Lemon Cheesecake Mousse Ingredients

For the Mousse

8 oz cream cheese – Provides the creamy base and structure. Substitution: Neufchâtel cheese for lower fat content.
½ cup granulated sugar – Sweetens the mousse. Substitution: Use honey or a sugar alternative for a healthier option.
1 cup heavy whipping cream – Adds airiness and richness. Substitution: Use coconut cream for a dairy-free alternative.
1 teaspoon vanilla extract – Enhances the flavor profile. No substitution needed, but pure vanilla is preferable.
Zest of 1 lemon – Introduces fresh, aromatic citrus notes. Substitution: Lime zest for an alternative citrus profile.
½ cup fresh lemon juice – Provides acidity and tartness. Substitution: Substitute with lime juice for a different flavor.
2 teaspoons gelatin powder – Acts as a stabilizer to help the mousse set. Substitution: Agar-agar for a vegetarian alternative.
3 tablespoons water (for gelatin) – Used to bloom the gelatin.
Pinch of salt – Balances the sweetness. No substitution needed.

Step‑by‑Step Instructions for Lemon Cheesecake Mousse

Step 1: Bloom the Gelatin
In a small bowl, combine 2 teaspoons of gelatin powder with 3 tablespoons of water. Allow the mixture to sit for about 5–10 minutes until the gelatin blooms and becomes thickened. This step is crucial for ensuring a stable Lemon Cheesecake Mousse later, so make sure the gelatin is fully absorbed before proceeding.

Step 2: Mix Cream Cheese and Sugar
In a large mixing bowl, use a hand mixer to beat 8 oz of cream cheese and ½ cup granulated sugar together until the mixture is smooth and creamy, about 2–3 minutes. The cream cheese should be free of lumps for an elegant, light texture in your mousse. Aim for a light and airy consistency as you blend.

Step 3: Add Flavors
Next, incorporate the zest of 1 lemon and ½ cup of fresh lemon juice to the cream cheese mixture. Mix well until all the ingredients are thoroughly combined. You should see the mixture taking on a beautiful light yellow hue, infused with the refreshing citrus notes that make this Lemon Cheesecake Mousse so delightful and zesty.

Step 4: Dissolve the Gelatin
Gently heat the bloomed gelatin in the microwave or over low heat until it is completely dissolved, about 30 seconds. Be careful not to boil it! Allow the gelatin to cool slightly before adding it to the cream cheese mixture, ensuring it blends seamlessly and doesn’t clump together in your mousse.

Step 5: Whip the Cream
In a separate bowl, whip 1 cup of heavy whipping cream with 1 teaspoon of vanilla extract until stiff peaks form. This process usually takes about 3–5 minutes. The whipped cream should be thick enough to hold its shape, providing the lightness needed for the Lemon Cheesecake Mousse.

Step 6: Combine Mixtures
Gently fold the whipped cream into the cream cheese mixture. Start with one-third of the whipped cream to lighten the mixture and then gradually add the rest, using a spatula to create a smooth and airy texture. Be careful not to overmix, as you want to retain the mousse’s airy consistency that will make it irresistible.

Step 7: Chill the Mousse
Spoon the combined Lemon Cheesecake Mousse into individual serving cups or a large serving bowl. Cover with plastic wrap and refrigerate for at least 4 hours, allowing the mousse to set properly. This chilling time will ensure that each serving is perfectly light and creamy when it’s time to serve.

Step 8: Garnish and Serve
Once set, it’s time to add your finishing touches! Top the mousse with additional lemon zest, a dollop of whipped cream, or fresh berries for a pop of color. Serve the Lemon Cheesecake Mousse chilled, and watch as your guests delight in its fresh, creamy elegance.

Expert Tips for Lemon Cheesecake Mousse

Dissolve Gelatin Well: Ensure the gelatin is completely dissolved to avoid a runny mousse. Heating it too much can ruin the texture.
Fold, Don’t Stir: Gently fold the whipped cream into the cream cheese mixture to maintain the mousse’s light and airy consistency; overmixing can lead to heaviness.
Chill Appropriately: For best results, allow the mousse to set in the refrigerator for at least 4 hours. This allows the flavors to meld beautifully and for the mousse to achieve its perfect texture.
Garnish Creatively: Enhance the presentation of your Lemon Cheesecake Mousse by adding fresh berries or a sprig of mint. It’ll impress your guests visually and adds extra layers of flavor.
Make Ahead: This mousse can be prepared up to 2 days in advance, making it an excellent choice for effortless entertaining. Just remember to cover it well to keep its freshness!

Make Ahead Options

Preparing your Lemon Cheesecake Mousse in advance is a game-changer for busy home cooks! You can make the mousse up to 2 days ahead of time, giving you a delicious dessert ready for any occasion. Simply follow the recipe through to Step 6, then cover the mousse in individual cups with plastic wrap and refrigerate. This helps maintain its fluffy texture and prevents any browning. When you’re ready to impress your guests, simply garnish with lemon zest, whipped cream, or fresh berries before serving. Enjoy the time-saving benefits while still delivering a scrumptious, restaurant-quality dessert!
