Crispy Marshmallow Brownies
1 brownie mix (9×13 size)
1 10-1/2-oz package tiny marshmallows
1-1/2 cups chocolate chips
1 cup peanut butter
1 tablespoon butter
1-1/2 cups Rice Krispies cereal
Prepare the brownie mix according to package directions, making chewy (not cakelike) brownies.
Bake according to directions and top brownies with the marshmallows during the last 3 to 5 minutes of baking or until golden. Cool in the pan on a wire rack.
