Step-by-Step Instructions

Follow these steps to create a delicious Lemon Blueberry Shortbread Mousse Cake:

Prepare the Shortbread Crust

• Preheat your oven to 350°F (175°C). In a mixing bowl, cream together the softened butter and sugar until light and fluffy. Gradually add the flour and salt, mixing until a dough forms.

Bake the Crust

• Press the dough into the bottom of a 9-inch springform pan evenly. Bake for 20-25 minutes or until lightly golden. Remove from the oven and let it cool completely.

Make the Lemon Mousse

• In a small bowl, sprinkle gelatin over cold water and let it sit for 5 minutes to bloom. In a saucepan, combine lemon juice, lemon zest, and sugar over medium heat. Stir until the sugar dissolves. Remove from heat and add the bloomed gelatin, stirring until dissolved.

Whip the Cream

• In a separate mixing bowl, whip the heavy cream until soft peaks form. Gradually fold the lemon mixture into the whipped cream until fully combined.

Assemble the Cake

• Pour the lemon mousse over the cooled shortbread crust and smooth the top. Refrigerate for at least 2 hours or until the mousse is set.

Prepare the Blueberry Compote

• In a saucepan over medium heat, combine the blueberries, sugar, lemon juice, cornstarch, and water. Cook for 5-7 minutes, stirring gently until the blueberries release their juices and the mixture thickens. Remove from heat and let it cool.

Top the Cake

• Once the mousse is set, pour the cooled blueberry compote over the top of the cake, spreading it evenly. Refrigerate for an additional hour before serving.

Serve the Cake

• Carefully remove the sides of the springform pan. Slice and serve chilled, garnished with extra blueberries or lemon zest if desired.

Additional Tips

To make the most of your Lemon Blueberry Shortbread Mousse Cake, consider these tips:

1. Chill the Ingredients: For a lighter texture, chill your mixing bowls and beaters before whipping the cream, as cold equipment helps create a better mousse.
2. Use Fresh Ingredients: Opt for fresh lemons and blueberries for the best flavor. The zest and juice from fresh lemons enhance the cake’s brightness.
3. Don’t Overmix the Mousse: When folding the whipped cream into the lemon mixture, be gentle to maintain the airy texture of the mousse.
4. Add a Layer of Blueberry Sauce: For added flavor, drizzle homemade blueberry sauce between the layers of mousse and shortbread.
5. Test the Shortbread: Make sure the shortbread crust is baked until lightly golden, as this will provide the best texture and flavor.
6. Adjust Sweetness: Taste the mousse before setting it; feel free to adjust the sugar according to your preference or the tartness of the lemons.
7. Let It Set: Allow the mousse cake to chill in the refrigerator for several hours (or overnight) for the best results; this helps the layers to set nicely.
8. Garnish Creatively: Top with additional blueberries, lemon slices, or a sprinkle of powdered sugar right before serving for an appealing presentation.
9. Slice with Warm Water: Dip your knife in warm water before slicing to create clean edges on the mousse cake.
10. Store Properly: Keep any leftovers in the refrigerator, covered with plastic wrap, for up to 3 days for the best freshness.
