Ingredients
Scale
- 1/2 cup unsalted butter, softened
- 1 cup creamy peanut butter
- 2 to 2 1/2 cups powdered sugar
- 1 teaspoon vanilla extract
- 1–2 tablespoons milk (optional, for desired consistency)
Instructions
- Prepare your mixing bowl and paddles of an electric mixer.
- In a large bowl, mix the softened butter and creamy peanut butter until smooth and creamy.
- Gradually add the powdered sugar and vanilla extract. Beat until the frosting is smooth and well combined.
- If the frosting is too thick, add 1–2 tablespoons of milk and mix again until light and fluffy.
- Taste the frosting and adjust sweetness or flavor as needed. Add a pinch of sea salt or a bit more sugar, if desired.
- Use immediately to spread or pipe onto cakes, cupcakes, or other desserts.
Notes
- Use creamy peanut butter for the smoothest consistency. Natural peanut butter may separate and create a grainy texture.
- Adjust the powdered sugar and milk to achieve your preferred sweetness and texture.
- This frosting pairs well with chocolate, banana, or vanilla cakes and cupcakes.
- Can be stored in the refrigerator in an airtight container for up to 5 days. Let it come to room temperature before using.
- Whip the frosting again after refrigerating to restore its fluffiness.
