This smooth, fluffy frosting is chock-full of creamy peanut butter and the perfect topper for cakes and cupcakes.

Ingredients

• 12 tablespoons (1 1/2 sticks) Unsalted Butter
• 1 (15- to 16-ounce) jar Smooth Peanut Butter (about 1 1/2 cups), preferably Skippy or Jif
• 1 cup Powdered Sugar
• 1 teaspoon Vanilla Extract

Procedure

1. Cut 1 1/2 sticks unsalted butter into 6 pieces.
2. Place the butter, 1 (15- to 16-ounce) jar smooth peanut butter, and 1 cup powdered sugar in the bowl of a stand mixer (or large bowl if using an electric hand mixer).
3. Let sit until the butter is room temperature.
4. Add 1 teaspoon vanilla extract and beat with the paddle attachment on low speed until incorporated, about 30 seconds.
5. Increase the speed to medium and beat until fluffy and lightened in color, about 3 minutes more.

Cook’s Notes

Peanut butter: The smoother the peanut butter, the smoother the frosting. I like Skippy Natural, which has an ultra-smooth texture.

Storage: Leftover frosting can be stored in an airtight container at room temperature for up to 2 days.
