Recipe: Peanut Butter Brownies

These guys are Reeses in brownie form -- chewy chocolate-peanut butter brownies topped with peanut butter frosting. A few weeks ago a peanut butter-frosted chocolate cupcake inspired me to make something similar. But then I found and began to salivate over how Evil Shaningan's added peanut butter to her chocolate brownie recipe, only I wanted to take the blog's advice to add peanut butter frosting. And this buttercream+pb frosting recipe on AllRecipes.com looked just right.  

I went with a trustworthy box mix (whose batter just tastes so good) and took this brownie experiment to visit a friend for the weekend. We had no problem polishing them off and deciding that both of us would have to make them again (and probably again and again).

Peanut Butter Brownies

1 box brownie mix for 13x9 pan

1/3 cup peanut butter

Peanut Butter Frosting (recipe below)

Prepare brownies according to package instructions, adding peanut butter to the mixture. Bake as directed. When brownies cool, spread with frosting.

Peanut Butter Frosting

1/4 cup butter, softened

1/2 cup creamy peanut butter

1-2 tablespoons milk, or as needed

1 cups confectioners' sugar

Place the butter and peanut butter into a medium bowl, and beat with an electric mixer. Gradually mix in the sugar, and when it starts to get thick, incorporate milk one tablespoon at a time until all of the sugar is mixed in and the frosting is thick and spreadable. Beat for at least 3 minutes for it to get good and fluffy.
