Easy Peanut Butter Buttercream

Ingredients

8 tablespoons unsalted butter, softened½ cup smooth peanut butter (don't use old-fashioned or natural brand)¾ cups confectioners' sugar Pinch table salt ½ teaspoon vanilla extract 1 tablespoon heavy cream

Before You Begin

Any of the buttercream frostings (see related recipes) can be made ahead and refrigerated; if refrigerated, however, they must stand at room temperature to soften before use. If using a hand-held mixer, increase mixing times significantly (at least 50 percent). This recipe can be doubled to make enough for a two-layer cake.

Instructions

  1. In standing mixer fitted with whisk attachment, beat butter and peanut butter at medium-high speed until smooth, about 20 seconds. Add confectioners' sugar and salt; beat at medium-low speed until most of the sugar is moistened, about 45 seconds. Scrape down bowl and beat at medium speed until mixture is fully combined, about 15 seconds; scrape bowl, add vanilla and heavy cream, and beat at medium speed until incorporated, about 10 seconds, then increase speed to medium-high and beat until light and fluffy, about 4 minutes, scraping down bowl once or twice.

Why This Recipe Works

Traditional buttercream frosting involves heating eggs and sugar over a pan of simmering water and whipping in butter while carefully monitoring for the correct temperature. Our easy buttercream recipe is equally delicious and much less fussy. Creamy peanut butter add a bold peanut flavor while maintaining the frosting's creamy texture.
