🧾 Ingredients
- 1 cup creamy peanut butter

- 2 cups confectioners’ sugar (powdered sugar)
- 3–4 tablespoons milk or water
- 2 teaspoons vanilla extract
🥣 Instructions
Step 1: Cream the Butter and Peanut Butter
In a large mixing bowl, combine the softened butter and creamy peanut butter. Beat with a hand mixer or stand mixer on medium speed until the mixture becomes smooth, creamy, and well blended.
Step 2: Add the Powdered Sugar
Gradually add the confectioners’ sugar one cup at a time. Continue mixing slowly so the sugar incorporates smoothly without forming lumps.
Step 3: Add Vanilla and Liquid
Add the vanilla extract and 3 tablespoons of milk or water. Beat the frosting until light and fluffy.
Step 4: Adjust Consistency
If the frosting is too thick, add the remaining 1 tablespoon of milk gradually until the frosting reaches your desired spreading consistency.
Step 5: Frost Your Dessert
Use the frosting immediately to spread on cakes, cupcakes, brownies, or cookies. It can also be piped using a piping bag for decorative swirls.
🍰 Preparation Method
This frosting uses the creaming method, which is commonly used for buttercream-style frostings.
- Fat base creation – Peanut butter and butter are creamed together to form a rich base.
- Sweetening – Powdered sugar is incorporated gradually to create sweetness and structure.
- Flavoring – Vanilla enhances the nutty aroma.
- Texture adjustment – Milk or water is added to make the frosting silky and spreadable.
This method creates a smooth, stable frosting perfect for decorating and layering cakes.
