Step 1

In the bowl of a stand mixer fitted with the paddle attachment, place the peanut butter and butter. Sift the sugar into the bowl. Add the vanilla extract and salt.

Step 2

Starting on low and gradually increasing (to prevent the sugar from covering your kitchen) the speed to medium-high, beat the ingredients until light and fluffy, scraping the sides and bottom of the bowl as needed, about 2 to 3 minutes. Beat in the heavy whipping cream until it is fully incorporated, about 30 seconds.
