Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 box (18 oz) double chocolate premium brownie mix with chocolate chips
1 large egg
1/3 cup vegetable oil
1/4 cup water
1 jar (7 oz) jet-puffed marshmallow creme
1/3 to 1/2 cup sweetened flaked coconut
2 cups milk chocolate chips
1 cup chunky peanut butter
3 1/2 cups cocoa krispies cereal

Directions

Preheat the oven: Preheat your oven to 325°F (163°C). Lightly grease a 13×9-inch baking pan.
Prepare the brownie base: In a medium bowl, combine the brownie mix, egg, vegetable oil, and water. Stir until fully combined. Spread the brownie batter evenly in the prepared pan.
Bake the brownies: Bake the brownie base in the preheated oven for 35–45 minutes, or until a toothpick inserted into the center comes out clean. Once baked, remove from the oven and let it cool completely.
Add the marshmallow layer: Once the brownie base has cooled, spread the marshmallow creme evenly over the top. Sprinkle with sweetened flaked coconut.
Prepare the topping: In a microwave-safe bowl, melt the milk chocolate chips and peanut butter together in 1-minute intervals, stirring after each, until smooth.
Combine with cocoa krispies: Stir in the cocoa krispies cereal, making sure they are evenly coated with the chocolate-peanut butter mixture.
Spread the topping: Carefully spread the crispy chocolate-peanut butter mixture over the marshmallow fluff layer.
Chill and cut: Cover the pan and refrigerate for at least 2 hours to set. Once chilled, cut the bars into squares and serve.
