Short 3-Line Description
Creamy cheesecake meets bright, refreshing lemon in this easy no-bake mousse.
Smooth, fluffy, tangy, and lightly sweetened for a delicious low-carb treat.
A simple keto-friendly, protein-rich dessert that comes together in minutes.
Can This Keto Lemon Cheesecake Mousse Support Weight Loss Goals?
This dessert can fit into a calorie-conscious eating pattern when enjoyed in an appropriate portion. Using Greek yogurt alongside cream cheese provides protein, while a low- or zero-calorie sweetener can reduce added sugar. However, ingredients such as cream cheese and heavy cream are calorie-dense, so portion size and your overall daily intake still matter.
Does Keto Lemon Cheesecake Mousse Fit a High-Protein Lifestyle?
This mousse can work well as a high-protein, low-carb dessert because it combines Greek yogurt and cream cheese for protein while using lemon for bright flavor without adding many carbohydrates. The heavy cream creates the fluffy cheesecake-like texture, while a keto-friendly sweetener replaces traditional sugar. Depending on the brands used, each serving contains relatively low net carbs and a moderate amount of protein.
My Personal Experience
- The lemon flavor is wonderfully refreshing.
Fresh lemon zest and juice cut through the richness of the cream cheese for a bright finish. - The texture is incredibly smooth.
Properly softened cream cheese blends into a silky mousse without lumps. - It tastes like cheesecake without the crust.
You get the creamy tang of cheesecake in a quick, spoonable dessert. - It is perfect for a sweet craving.
A small chilled serving feels rich and satisfying without requiring a large dessert. - The make-ahead texture is fantastic.
A few hours in the refrigerator allows the mousse to become thicker, colder, and even more cheesecake-like.
Perfect For:
This mousse is ideal for high-protein desserts, low-carb snacks, keto diet plans, after-dinner treats, summer gatherings, meal-prep desserts, and quick no-bake recipes. It is especially convenient when you want a creamy dessert without turning on the oven.

Common Mistakes to Avoid
- Using cold cream cheese: Cold cream cheese can leave lumps, so allow it to soften at room temperature first.
- Overmixing the whipped cream: Whip only until stiff peaks form; excessive whipping can make the cream grainy.
- Adding too much lemon juice: Too much liquid can make the mousse loose, so start with the recommended amount and adjust gradually.
- Skipping the chilling time: Chilling helps the mousse firm up and develop a better cheesecake-like texture.

📝 Ingredients
- 8 oz (226 g) full-fat cream cheese, softened
- ¾ cup plain Greek yogurt
- ½ cup heavy whipping cream, cold
- ⅓ cup powdered monk fruit or erythritol sweetener, or to taste
- 2 tablespoons fresh lemon juice
- 1 tablespoon finely grated lemon zest
- 1 teaspoon vanilla extract
- Pinch of salt
Optional garnish:
- Lemon zest
- Thin lemon slices
- Fresh berries, in small amounts
- A small spoonful of whipped cream
Ingredient note: Use powdered sweetener for the smoothest mousse. Granulated sweetener can leave a slightly gritty texture.
Directions
1. Soften the cream cheese
Allow the cream cheese to sit at room temperature for approximately 30 minutes.
It should be soft enough to press easily with a spatula but should not be warm or melted.
2. Prepare the cheesecake base
Add softened cream cheese, Greek yogurt, powdered sweetener, lemon juice, lemon zest, vanilla, and salt to a large mixing bowl.
Beat with an electric mixer on medium speed for 1–2 minutes, until completely smooth and creamy.
3. Taste and adjust
Taste the mixture and adjust the sweetness or lemon flavor if desired.
For a stronger citrus flavor, add another small amount of lemon zest rather than a large amount of lemon juice so the mousse does not become too loose.
4. Whip the cream
Pour the cold heavy cream into a separate chilled bowl.
Beat on medium-high speed for approximately 2–3 minutes, until stiff peaks form.
The cream should hold its shape when the beaters are lifted.
5. Fold everything together
Add about one-third of the whipped cream to the lemon cheesecake mixture and gently fold it in.
Add the remaining whipped cream in two additions, folding carefully until the mousse is light, smooth, and evenly combined.
High-protein tip: Avoid replacing all of the Greek yogurt with heavy cream if you want to maintain the recipe’s protein contribution.
6. Portion the mousse
Divide the mixture evenly among 6 small dessert glasses or jars.
Smooth the tops with a spatula or spoon.
7. Chill
Cover and refrigerate for at least 1–2 hours.
The mousse should feel cold, thick, and fluffy when ready to serve.
8. Garnish and serve
Top with a little fresh lemon zest and an optional small dollop of whipped cream.
Serve chilled.

Frequently Asked Questions
Can I make this mousse ahead of time?
Yes, preparing it several hours or even a day ahead gives the mousse time to fully chill and firm up.

Fresh lemon juice is recommended because it provides a brighter flavor, but bottled juice can be used when necessary.
How do I make the mousse thicker?
Chill it longer, and make sure the whipped cream is beaten to stiff peaks before folding it into the cheesecake mixture.
Can I use low-fat cream cheese?
Yes, although the mousse will generally be less rich and creamy than when made with full-fat cream cheese.
Is Greek yogurt necessary?
Greek yogurt adds protein and a pleasant tang, but it can be replaced with additional cream cheese if you prefer a richer cheesecake-style mousse.
Is this dessert keto-friendly?
It can fit many keto-style meal plans because it contains no traditional sugar or flour, but the exact carbohydrate content depends on the ingredients and sweetener used.
