This is The Best Peanut Butter Frosting Recipe you're going to find. It's sweet, creamy, peanut buttery PERFECTION made with peanut butter, butter, powdered sugar, vanilla, and heavy cream!
In a large bowl or stand mixer fitted with a paddle attachment, cream together the 1 cup unsalted butter and 1 cup peanut butter, scraping down the sides of the bowl.
Add the 3¼ cups powdered sugar one cup at a time, alternating with 5 tablespoons heavy cream, one tablespoon at a time.
Add in 1 teaspoon vanilla extract and whip on medium-high speed for 2 to 3 minutes until frosting is light and fluffy.
Notes
Add additional cream or powdered sugar as needed to reach the desired consistency. If you prefer your frosting a bit thicker for piping or spreading, simply mix in more powdered sugar, one tablespoon at a time, until it’s just right. If it’s looking a little too thick, add extra heavy cream, tablespoon by tablespoon, until you’ve achieved that perfect, creamy texture.
Frosting can be made with a hand mixer, but it will not be as whipped.
