Ingredients You’ll Need
Every ingredient in this recipe is straightforward but plays a starring role in achieving the perfect balance of flavor, texture, and color in your Lemon Blueberry Shortbread Mousse Cake Recipe. Each component works together to build layers of buttery, creamy, and fruity delight.
- 1 1/2 cups all-purpose flour: The foundation of the shortbread crust, giving it structure and a tender crumb.
- 1/2 cup powdered sugar: Adds just the right touch of sweetness to the crust while keeping it delicate.
- 1/2 cup unsalted butter, cold and cubed: Crucial for creating that rich, flaky texture in the shortbread.
- 1 cup heavy cream: Whipped to stiff peaks, it creates the light and airy mousse texture.
- 8 ounces cream cheese, softened: Brings creaminess and a subtle tang to the lemon mousse.
- Zest of 2 lemons: Infuses the mousse with fresh citrus aroma and vibrant flavor.
- 2 cups fresh blueberries: Used for the compote to add brightness, sweetness, and a gorgeous pop of color.
- 1/2 cup granulated sugar: Sweetens the mousse and balances the tart lemon perfectly.
- 1/4 cup granulated sugar for blueberry compote: Enhances the natural sweetness of the blueberries during cooking.
- 1/2 cup fresh lemon juice: The star ingredient in the mousse, offering tang and freshness.
- 1 tablespoon gelatin powder: Helps the mousse set to a velvety yet firm texture without heaviness.
- 2 tablespoons water: Needed to bloom the gelatin properly for smooth incorporation.

How to Make Lemon Blueberry Shortbread Mousse Cake Recipe
Step 1: Prepare the Shortbread Crust
Start by preheating your oven to 350°F (175°C). Using a food processor, pulse together the flour, powdered sugar, cubed butter, and a pinch of salt until the mixture looks crumbly but can hold together when pressed. This combination ensures your shortbread crust will be buttery and tender with a perfect crumb. Press this dough evenly into the bottom of a springform pan, creating a sturdy base for the mousse. Bake for 15 to 18 minutes until golden and fragrant—this baked shortbread is going to give your cake the perfect buttery crunch that contrasts beautifully with the creamy top layers. Once done, cool it completely so the mousse doesn’t melt on contact.
Step 2: Make the Lemon Mousse
While the crust cools, heat the fresh lemon juice gently in a small saucepan. Sprinkle the gelatin powder over the water to bloom it, then stir the gelatin into the warm lemon juice until dissolved. Let this cool slightly—it’s important the mixture isn’t too hot when combined with the cream cheese. Meanwhile, whip the heavy cream with granulated sugar and lemon zest until you see stiff peaks—this whipping infuses air and lightness into your cake’s texture. Blend the softened cream cheese with your cooled lemon gelatin mixture until smooth, then gently fold in the whipped cream, keeping the mixture airy and fluffy. This mousse is the heart of your cake, delivering bright lemon flavor with a melt-in-your-mouth texture.
Step 3: Assemble and Chill
Pour the luscious lemon mousse over the completely cooled shortbread crust, smoothing the top evenly. Cover and refrigerate the cake for at least 4 hours to allow the mousse to set firmly. This chilling time is essential for that perfect slice, where the mousse holds its shape yet remains soft and creamy. Patience here rewards you with an incredible texture contrast in every bite.
Step 4: Prepare the Blueberry Compote
While the mousse sets, it’s time to create the vibrant blueberry compote. In a saucepan over medium heat, combine fresh blueberries, sugar, and lemon juice. Cook gently, stirring occasionally, until the mixture thickens—about 5 to 7 minutes. This cooking process intensifies the blueberry flavor and softens the fruit into a luscious topping that brings juicy sweetness and a beautiful burst of color to your cake. Let the compote cool to room temperature before serving.
Step 5: Serve and Enjoy
Once your Lemon Blueberry Shortbread Mousse Cake Recipe has chilled and set, carefully remove the springform pan sides. Slice with a sharp knife to reveal the layers of buttery crust and creamy mousse beneath the jewel-like compote topping. Serve each slice chilled, spooning extra blueberry compote on top or on the side to elevate every bite. This cake is a showstopper with every forkful boasting a balance of textures and flavors that will delight your guests and family alike.

