Step‑by‑Step Instructions for Lemon Blueberry Shortbread Mousse Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This temperature is crucial for achieving a perfectly baked shortbread crust. While the oven heats up, gather your ingredients and prep a 9-inch springform pan by greasing it lightly with butter or cooking spray.
Step 2: Make the Shortbread Crust
In a mixing bowl, combine all-purpose flour, powdered sugar, unsalted butter, and a pinch of salt. Use a pastry cutter or your fingers to blend the mixture until it resembles coarse crumbs. Press this mixture firmly into the bottom of your prepared springform pan, ensuring it’s even. Bake for 15 to 18 minutes until the crust is golden brown, then allow it to cool completely.
Step 3: Prepare the Gelatin
For the lemon mousse, start by sprinkling gelatin powder over a small bowl of water. Let it sit for about 5 minutes to bloom. Meanwhile, in a saucepan, heat fresh lemon juice until steaming, then stir in the bloomed gelatin until fully dissolved. Remove from heat and let this mixture cool to room temperature while you continue with the next steps.
Step 4: Whip the Cream
In a clean mixing bowl, combine heavy cream, granulated sugar, and lemon zest. Using an electric mixer, whip this mixture until stiff peaks form, which should take about 3 to 5 minutes. The cream will become light and fluffy, providing an airy texture to your Lemon Blueberry Shortbread Mousse Cake. Set the whipped cream aside gently.
Step 5: Combine Mousse Ingredients
In another bowl, whip cream cheese until smooth and creamy. Once the gelatin mixture has cooled, carefully add it to the cream cheese while mixing until fully combined. Finally, fold in your whipped cream from the previous step gently, ensuring you maintain the airy texture that makes the mousse light and delectable.
Step 6: Make the Blueberry Compote
In a medium saucepan, combine fresh blueberries, granulated sugar, and a splash of lemon juice. Cook over medium heat until the blueberries begin to soften and burst, about 5-7 minutes. Ensure to stir occasionally and keep an eye on the berries. Once thickened, remove from heat and let it cool to room temperature before layering.
Step 7: Assemble the Cake
Take your cooled shortbread crust as a base. Begin by spreading half of the lemon mousse over it, smoothing it out evenly. Follow this with half of the blueberry compote. Repeat by layering the remaining mousse and finally topping it with the rest of the blueberry compote, creating gorgeous layers throughout the cake.
Step 8: Chill the Cake
Cover your assembled Lemon Blueberry Shortbread Mousse Cake with plastic wrap or a lid. Place it in the refrigerator and let it chill for at least 4 hours, preferably overnight, until set. This chilling allows the flavors to meld beautifully and the mousse to firm up to the perfect consistency.
Step 9: Serve the Cake
Once set, carefully run a knife around the edge of the springform pan to loosen the mousse cake. Remove the sides of the pan and transfer the cake to a serving platter. Slice into wedges, serve chilled, and enjoy the delightful flavors of your Lemon Blueberry Shortbread Mousse Cake with friends and family!

Lemon Blueberry Shortbread Recipe FAQs
How do I choose ripe blueberries for the compote?
Absolutely! Select blueberries that are firm, plump, and have a deep blue color. Avoid any that have green or red spots – these are signs of under-ripeness. A great visual cue is bright, shiny skin without dark spots; if they look dull, they’re likely past their prime.
How should I store my Lemon Blueberry Shortbread Mousse Cake?
Very simple! Store any leftover cake in an airtight container in the refrigerator for up to 3 days. This helps maintain its freshness and delightful flavors. I often use a cake dome, as it allows for great airflow while still protecting the cake from drying out.
Can I freeze Lemon Blueberry Shortbread Mousse Cake?
Absolutely! For best results, wrap individual slices tightly in plastic wrap and then place them in a freezer bag. This method can keep your delicious cake frozen for up to 3 months. When you’re ready to enjoy, simply move the slices to the fridge to thaw overnight.
What if my mousse doesn’t set properly?
Don’t worry! If your mousse is too runny after chilling, it may be due to insufficiently bloomed or dissolved gelatin. Next time, ensure you let the gelatin sit for at least 5 minutes in the water before heating it with the lemon juice. If it still doesn’t set, consider adding more gelatin; use a small amount dissolved in water to thicken it up during preparation.
Are there any dietary restrictions I should consider when making this recipe?
Very mindful! For those with gluten sensitivities, substituting all-purpose flour with a gluten-free flour blend works wonderfully without compromising texture. Additionally, you can create a vegan version by using coconut cream and agar-agar in place of heavy cream and gelatin respectively. Always check for allergies with your guests, especially with ingredients like dairy and nuts.
