For anyone who loves Reese's peanut butter cups as much as I do, you will LOVE these brownies.
1 box brownie mix (plus the ingredients it calls for in the box)
1/2 cup butter (softened)
3/4 cup creamy peanut butter
2 cups powdered sugar
2 teaspoons milk
1 cup chocolate chips
Prepare and bake brownies as instructed on the box.
Beat together the butter, peanut butter, powdered sugar, and milk and spread on top of cooled brownies.
In a microwave safe bowl, melt the chocolate chips and butter for 15-30 minutes, stirring in between increments until melted. Pour and spread over top of the peanut butter layer.
