1. Prepare the Cream Cheese Mixture:

Start by beating the softened cream cheese in a large mixing bowl. You want the cream cheese to be soft and smooth, so if it’s too stiff, leave it out for a few minutes to come to room temperature. Use a hand mixer or a whisk to beat the cream cheese until it becomes creamy and smooth. This step is key to ensuring your mousse will have the right texture.

Once it’s nice and smooth, add the sweetened condensed milk, fresh lemon juice, lemon zest, and vanilla extract. Mix everything together until fully combined. The sweetened condensed milk will add just the right amount of sweetness, and the lemon zest will provide a burst of citrus flavor that makes this dessert so refreshing.

2. Whip the Cream:

In a separate bowl, take the cold heavy whipping cream and whip it with powdered sugar until stiff peaks form. This means that when you lift the whisk out of the cream, it should hold its shape. To do this effectively, make sure your whipping cream is chilled. Using a hand mixer on high speed for about 3–5 minutes should do the trick. The powdered sugar helps stabilize the whipped cream and gives it a light sweetness.

3. Fold the Mixtures Together:

Now, it’s time to gently fold the whipped cream into the lemon cream cheese mixture. The key here is to fold, not stir, to keep the whipped cream airy and light. Use a spatula and gently mix the two together, taking care not to deflate the whipped cream. Keep folding until everything is fully incorporated, and the mixture looks fluffy and smooth.

4. Assemble the Mousse:

Once your mousse mixture is ready, it’s time to get it into individual servings. You can spoon the mousse directly into small dessert cups or bowls, or pipe it for a more elegant look. If you want to add a cheesecake-inspired touch, you can layer some crushed graham crackers at the bottom of each cup before adding the mousse mixture. This gives it the feel of a cheesecake without the need for baking.

Smooth the tops of the mousse and prepare for the next step.

5. Chill and Serve:

Refrigerate the mousse for at least 2 hours. The chilling time allows the mousse to set and reach the perfect consistency. If you’re in a hurry, you can place the mousse in the freezer for 30 minutes for a quicker chill, but I recommend letting it set in the fridge for the best texture.

Once chilled, your Lemon Cheesecake Mousse is ready to serve. Garnish it with fresh lemon slices, extra lemon zest, berries, or mint leaves for a beautiful presentation.
