Homemade Peanut Butter Frosting
Creamy peanut butter frosting made with butter, peanut butter, powdered sugar, and vanilla for cakes, cupcakes, and brownies.
Equipment
- Hand mixer or stand mixer
- Large mixing bowl
- Rubber spatula
- Fine mesh sieve
Ingredients
Main Ingredients
- ½ cup unsalted butter softened
- 1 cup creamy peanut butter
- 2 cup powdered sugar sifted
- 1 tsp vanilla extract
- 2 tbsp whole milk add 1 tablespoon at a time as needed
Instructions
Cooking
- Cream the base. Beat the butter and peanut butter on medium speed for 2 minutes until smooth, pale, and creamy.
- Add the sugar. Beat in the powdered sugar on low speed, 1/2 cup at a time, for about 2 minutes until combined.
- Flavor and loosen. Add the vanilla and 1 tablespoon of milk, then whip for 1 minute. Add the second tablespoon only if the frosting is stiff.
- Frost. Use right away on cooled cakes, cupcakes, or brownies. If it is too soft, chill for 10 minutes and stir.
Notes
Substitutions: Crunchy peanut butter adds texture, and cocoa powder turns this into a chocolate version.
Tips: Soften the butter for about 30 minutes and sift the sugar for a smooth finish.
Storage: Refrigerate up to 1 week or freeze up to 3 months. Stir before using.
