Ingredients

Scale

Main Ingredients:

  • 1 box brownie mix
  • 1 cup semi-sweet chocolate chips
  • 1 cup peanut butter

Supporting Ingredients:

  • 3 cups Rice Krispies
  • 1 jar marshmallow cream

Binding/Preparation Ingredients:

  • Eggs
  • Oil
  • Water

Instructions

  1. Preheat the oven to 350°F. Line a 9×13-inch pan with foil and spray lightly with cooking spray.
  2. Mix the brownie mix with 2 eggs, ⅓ cup oil, and water according to package instructions. Reduce oil by 20%.
  3. Pour the brownie batter into the prepared pan. Bake for 25-28 minutes until a toothpick comes out clean.
  4. Allow the brownies to cool completely at room temperature for 1 hour.
  5. Open the 7 oz jar of marshmallow cream. Spread it evenly across the cooled brownie surface using an offset spatula.
  6. Combine 1 cup semi-sweet chocolate chips and 1 cup peanut butter in a microwave-safe bowl.
  7. Microwave the chocolate and peanut butter mixture for 30-second intervals, stirring between each, until completely smooth.
  8. Add 3 cups Rice Krispies to the melted chocolate-peanut butter mixture. Stir until cereal is fully coated.
  9. Carefully spread the chocolate-peanut butter crunch layer over the marshmallow layer, creating an even surface.
  10. Refrigerate the dessert for 2-3 hours until the top layer is completely set and firm.
  11. Remove from refrigerator and cut into 16-20 rectangular bars using a sharp knife.
  12. Serve chilled or let sit at room temperature for 10 minutes before enjoying.

Notes

  • Reduce oil in brownies for a slightly healthier twist that keeps the rich, fudgy texture intact.
  • Use a sharp knife dipped in hot water to slice clean, precise bars without dragging the layers.
  • For gluten-free version, swap regular brownie mix with gluten-free mix and use gluten-free Rice Krispies.
  • Let bars sit at room temperature for 10 minutes before serving to soften the chocolate layer slightly and enhance flavor blending.
