Easy 4-Ingredient Lemon Cheesecake Mousse
-
Prep time: 10 minutes
-
Chilling time: 30 minutes (optional, but recommended)
-
Servings: 4
Ingredients
-
8 oz (225g) Cream Cheese: Softened to room temperature (this is crucial for a smooth texture).
-
1 cup (240ml) Heavy Whipping Cream: Cold, straight from the fridge.
-
1/2 cup (60g) Powdered Sugar: Adjust based on your preference for sweetness.
-
1/4 cup Fresh Lemon Juice: About 1–2 large lemons.
-
Optional: 1 tsp Lemon Zest (for extra zing) and a splash of vanilla extract.
Instructions
-
Cream the Base: In a large mixing bowl, beat the softened cream cheese and powdered sugar together using a hand mixer or stand mixer until the mixture is smooth and creamy. There should be no lumps.
-
Add the Citrus: Slowly pour in the lemon juice (and zest, if using). Mix on low speed until combined.
-
Whip the Cream: In a separate chilled bowl, whip the heavy cream until stiff peaks form.
-
Pro Tip: If you want to save a step, you can slowly pour the liquid heavy cream directly into the cream cheese mixture and whip them together until thick, but whipping them separately usually results in a fluffier mousse.
-
-
Fold Together: Gently fold the whipped cream into the lemon-cheese mixture using a spatula. Use a “cut and fold” motion rather than stirring to keep the air in the mousse.
-
Chill and Serve: Spoon or pipe the mousse into small glasses or ramekins. Let them sit in the fridge for at least 30 minutes to set.
-
Garnish: Top with extra lemon zest, a mint leaf, or crushed graham crackers for a “cheesecake crust” feel.
A Quick Tip for Success
If your mousse looks a bit too soft, don’t worry—the fat in the cream cheese and the cold temperature of the fridge will help it firm up significantly as it rests.
