- 1 cup (270 grams) creamy peanut butter
- 1 teaspoon vanilla extract
- 1/8 teaspoon fine salt
- 2 1/2 cups (313 grams) powdered sugar, sifted
Instructions
- In the bowl of an electric mixer fitted with the paddle attachment, beat the butter and peanut butter on medium-high speed until light and fluffy, scraping down the sides and bottom of the bowl as needed.

STORAGE:
- Transfer to an airtight container and store in the fridge for up to a week or in the freezer for up to 3 months. Let come to room temperature and re-whip in the stand mixer until light and fluffy before using. Add a tablespoon or 2 of powdered sugar to thicken if needed.
Notes
- This makes enough frosting for a two layer cake or 24 cupcakes (or 12 cupcakes with a generous amount of frosting).
