Equipment

  • Baking Pan
  • Mixing Bowl
  • Microwave

Ingredients

Brownie Base

  • 1 box Double chocolate premium brownie mix 18 oz, use as directed
  • 1 large Egg room temperature
  • 1/3 cup Vegetable oil or any neutral oil
  • 1/4 cup Water room temperature

Marshmallow Layer

  • 1 jar Jet-puffed marshmallow creme 7 oz, spreadable
  • 1/3 to 1/2 cup Sweetened flaked coconut optional to taste

Topping

  • 2 cups Milk chocolate chips for melting
  • 1 cup Chunky peanut butter creamy or chunky works
  • 3 1/2 cups Cocoa krispies cereal or similar chocolate puffed rice cereal

Instructions

  • Preheat your oven to 325°F (163°C). Lightly grease a 13×9-inch baking pan and set it aside.
  • In a medium bowl, add the brownie mix, egg, vegetable oil, and water. Mix until fully combined and smooth.
  • Spread the brownie batter evenly into the prepared pan.
  • Bake for 35 to 45 minutes. Check at 35 minutes; a toothpick should come out with a few moist crumbs.
  • Let the pan cool completely on a wire rack.
  • Spread the marshmallow creme evenly over the cooled brownie layer.
  • In a microwave-safe bowl, combine the chocolate chips and peanut butter. Microwave in 1-minute intervals until melted and smooth.
  • Stir the cocoa krispies into the melted chocolate-peanut butter mixture until evenly coated.
  • Spread the chocolate-peanut butter-cereal mixture over the marshmallow layer, pressing lightly to adhere.
  • Cover the pan and refrigerate for at least 2 hours to set.
  • Once set, cut into bars and serve chilled or at room temperature.
