Place 1 cup creamy peanut butter and 3 tablespoons butter (softened to room temperature) in a medium mixing bowl.

Sift 2/3 cup powdered sugar into a separate bowl to remove any lumps.
Add the powdered sugar to the peanut butter mixture in two portions, beating on low speed after each addition until incorporated.
Add 1 teaspoon vanilla extract and beat on medium-low speed until the frosting is smooth and spreadable, scraping down the bowl once or twice.

Notes
The key to success is using regular commercial peanut butter rather than natural varieties. Natural peanut butters with separated oils create unstable frosting that won’t set properly. Room temperature butter is crucial for smooth mixing.
