This peanut butter frosting recipe is light, creamy, and it has just the right amount of sweetness. This recipe is the perfect frosting for brownies and chocolate cake!
I love the peanut butter and chocolate combination, especially when it comes to brownies or deep, rich chocolate cake. Unfortunately, a lot of recipes that I’ve tried for peanut butter frosting were just way too heavy and overly sweet.
Consequently, I decided to come up with my own recipe by using my favorite cream cheese frosting as a guide. I took out a lot of the heaviness from traditional buttercream recipes by using a little heavy whipping cream rather than all butter. As a result, this peanut butter frosting ended up being light, fluffy, and ah-amazingly delicious!
Peanut Butter Frosting for Brownies
My brother Jeff has an obsession with peanut butter. He puts it in his protein shakes, on his ice cream, puts a scoop of it on his cookies, and who knows what else he adds it to! In addition to loving peanut butter, he also loves brownies. Because of his two loves, I knew I needed to make a Peanut butter frosting for brownies to feed his obsession.
This peanut butter buttercream is light, fluffy, and oh so delicious. Add the peanut butter frosting to my Triple Chocolate One Bowl Brownies and you will not be sorry! I now understand his love of peanut butter and brownies after combining these two recipes and am now a little obsessed myself.
