Equipment

1 9x13-inch pan

Ingredients

1 box brownie mix plus ingredients called for on the box mix
3 cups mini marshmallows
12 ounces semi-sweet chocolate chips (2 cups)
1 cup creamy peanut butter
3 cups Rice Krispies cereal

Instructions

Prepare the brownie mix according to the box instructions. (Be sure that you’re preparing it in a 9×13 pan – some brownie mixes these days only fit an 8×8 square pan.)
1 box brownie mix
Remove the brownies from the oven and immediately put sprinkle the marshmallows over-top; return to the oven for 3 minutes.
3 cups mini marshmallows
While the brownies cool a bit, make the topping.
In a microwave-safe bowl, stir together the chocolate chips and peanut butter; microwave in 30 second intervals, stirring after each one, until smooth.
12 ounces semi-sweet chocolate chips, 1 cup creamy peanut butter
Add the Rice Krispies stir until evenly coated.
3 cups Rice Krispies cereal
Carefully spoon the mixture over the marshmallow-covered brownies and use a rubber spatula or knife to spread it out evenly.
Cool the bars completely before cutting and enjoy! (You can put them in the fridge to help set the bars more quickly!)

Notes

Ingredient Substitutions

Peanut Butter - Use almond butter or sunbutter in place for a good peanut-free option.
Mini Marshmallows - You can cut regular-sized marshmallows in half to cover the brownies or use marshmallow creme (though it'll much a much softer texture and less chewy).

Storage

The brownies can be stored at room temperature or in the fridge (I love the chewiness of the refrigerated brownies!). They can also be kept in the freezer to store for a longer period of time.
