The beauty of these brownies (other than being ridiculously delicious) is that they are really simple. They use your favorite brownie recipe, whether it be boxed or homemade, and then you smother them in this dense, fudgey peanut butter frosting. This is not the type of frosting you want to ice your cupcakes with because after a few hours in the fridge, it truly takes on a thick fudge like consistency.
I recently made these for a family get together, and despite being over 10 different desserts there, these were devoured. I left a few stragglers in our fridge, and Ryan and I feasted on them with our coffee for a few days. A day after they were all gone, Ryan was already asking when I was making them again. Luckily for him, but unfortunately for my waistline, I have all the ingredients hiding out in our pantry right now. I think another batch is in order very soon!
Chocolate Brownies with Peanut Butter Fudge Frosting
1 batch of brownies (I love the Pillsbury Chocolate Fudge Family Size)
1 cup peanut butter
1 stick unsalted butter, room temperature
2 cups powdered sugar
1 tsp. vanilla extract
Prepare brownies as directed and then let cool completely.
To make frosting: In the bowl of a stand mixer, cream together your butter and peanut butter until smooth. Slowly add in powdered sugar, 1/2 cup at a time. Mix until incorporated after each addition. Add vanilla extract and beat for another 1-2 minutes. Frosting should be thick, but spreadable. Spread frosting evenly over your cooled brownies and refrigerate. These get fudgier then longer they are in the fridge, so keep them in there as long as you can. I recommend at least 3 hours. They are even better the following day, so they are great to make the night before!
