How to Make the Recipe

Step 1: Cream the Butter and Peanut Butter

In a mixing bowl, combine the butter and peanut butter. Using an electric mixer or hand mixer, beat them together until the mixture is smooth and well combined.

Step 2: Add the Sugar and Milk

Gradually add the confectioners sugar, one cup at a time, alternating with the milk. Continue mixing until the frosting reaches your desired consistency.

Step 3: Add the Vanilla

Stir in the vanilla flavoring, mixing until well incorporated.

Step 4: Adjust the Consistency

If the frosting is too thick, add more milk, one tablespoon at a time, until you achieve the perfect spreadable texture. If it’s too thin, add a little more powdered sugar until it thickens to your liking.

Step 5: Frost Your Dessert

Spread the peanut butter frosting generously on your cooled cake or cupcakes. Use a spatula or piping bag to decorate your dessert as desired.

Tips for Making the Recipe

Room Temperature Butter: Ensure that the butter is softened to room temperature before mixing for a smooth and creamy consistency.
Adjust Consistency: If you want a stiffer frosting, reduce the amount of milk. For a softer frosting, add more milk as needed.
Chill for Stability: If you find the frosting is too soft to hold its shape, chill it for about 30 minutes to firm it up before applying to cakes or cupcakes.
Peanut Butter Choice: Use smooth peanut butter for a creamy texture, but if you prefer a bit of crunch, try using crunchy peanut butter instead.
