Ingredients

For the Shortbread Crust:

• 1 1/2 cups all-purpose flour
• 1/2 cup powdered sugar
• 1/2 cup unsalted butter, cold and cubed
• Pinch of salt

For the Lemon Mousse:

• 1 cup heavy cream
• 1/2 cup granulated sugar
• Zest of 2 lemons
• 1/2 cup fresh lemon juice
• 1 tablespoon gelatin powder
• 2 tablespoons water
• 8 ounces cream cheese, softened

For the Blueberry Compote:

• 2 cups fresh blueberries
• 1/4 cup granulated sugar
• 1 tablespoon fresh lemon juice

Instructions

Step 1: Prepare the Shortbread Crust

1. Preheat the oven to 350°F (175°C). Grease and line a 9-inch springform pan with parchment paper.
2. In a food processor, combine the flour, powdered sugar, cold butter cubes, and a pinch of salt. Pulse until the mixture resembles coarse crumbs.
3. Press the mixture evenly into the bottom of the prepared pan.
4. Bake for 15-18 minutes, or until lightly golden. Remove from the oven and let it cool completely.

Step 2: Make the Lemon Mousse

1. In a small bowl, sprinkle the gelatin powder over 2 tablespoons of water and let it bloom for 5 minutes.
2. In a saucepan, gently heat the lemon juice until warm, then stir in the bloomed gelatin until fully dissolved. Let this cool to room temperature.
3. In a large bowl, whip the heavy cream, sugar, and lemon zest until stiff peaks form.
4. In another bowl, beat the softened cream cheese until smooth. Gradually add the lemon juice mixture, beating until fully combined.
5. Gently fold in the whipped cream until well incorporated.

Step 3: Prepare the Blueberry Compote

1. In a saucepan, combine the blueberries, sugar, and lemon juice.
2. Cook over medium heat for about 5-7 minutes, stirring occasionally, until the blueberries soften and release their juices. Allow the compote to cool to room temperature.

Step 4: Assemble the Mousse Cake

1. With the shortbread crust cooled, spread half of the lemon mousse over the crust.
2. Spoon half of the blueberry compote over the mousse, then spread the remaining lemon mousse on top.
3. Finish with the remaining blueberry compote, spreading it evenly over the top.
4. Refrigerate the mousse cake for at least 4 hours, or until fully set.

Step 5: Serve

1. Before serving, run a knife around the edge of the pan to loosen the cake. Carefully remove the sides of the springform pan.
2. Slice and serve chilled, garnished with fresh blueberries and a sprig of mint if desired.
