Step‑by‑Step Instructions for Lemon Blueberry Shortbread Mousse Cake
Step 1: Prepare the Shortbread Crust
Preheat your oven to 350°F (175°C) and grease a 9-inch springform pan. In a food processor, combine all-purpose flour, powdered sugar, unsalted butter, and a pinch of salt, mixing until the mixture resembles coarse crumbs. Press this mixture firmly into the bottom of the prepared pan and bake for 15-18 minutes until lightly golden. Allow the crust to cool completely before adding the mousse.
Step 2: Make the Lemon Mousse
In a small bowl, bloom gelatin by mixing it with water and letting it sit for about 5 minutes. Meanwhile, gently warm lemon juice in a saucepan over low heat just until warm, then stir in the bloomed gelatin until fully dissolved. Allow this mixture to cool slightly. In a separate bowl, whip heavy cream with granulated sugar and lemon zest until stiff peaks form. Then, mix together the cream cheese and the cooled lemon mixture before folding in the whipped cream gently to keep it light and airy.
Step 3: Prepare the Blueberry Compote
In a medium saucepan over medium heat, combine fresh blueberries, granulated sugar, and fresh lemon juice. Stir occasionally, cooking for about 5-7 minutes, until the blueberries begin to soften and release their juices, creating a vibrant compote. Once it has thickened slightly, remove from heat and let it cool down to room temperature, as this will prevent it from melting the mousse layers.
Step 4: Assemble the Mousse Cake
Once your shortbread crust has cooled, layer half of the lemon mousse evenly over the crust, smoothing the top with a spatula. Next, spoon half of the blueberry compote over the mousse, creating a beautiful contrast of colors. Repeat the layers with the remaining lemon mousse and blueberry compote, finishing with compote on top. Cover the cake with plastic wrap and refrigerate for at least 4 hours to firmly set.
Step 5: Serve
After chilling, carefully loosen the edges of the Lemon Blueberry Shortbread Mousse Cake with a knife and gently remove the sides of the springform pan. Slice the cake into wedges and serve chilled, garnishing with fresh berries or a dollop of whipped cream, if desired. This dessert not only looks stunning but also offers a delightful burst of flavor that is sure to impress!
Make Ahead Options
These Lemon Blueberry Shortbread Mousse Cakes are perfect for meal prep enthusiasts! You can prepare the shortbread crust up to 24 hours in advance, simply store it covered at room temperature to maintain its crispness. Additionally, the blueberry compote can be made and refrigerated for up to 3 days ahead, ensuring that it’s ready when you’re assembling the cake. To further streamline your process, whip the lemon mousse and refrigerate it for up to 24 hours before layering. When you’re ready to serve, simply assemble the mousse with the cooled layers and allow it to chill for at least 4 hours. This way, you’ll enjoy delicious, freshly prepared dessert with minimal effort on busy evenings!

Lemon Blueberry Shortbread Mousse Cake Recipe FAQs
How do I choose the best blueberries for the compote?
Absolutely! When selecting fresh blueberries, look for ones that are plump, firm, and have a deep blue color. Avoid any with dark spots or a dull appearance, as these may indicate overripeness. If you’re using frozen blueberries instead, ensure they are unsweetened; simply thaw and drain excess liquid before use for the best flavor.
How should I store the mousse cake?
To keep the Lemon Blueberry Shortbread Mousse Cake fresh, store it in an airtight container in the refrigerator. It’s best enjoyed within 3 days, which allows the flavors to meld beautifully while maintaining the cake’s delightful texture. If you notice any condensation upon opening the container, gently blot it with a paper towel to preserve that fluffy mousse!
Can I freeze the mousse cake, and if so, how?
Sure thing! To freeze your mousse cake, wrap it tightly in plastic wrap followed by aluminum foil to prevent freezer burn. It can be stored this way for up to 1 month. When you’re ready to indulge again, simply transfer it to the fridge overnight to thaw. Avoid using a microwave, as the texture is best preserved by slow thawing in the fridge.
What if my mousse doesn’t set properly?
Very! If your mousse isn’t setting, it may be due to the gelatin not dissolving completely. Ensure that while blooming the gelatin, you give it enough time and stir well to dissolve in warm liquid. If it still seems too soft, a little troubleshooting is in order: you might need to chill it a bit longer before assembling. If making a vegan version with agar-agar, be sure to follow the boiling instructions, as agar demands a higher temperature to activate.
Is this dessert friendly for people with allergies?
It can be! The Lemon Blueberry Shortbread Mousse Cake can easily be made gluten-free by substituting all-purpose flour with a gluten-free blend. Additionally, for those who are vegan or lactose intolerant, use plant-based butter in the crust, coconut cream in the mousse, and agar-agar in place of gelatin. Always double-check ingredient labels to avoid cross-contamination, especially if allergies are severe.
How long can I keep the mousse cake in the fridge?
You can keep the Lemon Blueberry Shortbread Mousse Cake stored in the refrigerator for up to 3 days. Just ensure it remains in an airtight container to maintain freshness. After this timeframe, the texture may begin to change, but it should still be delicious.
