This creamy and rich peanut butter frosting is perfect for cakes, cupcakes, or as a sweet spread.
In a mixing bowl, combine the creamy peanut butter and softened butter.
Ensure both ingredients are at room temperature for easier mixing.
Using an electric mixer, beat the mixture until smooth and well combined.
Start at a low speed to avoid splattering, then increase to medium.
Gradually add the powdered sugar, mixing on low speed until fully incorporated.
Add the sugar in small batches to prevent a cloud of sugar dust.
Add the milk one tablespoon at a time, mixing until the frosting reaches your desired consistency.
If the frosting is too thick, add a bit more milk; if too thin, add a little more powdered sugar.
Use the frosting immediately or store it as needed.
Spread the frosting on your dessert with a spatula for a smooth finish.
