- 1 1/2 cups heavy cream
- For the Blueberry Layer:
- 1 cup blueberries (fresh or frozen)
- 1/4 cup sugar
- 1 tablespoon water
Step-by-Step Instructions
- Prepare the Shortbread Base:
- Preheat your oven to 350°F (175°C).
- In a mixing bowl, combine flour and sugar. Add chilled butter and blend using a pastry cutter or a food processor until the mixture resembles coarse crumbs.
- Press the mixture into the bottom of a greased 9-inch springform pan and bake for 18-20 minutes or until lightly golden. Allow to cool completely.
- Make the Lemon Mousse:
- Sprinkle gelatin over cold water in a small bowl and let it bloom for about 5 minutes.
- In a saucepan, combine granulated sugar, lemon juice, and lemon zest, and heat until sugar dissolves completely. Remove from heat, add the bloomed gelatin, and stir until gelatin dissolves.
- Allow the mixture to cool to room temperature. Meanwhile, whip the heavy cream to stiff peaks. Gently fold the lemon mixture into the whipped cream until well combined.
- Pour the mousse over the cooled shortbread base. Chill in the refrigerator for at least 1 hour to set.
- Prepare the Blueberry Topping:
- In a saucepan over medium heat, combine blueberries, sugar, and water. Cook until the blueberries burst and the sauce thickens slightly, about 10 minutes. Allow to cool.
- Once cooled, spread the blueberry topping over the set lemon mousse layer.
- Chill and Serve:
- Refrigerate the cake for at least 3 more hours or overnight to ensure all layers are set.
- When ready to serve, carefully remove the cake from the springform pan and place it on a serving plate.

Serving and Storage Tips for Lemon Blueberry Shortbread Mousse Cake
When it comes to serving and storing your Lemon Blueberry Shortbread Mousse Cake, a few expert tips can help maintain the cake’s freshness and enhance its flavor profile. Here’s how to ensure that every slice is as delicious as it was when first prepared.
Serving Tips:
- Temperature: Serve this cake chilled. Remove it from the refrigerator just before serving to keep the mousse firm and the base crunchy.
- Cutting: Use a sharp, thin-bladed knife to cut the cake. For clean slices, dip the knife in hot water and wipe it dry between each cut. This method melts through the mousse smoothly, ensuring beautifully presented slices.
- Presentation: Enhance the visual appeal of the cake by garnishing it right before serving. A few fresh blueberries, a sprinkle of lemon zest, or even a few mint leaves can add a refreshing contrast and make the cake pop on the plate.
- Portion Size: This cake is quite rich, so consider serving smaller portions. A little goes a long way in satisfying those dessert cravings.
Storage Tips:
- Refrigeration: Always store the Lemon Blueberry Shortbread Mousse Cake in the refrigerator. Because it contains a mousse made with heavy cream and gelatin, keeping it chilled will preserve its texture and flavor.
- Covering: Cover the cake with a cake dome or loosely with plastic wrap. This prevents the cake from absorbing any odors from the refrigerator and also keeps the mousse from drying out.
- Duration: The cake will keep well in the refrigerator for up to 3 days. Beyond that, the texture and freshness of the ingredients, especially the mousse and berries, may begin to deteriorate.
- Freezing: Freezing this cake is possible but not recommended as the texture of the mousse can change, becoming grainy or separated once thawed. If you must freeze it, wrap the cake tightly in plastic wrap and then in aluminum foil. Thaw overnight in the refrigerator before serving.
By following these serving and storage tips, your Lemon Blueberry Shortbread Mousse Cake will maintain its optimal flavor and texture, making every slice as enjoyable as the last. Whether serving at a special event or as a delightful finish to a family meal, this cake is sure to impress.
1. Can I make the Lemon Blueberry Shortbread Mousse Cake ahead of time?
Yes, you can prepare this cake ahead of time. It’s actually recommended to make it at least a day in advance to ensure that all the layers set properly and the flavors meld together nicely. The completed cake can be stored in the refrigerator for up to 3 days before serving. Just remember to keep it covered to protect its flavor and texture.
2. What can I use if I don’t have fresh blueberries?
If fresh blueberries are not available, frozen blueberries make a great substitute. There’s no need to thaw them before use; you can cook them directly from frozen to make the blueberry layer. Just be aware that frozen blueberries might release more juice than fresh, so you might need to cook them slightly longer to reduce the sauce to the desired consistency.
3. Is there a vegetarian alternative to gelatin for the mousse?
Yes, for a vegetarian version of the mousse, you can use agar-agar instead of gelatin. Agar-agar is a plant-based gelatin substitute derived from seaweed and works well in setting mousses. Use agar-agar in the same proportion as gelatin in the recipe, but make sure to bring it to a boil for about 1-2 minutes to activate its setting properties before cooling and adding it to the mixture.
4. How can I prevent the mousse from being too runny?
To ensure your mousse sets properly and isn’t too runny, make sure to:
- Measure ingredients accurately: Especially the water and gelatin.
- Allow the gelatin to bloom fully: This means letting it sit in cold water until it becomes spongy before dissolving it in the warm lemon mixture.
- Chill the lemon mixture to room temperature before folding into the whipped cream: Adding it while hot can melt the whipped cream, causing the mixture to lose volume and firmness.
- Whip the cream to stiff peaks: This means the cream should be whipped until it holds its shape firmly. Under-whipped cream will not give the structure needed for the mousse to set.
- Chill the mousse adequately: Allow sufficient time for the mousse to set in the refrigerator, ideally overnight.
