Keto Peanut Butter Mousse

In a large mixing bowl, beat together the peanut butter, cream cheese, powdered sugar, and vanilla extract and set aside. In a separate mixing bowl, beat together the heavy cream until stiff peaks form. 

Gently beat through ¼ of the whipped heavy cream into the peanut butter mixture. Fold through another ½ of the cream and mix well. Add the remaining cream until combined.
