Why This Recipe Works
The secret to perfect peanut butter frosting lies in using the right type of peanut butter and achieving the proper butter-to-sugar ratio. Regular creamy peanut butter (like Jif) provides stability, while the butter adds richness and helps create that smooth, pipeable texture. Sifting the powdered sugar eliminates lumps, ensuring a silky finish every time.
Ingredients
- Creamy peanut butter – Provides the rich, nutty base flavor and creamy texture
- Butter – Adds richness and helps create smooth, pipeable consistency
- Powdered sugar – Sweetens and thickens the frosting to proper spreading consistency
- Vanilla extract – Enhances the overall flavor and adds depth
How to Make Peanut Butter Frosting
- Put the peanut butter and butter in a bowl and beat with an electric stand mixer until smooth.
- Sift confectioners’ sugar to remove lumps.
- Add powdered sugar and vanilla to the peanut butter mixture.
- Beat at medium-high speed until combined and smooth. Be sure to scrape the sides of the bowl a few times while mixing.
- Spread the frosting on cake, cupcakes, or brownies.
How Much Will This Recipe Make?
When making a recipe it’s always nice to know how much to expect beforehand. For this recipe, you will be able to cover:
- 12 to 15 cupcakes
- A 9×13 inch pan
- A double layer round cake
So based on how many cupcakes you need or how many layers of cake you are making you can easily double the recipe if you are making larger quantities. Plus, if you like to layer your cake or cupcakes a little thicker I take that into consideration too.
Storage & Reheating Instructions
- Refrigerator Storage: Store in an airtight container for up to 1 week. Frosting will firm up when chilled.
- Bringing to Room Temperature: Let stand at room temperature for 30-60 minutes before using. Stir gently to restore smooth texture.
- Freezing: Can be stored in the freezer for up to 3 months. Thaw overnight in the refrigerator, then bring to room temperature and re-whip if needed.
