Grab a big bowl and mix the batter following the brownie box instructions. Pour it into the prepped pan and bake it for 30-40 minutes until it's done. Check your box for the baking time for a 9×9 pan—it’s usually the same. Once it’s out of the oven, let it cool all the way.

Spread the peanut butter stuff over the cooled brownies. Smooth it out nicely, then pop it in the fridge until it sets. Give it at least 2 hours to chill.
