired.
  • For extra texture, consider adding chopped peanuts or sprinkles on top of the Rice Krispies layer before it sets.
