Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1 cup (250 g) creamy peanut butter

1/2 cup (115 g) unsalted butter, softened

2 cups (240 g) powdered sugar, sifted

1–2 tbsp heavy cream or milk (adjust for consistency)

1 tsp vanilla extract

Directions

Cream Butter and Peanut Butter:
In a large mixing bowl, I beat the softened butter and peanut butter together with an electric mixer until the mixture is smooth and creamy.

Add Powdered Sugar:
Gradually, I add the powdered sugar, about 1/2 cup at a time, mixing well after each addition until fully incorporated.

Adjust Consistency:
I add 1 tablespoon of heavy cream or milk at a time, beating after each addition until the frosting reaches a thick but spreadable consistency.

Add Vanilla:
Finally, I mix in the vanilla extract and beat the frosting for another 1–2 minutes to ensure it’s fully combined and fluffy.

Use or Store:
I spread or pipe the frosting onto my dessert immediately. If I’m not using it right away, I store it in an airtight container in the refrigerator for up to 3 days. Before using, I let it soften at room temperature.

Servings and Timing

Servings: Makes enough to frost a standard 9-inch cake, 12 cupcakes, or a batch of brownies.

Prep Time: 10 minutes

Variations

Chocolate Peanut Butter Frosting: Add 1–2 tablespoons of cocoa powder when mixing in the powdered sugar.

Sweet and Salty: Sprinkle a pinch of sea salt into the frosting for a sweet-savory flavor.

Honey Peanut Butter Frosting: Substitute part of the powdered sugar with 2 tablespoons of honey for a natural sweetness.

Vegan-Friendly: Use dairy-free butter and plant-based milk to make it vegan.

Crunchy Twist: Mix in a handful of chopped peanuts for added texture.

Storage/Reheating

Storage: I store leftover frosting in an airtight container in the refrigerator for up to 3 days.

Reheating: When I’m ready to use it, I let it sit at room temperature until it softens, then give it a quick stir or beat with a mixer to restore its creamy texture.
