Recipe Ingredients
Below are the simple ingredients you will need to make this keto cream cheese dessert. Scroll to the recipe card at the bottom of the page to see the exact amounts for each ingredient.
- Heavy Cream: Helps stabilize the mousse to hold its shape and maintain an airy texture. It also adds a luscious richness and satisfying finish.
- Cream Cheese: Use full-fat cream cheese for the best results. It gives the dessert a creamy taste.
- Monk Fruit Sweetener: Powdered monk fruit sugar is essential to a smooth, even texture in this keto mousse recipe. I don’t recommend using granulated or the texture will be very gritty.

Tips and Tricks
- Allow the lemon mousse enough time to chill in the fridge before serving. This will give it the best taste and texture – it’s worth the wait!
- Pipe the mousse into containers instead of spooning it in for the best presentation. Transfer the cheesecake fluff to a large ziplock bag, cut off the tip of one corner, then pipe the mixture into serving containers.
- If you don’t want to use monk fruit sweetener, you can swap it for regular powdered sugar to make traditional lemon cheesecake mousse.
