How to Make Ultimate Rich Peanut Butter Marshmallow Crispie Brownie Bars

  1. Preheat your oven to the temperature specified on your brownie mix box. Prepare a 9x13 inch baking pan by greasing and flouring it.
  2. Prepare the brownie batter according to the instructions on the brownie mix box. Pour the batter into the prepared baking pan.
  3. Spread the prepared brownie batter evenly in the baking pan.
  4. In a medium saucepan, melt the peanut butter and marshmallows over low heat, stirring constantly until smooth and combined.
  5. Pour the peanut butter marshmallow mixture evenly over the brownie batter.
  6. In a separate bowl, combine the Rice Krispies cereal and melted butter until the cereal is evenly coated.
  7. Sprinkle the Rice Krispies cereal evenly over the peanut butter marshmallow layer.
  8. Bake for 50 minutes, or until the brownie is cooked through and the topping is golden brown. Insert a toothpick into the center; if it comes out with moist crumbs, it's done.
  9. Let the bars cool completely before cutting into squares. This allows the bars to set up and makes them easier to cut and serve.
  10. Once cool, cut into squares and enjoy your irresistible Peanut Butter Marshmallow Crispie Brownie Bars!
