This content originally appeared on Low Carb Yum. Republished with permission.

Rich cream cheese, luscious heavy whipping cream, and the perfect dash of vanilla and lemon extracts sweetened just right with keto sweetener come together in this simple yet decadent keto cheesecake mousse. It’s quick and easy to prepare!

You can probably tell from my previous recipes that I like low-carb mousse recipes (hellooooo chocolate mousse). They’re sweet and fluffy and make the perfect light dessert after dinner!

So I’m excited to add another one to the list with this delicious keto cheesecake fluff.

I know that starting a keto diet can be tough, especially when you have a sweet tooth. That’s why I love finding recipes like this one that satisfy cravings without derailing your progress.

This super yummy dessert whips up so quickly, just like my chocolate avocado pudding.

So, if you like the taste of sugar-free cheesecake, then you are going to love the flavor of this keto mousse.

Why Should I Make This Keto Cream Cheese Dessert?

This sugar-free cheesecake mousse is great because it ends up being much healthier than regular cheesecake.

This dessert doesn’t have a crust, meaning gone are the calories and fat of melted butter and the heaviness of an almond flour crust. Instead, you get all the deliciousness in a light and airy form.

Bonus: since this is a keto-friendly dessert, it’s also gluten-free! So you can indulge without any worries.

The best part is that it’s one of the quickest low-carb desserts you can ever make. Plus, it only uses six ingredients and a single bowl (instead of a springform pan!) that you likely already have.

Ingredients Needed

Ready to make this delicious dessert? Here’s a list of everything you’ll need to make this keto cheesecake fluff:

How To Make This Easy Keto Cheesecake Fluff

This is the easiest keto dessert with cream cheese you have ever made!

The entire recipe, along with the recipe steps, is in the printable recipe card at the bottom of this post.

Keep reading – I have some important tips, and helpful pictures of the process of making the keto fluff that I’m sure will help you out.

Step 1: Whip softened cream cheese

For this recipe, you start by putting a block of cream cheese in a mixing bowl.

To soften the cheese, I put it in the microwave for about 30 seconds and then stir it up with a fork. It’s important to start with softened cream cheese, otherwise you could end up with lumps.

Step 2: Add sweeteners and extracts

At this point, it’s time to add sweetener and flavor extracts. I love using a mix of erythritol and stevia along with stevia extract powder. But feel free to use the keto sweetener(s) of your choice.

You can always taste test to get the amount right of sweetener. The recipe needs about ½ to ¾ of sugar replacement, depending on how sweet you like it.

For the extracts, I use vanilla and lemon. However, feel free to experiment with different ones or lemon juice to change up the taste!

Step 3: Mix in whipped cream for a light keto fluff

The sweetened cream cheese mix is excellent by itself before adding the whipped cream.

However, to get the airy texture, you’ll want to incorporate the cream by folding it in first, which prevents too much deflation. Then, the entire mixture is whipped together with an electric mixer.

Optional: Fold In ingredients for a keto cheesecake mousse

No, it’s not like folding a shirt. You have to take your time and be gentle!

To fold the whipped cream into the cream cheese, take your spatula and lightly bring the cream cheese from the sides of the bowl on top of the cream cheese in the middle.

Folding is basically a lighter version of mixing. You are still combining the whipped cream with the cream cheese, but you are doing it gently.

Step 4: Chill and serve

Now it’s time to let the flavors meld together in the fridge.

I recommend chilling this dessert for at least two hours before serving, but you can also prepare it a day ahead of time.

Once chilled, you can pipe or spoon the mousse into individual serving dishes right away or do it after the mousse has chilled in the refrigerator. I prefer chilling the mousse first and then putting it into serving dishes.

I recommend using a pastry bag to pipe the mousse into single servings to give it a pretty look, but scooping it out with a spoon is okay too!

What To Serve With Keto Cheesecake Fluff

There really are SO many different ways you can serve this dessert!

While it is absolutely delicious on its own, you could dress this one up with some sweet cinnamon almond meal sprinkles to mimic graham cracker crumbs and add some drizzled strawberry sauce for a strawberry cheesecake parfait.

Maybe you want to put some chocolate shavings on top of the sugar-free cheesecake keto mousse. Or, maybe you prefer a low-carb fruit sauce, like this sugar-free blueberry syrup.

There are so many different ways to go about it!

For a quick topping, I sprinkled sugar-free chocolate chips (ChocZero is my absolute fav!) on each serving. Another option would be to double the recipe and use it as a light and airy no-bake cheesecake filling.

You can even blend it with another low-carb mousse (this keto white chocolate mousse sounds amazing) for an easy layered dessert!

How To Store Keto Cheesecake Mousse

Just like other low-carb cream cheese desserts, this needs to be refrigerated. Store it in an airtight container in the refrigerator. It will stay fresh for about 4-5 days.

Frequently Asked Questions

Here are the questions I hear the most about my keto cheesecake fluff recipe. If you don’t see your questions answered here, please leave them for me in the comments below. I try to respond to every question.

Is it okay to use a stand mixer for this recipe?

Absolutely! A stand mixer works just as well as an electric hand mixer. Just follow the same steps outlined in this post with your stand mixer.

Can I freeze a low-carb dessert with cream cheese?

Yes, you can, but the texture will change.

Instead of being light and fluffy, it will become a hard block, kind of like a solid block of ice cream.
As it thaws, it will be easier to eat, but it still won’t have the same fluffy texture.

Just a fair warning!

How do I make a keto cheesecake mousse with chocolate?

To add some chocolate flavor to this keto cream cheese dessert, you can mix in some unsweetened cocoa powder or sugar-free chocolate chips. You could also drizzle melted sugar-free chocolate on top.

For an even easier option, you could blend in some sugar-free chocolate pudding mix (just use half the amount called for in the recipe) or swap out the vanilla extract for chocolate extract.
