🛒 Ingredients
For the Crisp Crust:
- 1 ½ cups vanilla wafer crumbs or graham cracker crumbs
- 5 tbsp unsalted butter, melted
For the Creamy Mascarpone Mousse:
- 1 package (8 oz) mascarpone cheese, softened to room temperature
- 1 cup heavy whipping cream, chilled
- ½ cup powdered sugar
- 1 tsp vanilla bean paste (giving the mousse those delicate specks seen in image_a2c95d.jpg)
- 1 tsp fresh lemon zest
- 1 packet (approx. 2 ½ tsp) unflavored gelatin powder dissolved in 3 tbsp cold water
For the Glossy Blueberry Topping:
- 2 cups fresh blueberries, rinsed and dried thoroughly
- ⅓ cup blueberry jam or clear neutral glaze, melted
- 1 tbsp lemon juice
👩🍳 Instructions
Step 1: Set the Crust Base
Line the bottom of a 7-inch or 8-inch springform pan (or a pastry ring) with parchment paper. In a medium bowl, combine the cookie crumbs and melted butter until well mixed. Press the crumbs firmly into the bottom of the pan to create a solid, level crust. Place in the freezer for 10 minutes to lock it in place.
Step 2: Melt the Gelatin
Allow the unflavored gelatin powder to sit in the 3 tablespoons of cold water for 5 minutes until bloomed and thick. Microwave it for 10 to 12 seconds just until completely liquefied. Do not let it boil.
Step 3: Whip the Mousse Core
In a large mixing bowl, beat the softened mascarpone cheese, powdered sugar, lemon zest, and vanilla bean paste until completely smooth and velvety. In a separate chilled bowl, whip the heavy cream to stiff peaks. Gently fold the whipped cream into the mascarpone mixture. While folding, slowly stream in the liquid gelatin, mixing thoroughly to ensure a smooth, uniform set.
Step 4: Pour and First Chill
Pour the airy mousse batter directly over your chilled crust, smoothing the surface flat with a spatula. Place it in the refrigerator to chill and set for at least 3 to 4 hours.
Step 5: Glaze the Berry Crown
In a medium bowl, gently toss the whole fresh blueberries with the melted blueberry jam (or neutral glaze) and lemon juice until every single berry is heavily coated and glossy.
Step 6: Assemble and Serve
Once the mousse is completely firm, carefully spoon the glazed blueberries over the top of the cake, packing them close together to create a dense, glittering dome of fruit, exactly like the presentation in image_a2c95d.jpg. Return to the fridge for another 30 minutes to lock everything in place. Run a warm thin knife gently around the inside edge of the pan before releasing the springform ring. Slice and enjoy cold!