Garnishes
Decorating your Lemon Blueberry Shortbread Mousse Cake Recipe is half the fun! A sprinkle of fresh lemon zest or a few whole blueberries perfectly complements the flavors while adding a pop of color. If you want to get a little fancy, a light dusting of powdered sugar or a sprig of fresh mint offers a beautiful presentation and an inviting aroma that will make your guests eager to dig in.
Side Dishes
This cake shines on its own but can also be paired delightfully with fresh fruit salads or a dollop of homemade whipped cream for those who crave extra indulgence. A crisp glass of sparkling water with a twist of lemon or a refreshing herbal tea complements the dessert’s citrus notes without overpowering them, making your meal truly balanced and memorable.
Creative Ways to Present
Consider serving your cake in elegant individual portions by slicing and plating pieces with fresh blueberries scattered around. For a casual gathering, cut the cake into small bite-sized squares and arrange on a platter with mini dessert forks—perfect for sharing. You can also layer the blueberry compote in clear glasses with chunks of shortbread and whipped lemon mousse for a playful deconstructed presentation that looks as fabulous as it tastes.
Make Ahead and Storage
Storing Leftovers
After enjoying your Lemon Blueberry Shortbread Mousse Cake Recipe, store any leftovers tightly covered in the refrigerator. This cake keeps beautifully for up to 3 days, maintaining its creamy texture and fresh flavor if properly chilled. It’s best to keep the blueberry compote separate to prevent the crust from becoming soggy.
Freezing
You can freeze this mousse cake to enjoy later by wrapping it securely in plastic wrap and a layer of foil. Freeze for up to one month. When ready to eat, thaw it overnight in the refrigerator. Note that the texture might be slightly altered, but it will still be delicious and refreshing.
Reheating
Since this cake is best served chilled, reheating is not recommended. Instead, allow any frozen slices to thaw naturally in the fridge and serve cold for the best texture and flavor experience.
FAQs
Can I use frozen blueberries instead of fresh?
Yes, you can use frozen blueberries for the compote if fresh aren’t available. Just thaw and drain them slightly before cooking to avoid excess moisture that could dilute the flavor.
Is gelatin necessary for the mousse?
Gelatin is important for setting the mousse so it holds its shape when sliced. Without it, the mousse would be too soft and not firm enough to create those beautiful, clean layers.
Can I make this recipe dairy-free?
For a dairy-free version, substitute the cream cheese and heavy cream with non-dairy alternatives like coconut cream and a plant-based cream cheese, though the texture and flavor will vary slightly.
What type of pan should I use?
A springform pan is best for this recipe because it allows you to remove the cake easily without damaging the delicate mousse layers. An 8-inch pan works perfectly.
How long does the cake need to chill?
A minimum of 4 hours in the refrigerator is required for the mousse to set properly, but chilling overnight will result in even better texture and flavor melding.

Instructions
- Prepare Shortbread Crust: Preheat the oven to 350°F (175°C). In a food processor, pulse together the flour, powdered sugar, cold cubed butter, and a pinch of salt until the mixture is crumbly. Press this mixture evenly into the base of a springform pan. Bake for 15-18 minutes, or until golden brown. Remove from oven and let cool completely.
- Make Lemon Mousse: In a small bowl, bloom the gelatin powder by mixing it with 2 tablespoons of water, then gently heat 1/2 cup fresh lemon juice in a saucepan without boiling. Stir in the bloomed gelatin until fully dissolved, then allow the mixture to cool to room temperature. Meanwhile, whip the heavy cream with granulated sugar and lemon zest until stiff peaks form. In another bowl, beat the softened cream cheese until smooth, then mix in the cooled lemon and gelatin mixture. Gently fold the whipped cream into the cream cheese mixture until well combined.
- Assemble and Chill: Pour the lemon mousse evenly over the cooled shortbread crust. Smooth the top and refrigerate the cake for at least 4 hours, or until the mousse is fully set.
- Prepare Blueberry Compote: In a saucepan over medium heat, combine fresh blueberries, 1/4 cup granulated sugar, and 1 tablespoon fresh lemon juice. Cook for 5-7 minutes, stirring occasionally, until the mixture thickens to a compote-like consistency. Remove from heat and allow to cool to room temperature.
- Serve: Carefully remove the sides of the springform pan. Slice the mousse cake and serve chilled with a generous spoonful of blueberry compote on top or on the side.
Notes
- For best results, ensure the shortbread crust is completely cool before adding the mousse to prevent melting.
- If you prefer a firmer mousse, increase gelatin to 1.5 tablespoons.
- Use fresh lemon juice and zest for the brightest flavor.
- Blueberry compote can be made in advance and stored refrigerated up to 3 days.
- For a smoother compote, you can lightly mash the blueberries during cooking.
