Make the Fluff

  • Add the heavy cream to a stand mixer and whisk until stiff peaks are formed. You can also use a hand mixer or whip by hand with a whisk.
  • Remove the whipped cream to a separate bowl and set aside
  • Add the softened cream cheese, zest, and sweetener to the stand mixer bowl and beat until smooth.
  • Pour the whipped cream into the stand mixer bowl with the cream cheese.  Stir gently with a spatula until it is halfway incorporated.  Use the stand mixer to finish whipping until smooth.
  • Serve with your favorite topping. See notes below for flavor mix-ins.



  • NUTRITION: Listed nutrition is for just the no bake cheesecake mousse.
  • SWEETENER: This recipe works with either powdered Swerve or Powdered Lakanto sweetener.  
  • TOPPINGS: My favorite is my keto granola
    • toasted coconut
    • chopped berries
    • chocolate chips
  • SOFTENED CREAM CHEESE: Make sure your cream cheese is really soft or your mousse will be lumpy.
    • If you prefer, you could make this a vanilla mousse by eliminating the lemon zest and adding 1 teaspoon of vanilla extract.
    • replace the lemon zest with PB2 for a peanut butter fluff
    • replace the lemon zest with 1 teaspoon of cocoa powder for a chocolate keto fluff
  • STORING: This will keep in the refrigerator in an air tight container for up to a week.
