Spread marshmallow frosting over the cooled brownies.
Add the chocolate chips and peanut butter to a mixing bowl and microwave in 30 second bursts until melted. Stir well.

Notes

We highly recommend using our recipe for homemade brownies, but a box mix will work as well. Just be sure to use a family size mix that's meant to be baked in a 9x13 (or make a double batch of regular brownie mix and add it all to the one pan) or your brownies will be too thin and the ratio of marshmallow and topping will be off.

The marshmallow frosting is fairly sweet. Adding a pinch of salt helps to balance it out a bit.
