Ingredients

For the 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

For the 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

For the Blueberry Compote:

8 ounces cream cheese, softened
2 cups fresh blueberries
1/4 cup granulated sugar
1 tablespoon fresh lemon juice

How to Make Lemon Blueberry Shortbread Mousse Cake

Step 1: Prepare the Shortbread Crust

Combine the all-purpose flour, powdered sugar, unsalted butter, and a pinch of salt in a food processor. Pulse until it resembles coarse crumbs.
Press the mixture evenly into the bottom of your prepared pan.
Bake for 15-18 minutes or until lightly golden. Allow it to cool completely.

Step 2: Prepare the Lemon Mousse

In a saucepan over low heat, warm the lemon juice. Once warm, stir in the bloomed gelatin powder, ensuring it dissolves fully. Let it cool to room temperature.
In a mixing bowl, beat together the heavy cream, granulated sugar, and lemon zest. Continue beating until stiff peaks form.
In another bowl, whip the softened cream cheese. Gradually add in the cooled lemon juice mixture while continuing to beat until smooth.
Fold in the whipped cream gently until well combined.

Step 3: Assemble and Chill

Pour half of the lemon mousse over the cooled shortbread crust.
Spread half of the fresh blueberries evenly on top of the mousse layer.
Add remaining mousse on top and smooth it out with a spatula.
Cover and refrigerate for at least 4 hours or until set.

Step 4: Serve Your Dessert

Once set, run a knife around the edge of your pan to loosen it gently.
Carefully remove sides from your pan before slicing into portions.
Serve chilled and enjoy every delicious bite of your Lemon Blueberry Shortbread Mousse Cake!

How to Serve Lemon Blueberry Shortbread Mousse Cake

Serving your Lemon Blueberry Shortbread Mousse Cake can elevate not only the presentation but also the overall dessert experience. Here are some creative ways to enjoy this delightful treat.

Family Style

Serve the cake in a sliced form on a large platter. This allows everyone to take their portion while showcasing the beautiful layers of mousse and blueberries.

Individual Portions

For a more elegant touch, serve individual slices on dessert plates. Garnish each slice with a sprig of mint or a dusting of powdered sugar for added flair.

With Fresh Berries

Top each slice with additional fresh blueberries or raspberries. This enhances the berry flavor and adds a pop of color to your dessert presentation.

Accompanied by Whipped Cream

Serve alongside a dollop of freshly whipped cream. The creaminess complements the zesty lemon mousse beautifully.

Paired with Ice Cream

A scoop of vanilla or lemon sorbet beside the cake can create a refreshing contrast, perfect for warm days.

How to Perfect Lemon Blueberry Shortbread Mousse Cake

To ensure your Lemon Blueberry Shortbread Mousse Cake turns out perfectly every time, consider these helpful tips.

Use cold ingredients: Ensure your butter and cream cheese are cold for the best texture in your shortbread crust and mousse.
Bloom gelatin correctly: Always bloom gelatin in water before adding it to warm liquids to ensure it dissolves properly.
Beat heavy cream well: Whip the heavy cream until stiff peaks form, as this adds volume and lightness to your mousse.
Cool completely: Let the shortbread crust cool completely before adding the mousse layer to prevent melting.
Chill adequately: Refrigerate the cake for at least 4 hours, or overnight if possible, for optimal set and flavor melding.
Garnish creatively: Use fresh zest or edible flowers as garnishes for an appealing finish that enhances presentation.

Common Mistakes to Avoid

When making your Lemon Blueberry Shortbread Mousse Cake, it’s easy to slip up. Here are some common mistakes to be aware of.

Skipping the chilling time: This cake needs adequate time to set in the fridge. Don’t rush it; allow at least 4 hours for the mousse to firm up properly.
Not measuring ingredients accurately: Baking is a science. Use precise measurements for flour, sugar, and butter to ensure the right texture and flavor.
Overmixing the mousse: Be gentle when folding the whipped cream into the lemon mixture. Overmixing can deflate the mousse, leading to a heavier texture.
Ignoring ingredient temperatures: Ensure that your butter and cream cheese are at room temperature. This helps them blend smoothly into the batter without lumps.
Underbaking the crust: A golden-brown shortbread crust provides a solid base. Keep an eye on it while baking to avoid an undercooked crust.
