Description

🥜 Enjoy a light and creamy peanut butter frosting that adds rich flavor without heaviness.
🎂 Perfect for frosting cupcakes, cakes, or desserts with a fluffy and smooth texture.


Ingredients

Scale

1 cup (226 g) unsalted butter, softened to room temperature
1 cup (245270 g) creamy peanut butter (processed type recommended; avoid natural peanut butter that separates)
1 to 3 cups (114375 g) powdered sugar (adjust for desired frosting thickness)
1 teaspoon vanilla extract (or vanilla bean paste)
½ teaspoon salt (omit if using salted butter)
2 to cup (2 tablespoons to 80 ml) milk or heavy cream, room temperature (adjust for texture)


Instructions

1. In a large bowl, beat the softened butter and creamy peanut butter together with an electric mixer until smooth and well combined.
2. Gradually add powdered sugar, about one-third cup at a time, mixing on low speed and scraping the sides and bottom of the bowl as needed.
3. Stir in vanilla extract and salt.
4. Add milk or heavy cream while mixing on low speed.
5. Increase mixer speed to high and beat for 30 seconds to 3 minutes until light, fluffy, and creamy.
6. Adjust frosting thickness by adding additional powdered sugar for stiffer consistency or more milk/heavy cream for a thinner one.
7. Use immediately or store in an airtight container.

Notes

🥄 Processed creamy peanut butter delivers the best texture; avoid natural types that separate.
🧈 Make sure butter is softened but not melted to keep frosting smooth.
❄️ Store leftover frosting in the fridge for up to a week or freeze for up to three months; re-whip before use.
