The peanut butter frosting is to die for. Most of the sweetness comes from the frosting which balances out with the brownie which is relatively unsweet. Only downside for me was the brownie was a bit dry.

The peanut butter topping is amazing! It tastes like peanut butter whipped cream. However, I didn't love the brownie. I don't like it baked in the jelly roll pan. It only took 20 minutes to bake and the outside edges had to be cut off because they were so hard. I lined the pan with parchment paper, which made them easy to remove from the pan. I think I'll bake the brownie in a normal rectangle cake pan next time.
