5 tablespoons unsalted butter, at room temperature
¾ teaspoon pure vanilla extract
¼ teaspoon kosher salt
⅓ cup heavy cream
Instructions
Place the confectioners' sugar, peanut butter, butter, vanilla, and salt in the bowl of an electric mixer fitted with a paddle attachment. Mix on medium-low speed until creamy, scraping down the bowl with a rubber spatula as you work. Add the cream and beat on high speed until the mixture is light and smooth.
Notes
I like to use Skippy Natural Creamy Peanut Butter since it has a nice peanutty flavor and isn't too sweet to begin with. You will be adding plenty of sugary goodness to it. ;)
