Ingredients

Units Scale

Brownie Base

  • 18.4 ounce package Pillsbury™ Chocolate Fudge Brownie Mix
  • 2/3 cup vegetable oil
  • 1/4 cup water
  • 2 eggs

Marshmallow Frosting

  • 12 ounce container Pillsbury™ Vanilla Marshmallow Fluffy Frost™

Topping

  • 2 cups (12 ounces) semisweet chocolate chips
  • 1 cup peanut butter
  • 1 tablespoon butter
  • 1 1/2 cups crisp rice cereal

Instructions

  1. Prepare the Brownie Layer: Follow the package directions to combine the brownie mix with vegetable oil, water, and eggs. Pour the batter into a greased 13×9-inch baking pan and bake at 350°F (175°C) for 30 minutes, or until a toothpick inserted in the center comes out clean. Remove from oven and allow to cool for about an hour.
  2. Apply Marshmallow Frosting: Spread the Pillsbury Vanilla Marshmallow Fluffy Frost evenly over the cooled brownie layer, smoothing it out with a spatula.
  3. Make the Crunch Topping: In a small saucepan, combine the semisweet chocolate chips, peanut butter, and butter. Cook over low heat, stirring constantly until the mixture is smooth and melted. Remove from heat and quickly stir in the crisp rice cereal until evenly coated.
  4. Assemble the Bars: Immediately spoon the chocolate-peanut butter rice cereal mixture over the marshmallow frosting layer. Gently spread it out to form an even layer. Chill the entire pan in the refrigerator until the topping is set, about 1-2 hours.
  5. Serve: Let the bars sit at room temperature for 10 minutes before slicing into 20 squares. Enjoy cold or at room temperature.

Notes

  • Ensure the brownie layer is completely cooled before adding the frosting to prevent melting.
  • Chill the bars thoroughly for a clean cut and better texture.
  • Feel free to add chopped nuts or additional toppings for variation.
