  2. Then the peanut butter and vanilla extract, mix until smooth and creamy. Add more of the heavy cream if needed, to get your desired consistency.
  3. Add the frosting to a piping bag fitted with the tip of your choice (ziplock bag with the tip cut off will work too) and frost your cooled cake or cupcakes!
