Make brownies from your favorite mix, cool completely. Frost with:
Fluffy Peanut Butter Frosting
- 1/2 cup butter, softened
- 1 cup creamy peanut butter
- 2 cups confectioners' sugar
- 3 tablespoons milk, or as needed
- Cream the butter and peanut butter together till well-blended (and try to ignore the fact that you are about to eat all of that fatty buttery goodness). Add in the sugar gradually, mixing well. Finally, add in the milk. Mix just till blended and creamy. If you overmix, it may start to look grainy. Supposedly you can fix that by microwaving it for a couple seconds and then mixing it a bit more.
