Preheat oven according to box directions and prepare a 9×9-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.
