How to Make the Recipe

Step 1: Beat the Butter and Peanut Butter

In a large bowl, beat together the butter and peanut butter using an electric mixer on medium speed until smooth and well combined.

Step 2: Add the Confectioners’ Sugar

Gradually add the confectioners’ sugar, one cup at a time, mixing well after each addition. Continue to beat until the frosting is smooth and fluffy.

Step 3: Add Milk and Vanilla

Add the milk and vanilla flavoring to the mixture. Beat on high speed for about 2 minutes until the frosting becomes light and creamy.

Step 4: Adjust Consistency

If the frosting is too thick, add a bit more milk, one tablespoon at a time, until you reach your desired consistency. If it’s too thin, add a bit more confectioners’ sugar.

Step 5: Use the Frosting

Once the frosting is the desired consistency, spread it on cakes, cupcakes, cookies, or any other baked goods. Use a spatula or piping bag to apply it evenly and smoothly.

Tips for Making the Recipe

Room Temperature Butter: Ensure the butter is at room temperature so it mixes more easily and results in a smooth frosting.
Adjusting Sweetness: If you prefer a less sweet frosting, reduce the amount of confectioners’ sugar slightly or add a pinch of salt to balance out the sweetness.
Peanut Butter Quality: Use smooth peanut butter with a creamy consistency for the best results. Avoid using chunky peanut butter if you want a smooth frosting texture.
Piping Tip: If you plan to pipe the frosting, make sure it’s not too soft. You can refrigerate it for a few minutes to firm it up if necessary.
