Ingredients

• Unsalted butter at room temperature: This forms the base and adds creamy structure Choose the highest quality butter you can find for best flavor
• Creamy peanut butter: Gives that signature nutty taste Smooth style blends seamlessly Avoid natural peanut butter for the best texture
• Powdered sugar: Adds sweetness and thickens the frosting Sift if you want a smoother finish
• Vanilla extract: Rounds out the flavors Pure vanilla offers the richest aroma and taste
• Milk or heavy cream: Used just as needed to loosen the frosting Go for heavy cream for extra richness or whole milk for a lighter result

Instructions

Prepare the Butter and Peanut Butter:

Let butter sit out until soft to the touch This step is key to a smooth and fluffy frosting Place the butter and peanut butter in a large mixing bowl

Beat Until Fluffy:

Using an electric mixer beat together butter and peanut butter on medium speed for about one minute Scrape down the sides of the bowl The mixture should look light and airy by the end

Sweeten and Add Flavor:

Adjust Consistency:

If frosting is too stiff add milk or cream one tablespoon at a time Beat after each addition until it reaches your desired pillowy texture It should be soft enough to spread but hold peaks if you want to pipe it
