Step-by-Step Instructions

Here’s how to make Lemon Blueberry Shortbread Mousse Cake:

Prepare the Shortbread Base:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line the bottom of a 9-inch springform pan with parchment paper.
2. Make the Dough: In a medium bowl, cream together the softened butter and sugar until light and fluffy. Gradually mix in the flour and salt until a dough forms.
3. Press into Pan: Press the dough evenly into the bottom of the prepared pan. Use a flat-bottomed glass or your hands to smooth it out.
4. Bake: Bake for 12-15 minutes, or until the edges are golden brown. Let it cool completely in the pan.

Lemon Mousse:

5. Whip the Cream: In a large bowl, whip the heavy cream to stiff peaks. Set aside.
6. Cream the Cheese: In another bowl, beat the softened cream cheese with powdered sugar, lemon juice, lemon zest, and vanilla extract until smooth and creamy.
7. Optional Gelatin Step: If using gelatin, dissolve it in 2 tablespoons of hot water. Let it cool slightly, then mix it into the cream cheese mixture.
8. Fold in the Whipped Cream: Gently fold the whipped cream into the lemon mixture until well combined and fluffy.

Blueberry Compote:

9. Cook the Blueberries: In a small saucepan, combine the blueberries, sugar, and lemon juice. Cook over medium heat for 5-7 minutes, stirring occasionally.
10. Thicken the Sauce: Stir in the cornstarch slurry and cook for another 2-3 minutes until the compote thickens. Remove from heat and let it cool completely.

Assemble the Cake:

11. Layer the Mousse: Spread the lemon mousse evenly over the cooled shortbread base, smoothing the top with a spatula.
12. Add the Blueberry Compote: Gently spread the cooled blueberry compote over the mousse layer.
13. Chill: Cover the cake and refrigerate for at least 3 hours, or until set.

Decorate and Serve:

14. Garnish: Before serving, garnish the cake with fresh blueberries, lemon slices, or mint leaves for a stunning presentation.
15. Slice and Serve: Carefully remove the sides of the springform pan, slice the cake, and serve chilled.
