Creamy Peanut Butter Frosting

By norsegal8

The frosting can be made up to 24 hours in advance and refrigerated in an airtight container. When ready to frost, place frosting in a microwave-safe container and warm briefly on high power until just slightly softened, 5 to 10 seconds. Once warmed, stir until creamy.

Ingredients

• 1/2 cup granulated sugar
• 2 large egg whites
• 1/8 teaspoon table salt
• 12 tablespoons (1 1/2 sticks) unsalted butter, softened and cut into 1-tablespoon pieces
• 1/2 teaspoon vanilla extract
• 2/3 cup creamy peanut butter
• 1/2 cup chopped peanuts

Preparation

Step 1

1. Combine sugar, egg whites, and salt in bowl of stand mixer; place bowl over pan of simmering water. Whisking gently but constantly, heat mixture until slightly thickened, foamy, and registers 150 degrees on instant-read thermometer, 2 to 3 minutes.

2. Place bowl in stand mixer fitted with whisk attachment. Beat mixture on medium speed until consistency of shaving cream and slightly cooled, 1 to 2 minutes. Add butter, 1 piece at a time, until smooth and creamy. (Frosting may look curdled after half of butter has been added; it will smooth with additional butter.) Once all butter is added, add vanilla and peanut butter; mix until combined. Increase speed to medium-high and beat until light, fluffy, and thoroughly combined, about 30 seconds, scraping beater and sides of bowl with rubber spatula as necessary.
