For this recipe, I used heavy cream, softened cream cheese, lemon zest, and low carb sweetener.

I used my stand mixer to get the heavy cream whipped to stiff peaks.  Then, I scraped it into a separate bowl and set it aside.  You could also whip this by hand with a whisk or use a hand mixer.

I then beat the softened cream cheese, lemon zest, and the sweetener until it was nice and smooth.

I poured the whipped cream into the stand mixer bowl with the cream cheese and I gently folded it with a spatula to get it half way incorporated.  Then used the stand mixer with the whisk and I beat the mixture until it was completely smooth.  Now we have no bake keto cheesecake fluff!

I scraped it all into a piping bag to get it into the glasses nice and pretty.  This is totally optional, but it does make it nice if you were serving the keto cheesecake fluff to guests.

For the crumble of this low carb cheesecake mousse, I used the Atkins Lemon Bar!  I chopped it up into chunks and it was the perfect addition to this recipe.  My Keto Granola would be equally amazing as a topping for this dessert.

I chopped up my crumble and I put some into the bottom of the glasses, followed by keto no bake cheesecake, then more crumble, cheesecake fluff, and finally, the crumble on top.

  • Crumble: You can choose any low carb bar you like...I like the Lemon Atkins Bar.  Here is a list of other keto granola bars.
  • Softened Cream Cheese: Make sure your cream cheese is really soft or your mousse will be lumpy.
  • Lemon Zest: If you prefer, you could make this a vanilla mousse by eliminating the lemon zest and adding 1 teaspoon of vanilla extract.

    Loved this! Totally satisfied my “sweet” tooth and my love for cheesecake. My husband and son who are not in on this low car/keto life loved it too.

    I love mousse because it’s so much lighter than cheesecake. It’s perfect to finish with when having guests for dinner. And lemon is one of my favorite flavors. This looks amazing and now you’ve got me curious about the Atkins bars so I’ll have to go buy some for myself.
