Begin by placing the room temperature unsalted butter and the creamy peanut butter into a mixing bowl. Using an electric mixer on medium speed, beat the mixture for about 1 minute. Your goal is to achieve a whipped and fluffy consistency.

Next, you’ll want to add the powdered sugar and the vanilla extract into the bowl. Beat this mixture on low speed for 1-2 minutes. Be sure to scrape down the sides of the bowl as needed to incorporate all the ingredients fully.

If your frosting seems a bit thick, not to worry! Just add a dash of milk or heavy cream, about a tablespoon should do. Continue beating until you achieve that creamy and smooth texture that we all adore.

Now comes the fun part! You can spread or pipe your heavenly peanut butter frosting onto cakes, cupcakes, or brownies as desired. Take a moment to enjoy the delightful nutty flavor that is simply out of this world!
