How to Make Lemon Blueberry Shortbread Mousse Cake Recipe
Step 1: Prepare the Shortbread Crust
Start off this Lemon Blueberry Shortbread Mousse Cake Recipe by combining your dry ingredients—flour, powdered sugar, and a pinch of salt—with cold cubed butter in a food processor. Pulse until you get coarse crumbs that hold together when pressed. Press this mixture evenly into the bottom of your pan, then bake until it’s just turning a lovely golden shade. Cooling the crust completely is key to avoid melting the mousse later on.
Step 2: Make the Lemon Mousse
Gently warming the fresh lemon juice to dissolve the bloomed gelatin is the next crucial step. This ensures the mousse will set perfectly while staying light as air. Whip your heavy cream with sugar and lemon zest until stiff peaks form for that delightful, creamy texture. Then beat softened cream cheese smooth before gradually folding in the cooled lemon-gelatin mixture and the whipped cream. This blend is where that fresh lemon flavor really shines.
Step 3: Prepare the Blueberry Compote
Cook your fresh blueberries over medium heat with a touch of sugar and lemon juice until they soften and release their juices. This compote will bring a glossy, fruity layer that balances the tart lemon mousse with its natural berry sweetness. Make sure to let it cool to room temperature before assembling to maintain the perfect texture contrast in the cake.
Step 4: Assemble the Cake
Begin by spreading half of the blueberry compote directly over your cooled shortbread crust, creating a juicy base layer. Then, gently spoon and spread the luscious lemon mousse over the compote, smoothing it evenly. Finish the cake by topping it with the remaining blueberry compote, which adds a gorgeous jewel-like surface. Refrigerate your creation for at least four hours until beautifully set and ready to wow your guests.
Step 5: Serve and Enjoy
Once chilled, slice this dreamy Lemon Blueberry Shortbread Mousse Cake Recipe with a sharp knife for clean cuts. It’s best served cold, with the butteriness of the shortbread, zesty mousse, and sweet blueberries working harmoniously to delight the senses.

Garnishes
Elevate your cake’s presentation by adding a few fresh blueberries and a sprig of mint on top right before serving. The mint adds a refreshing aroma while the berries reinforce that vibrant color and fruity punch. A light dusting of powdered sugar over the top can also mimic delicate morning frost for an elegant finish.
Side Dishes
This cake pairs beautifully with a simple scoop of vanilla bean ice cream or a dollop of lightly sweetened whipped cream. For an adult twist, serve it alongside a glass of chilled sparkling wine or a fragrant cup of Earl Grey tea to complement the citrus and berry notes.
Creative Ways to Present
Try serving your Lemon Blueberry Shortbread Mousse Cake Recipe in individual clear glasses or jars for a modern touch. Layer the crust, mousse, and compote separately to showcase the stunning colors and textures. You can also add thin lemon slices between layers to add extra brightness both visually and flavor-wise.
Make Ahead and Storage
Storing Leftovers
Keep any leftover cake covered tightly with plastic wrap or in an airtight container in the refrigerator. It will stay fresh and maintain its perfect mousse texture for up to 3 days, making it a convenient dessert to enjoy over several occasions.
Freezing
If you want to save the cake for longer, it freezes wonderfully. Wrap it securely in plastic wrap followed by aluminum foil to prevent freezer burn. Thaw in the refrigerator overnight before serving to keep the mousse silky and the crust crisp.
Reheating
This dessert is best enjoyed chilled, so reheating is not recommended. If you prefer a slightly softer texture, just let the cake sit at room temperature for 10 to 15 minutes before slicing and serving to take the chill off gently.
FAQs
Can I use frozen blueberries instead of fresh?
Yes, frozen blueberries work well for the compote. Just thaw them completely and drain any excess liquid before cooking to avoid a watery texture.
What can I substitute for gelatin?
Agar-agar powder is a great plant-based substitute for gelatin. Use about half the amount and follow the package instructions for blooming and dissolving.
Can I make the crust gluten-free?
Absolutely! Use a gluten-free all-purpose flour blend and ensure it has a similar protein content for the best results in the crust texture.
How long does the mousse cake need to chill?
Chilling for at least 4 hours is key for the mousse to fully set and the flavors to meld beautifully. Overnight chilling works even better.
Is this recipe suitable for a large gathering?
Yes, the Lemon Blueberry Shortbread Mousse Cake Recipe can be scaled up easily by doubling or tripling the ingredients, making it a fantastic choice for parties or celebrations.

Ingredients
Shortbread Crust
- 1 1/2 cups all-purpose flour
- 1/2 cup powdered sugar
- 1/2 cup unsalted butter, cold and cubed
- Pinch of salt
Lemon Mousse
- 1 cup heavy cream
- 1/2 cup granulated sugar
- Zest of 2 lemons
- 1/2 cup fresh lemon juice
- 1 tablespoon gelatin powder
- 2 tablespoons water
- 8 ounces cream cheese, softened
Blueberry Compote
- 2 cups fresh blueberries
- 1/4 cup granulated sugar
- 1 tablespoon fresh lemon juice
Instructions
- Prepare the Shortbread Crust: Preheat your oven and prepare your pan. In a food processor, combine the all-purpose flour, powdered sugar, cold cubed butter, and a pinch of salt. Pulse until the mixture resembles coarse crumbs. Press this mixture evenly into the bottom of the prepared pan, ensuring a compact layer. Bake for 15-18 minutes or until lightly golden. Remove from the oven and let it cool completely before proceeding.
- Make the Lemon Mousse: In a small saucepan, gently heat the fresh lemon juice until warm. Stir in the bloomed gelatin powder (mixed previously with 2 tablespoons of water) until fully dissolved. Allow this mixture to cool to room temperature. In a large bowl, 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 gradually add the cooled lemon juice and gelatin mixture while beating continuously. Gently fold in the whipped cream until well combined, forming a light lemon mousse.
- Prepare the Blueberry Compote: In a saucepan over medium heat, combine fresh blueberries, sugar, and lemon juice. Cook while stirring occasionally for 5-7 minutes until the blueberries soften and release their juices, creating a thick compote. Let this cool completely to room temperature.
- Assemble the Mousse Cake: Spoon half of the cooled blueberry compote evenly over the cooled shortbread crust. Spread the remaining lemon mousse gently on top of the compote layer. Then, finish by spreading the remaining blueberry compote evenly over the top. Place the assembled cake in the refrigerator to chill and set for at least 4 hours.
- Serve: Once set, slice the mousse cake and serve chilled. Optionally, garnish with fresh blueberries and a sprig of mint for an elegant presentation.
Notes
- Ensure the shortbread crust is completely cooled before adding the mousse to prevent melting.
- Bloom gelatin properly in cold water before heating with lemon juice for best texture.
- Use fresh lemon juice and zest for a bright, natural lemon flavor.
- Allow the blueberry compote to cool fully before layering to maintain mousse consistency.
- Chill the assembled dessert for at least 4 hours or overnight for optimal setting.
