4. How to Make Homemade Peanut Butter Frosting: Step-by-Step Instructions

This recipe is simple and takes just 10–15 minutes to prepare. The key is beating the ingredients well for a fluffy, smooth finish.

Step 1: Beat the butter and peanut butter

• In a large bowl, combine softened butter and peanut butter.

• Use a hand mixer or stand mixer to beat until light and creamy—about 2–3 minutes.

Step 2: Add powdered sugar

• Gradually add powdered sugar, 1 cup at a time, beating on low speed after each addition.

• Scrape down the sides of the bowl to ensure even mixing.

Step 3: Add vanilla and cream

• Add vanilla extract and 2 tablespoons of cream or milk.

• Beat on medium-high speed until the frosting becomes fluffy and smooth.

• If the frosting is too thick, add more cream 1 tablespoon at a time until it reaches your desired consistency.

Step 4: Taste and adjust

• Taste the frosting. If you prefer it less sweet, reduce powdered sugar slightly.

• Add a pinch of salt if your peanut butter is unsalted to balance the sweetness.

Step 5: Use or store

• Use the frosting immediately to decorate cakes, cupcakes, or brownies.

• Or refrigerate in an airtight container for up to 5 days. Let it come to room temperature and re-whip before using.
