Ingredients
  

  • 1 (18-ounce) box brownie mix + ingredients listed on the box
  • 1 1/2 cups semi-sweet chocolate chips
  • 1/2 cup creamy peanut butter
  • 1/4 cup unsalted butter
  • 2 1/2 cups mini marshmallows divided
  • 1 cup dry roasted, salted peanuts divided

Instructions
 

  • Preheat oven according to box directions and prepare a 9x9-inch pan as instructed. Mix and bake the brownies as directed. Let cool in the pan for 15–20 minutes.
  • In a medium saucepan over medium-low heat, combine the chocolate chips, peanut butter, and butter. Stir until melted and smooth. Remove from heat and let sit for 5 minutes.
  • Fold in 2 cups of marshmallows and 3/4 cup of peanuts until evenly combined.
  • Spread the topping over the slightly cooled brownies.
  • Sprinkle with the remaining 1/2 cup of marshmallows and 1/4 cup of peanuts, pressing gently to help them stick.
  • Let cool completely at room temperature, then refrigerate for 2-3 hours before cutting into squares.

Notes

  • Refrigerating before slicing helps the topping set, making cutting cleaner.
  • Store in an airtight container for up to 3-4 days.
  • Wrap individual squares tightly and place in an airtight container or freezer bag. Freeze for up to 3 months.
