Start by gathering your ingredients. You’ll need butter, creamy peanut butter, milk, and powdered sugar. It’s essential to have your butter at room temperature to ensure it mixes well. If it’s too cold, you won’t achieve that creamy texture.
In a large bowl, use an electric mixer to combine the room-temperature butter and peanut butter. Begin mixing at a low speed to avoid a mess, then gradually increase it. Blend until smooth and well-combined. You'll want to see a creamy and fluffy mixture that’s inviting to taste.
Next, add in the milk. Start with 1/4 cup and mix it in. This will help to loosen the mixture slightly, allowing you to add the powdered sugar more easily. If you find the frosting is too thick, don’t hesitate to add a little more milk to achieve the right consistency.
Once the milk is integrated, slowly incorporate the powdered sugar. Gradually add it in, mixing on low speed to prevent a cloud of sugar from filling your kitchen. As you add the sugar, you’ll notice the frosting thickening and becoming sweeter.
Continue to mix until all the powdered sugar is fully combined. Scrape down the sides of the bowl as needed to ensure everything is well-mixed. The frosting should be fluffy and have a beautiful pale yellow color, indicating that it’s perfectly mixed.
At this point, check the consistency. If it seems too thick, add a splash of milk and blend again. You want a frosting that is spreadable but still holds its shape when piped or spread on a cake or cupcakes.
Once you achieve the desired consistency, taste the frosting! You should get a delightful mix of sweetness and that unmistakable peanut butter flavor. Adjust sweetness or richness according to your preference if necessary.
Your Creamy Peanut Butter Frosting is now ready to use! You can frost a two-layer cake or spread it onto 24 cupcakes. This frosting is versatile and can complement any dessert you choose!
Remember to save any leftovers in an airtight container. It can be stored in the refrigerator for up to a week. Just give it a good stir before using it again!
