Ingredients You’ll Need
For the Crust:

- ¼ cup sugar
- ½ cup melted butter
For the Lemon Mousse:
- 1 cup heavy whipping cream
- ½ cup powdered sugar
- 8 oz cream cheese, softened
- ½ cup fresh lemon juice (about 2-3 lemons)
- Zest of 1 lemon
- 1 teaspoon vanilla extract
- 2 teaspoons unflavored gelatin (optional, for extra firmness)
For the Lemon Glaze (Optional):
- ¼ cup fresh lemon juice
- ¼ cup sugar
- 1 tablespoon water
- 1 teaspoon cornstarch
How to Make Lemon Mousse Cake
Step 1: Prepare the Crust
- In a medium bowl, mix together the graham cracker crumbs, sugar, and melted butter until well combined.
- Press the mixture firmly into the bottom of a 9-inch springform pan or tart pan. Use the back of a spoon to create an even layer.
- Refrigerate the crust while you prepare the mousse filling.
Step 2: Make the Lemon Mousse Filling
- In a large mixing bowl, whip the heavy cream and powdered sugar until stiff peaks form. Set aside.
- In another bowl, beat the softened cream cheese until smooth. Add the lemon juice, lemon zest, and vanilla extract, mixing until fully combined.
- If using gelatin, dissolve it in 2 tablespoons of hot water and stir it into the cream cheese mixture.
- Gently fold the whipped cream into the cream cheese mixture. Be careful not to overmix to keep the mousse light and airy.
Step 3: Assemble the Cake
- Pour the lemon mousse filling over the prepared crust, spreading it evenly with a spatula.
- Refrigerate for at least 4 hours (or overnight) to allow the cake to set.
Step 4: Make the Lemon Glaze (Optional)
- In a small saucepan, combine the lemon juice, sugar, and water. Bring to a gentle simmer.
- In a separate bowl, mix the cornstarch with 1 tablespoon of water to create a slurry.
- Add the slurry to the saucepan, stirring continuously until the glaze thickens.
- Remove from heat and let it cool completely.
Step 5: Finish and Serve
- Once the mousse is set and the glaze has cooled, pour the lemon glaze over the cake, spreading it evenly.
- Refrigerate for another 30 minutes to allow the glaze to firm up.
- Carefully remove the springform pan, slice, and serve chilled. Garnish with lemon zest or fresh berries for an extra touch of elegance!
