Ingredients

Scale
  • 1 ½ cups (225 g) fresh or frozen blueberries
  • ¼ cup (50 g) granulated sugar
  • 1 tbsp lemon juice
  • 1 tsp cornstarch mixed with 1 tbsp water
  • 1 cup (227 g) unsalted butter, softened
  • 2 cups (240 g) all-purpose flour
  • ½ cup (60 g) powdered sugar
  • ¼ tsp salt
  • 1 tsp vanilla extract
  • 1 cup (240 ml) heavy whipping cream, cold
  • ½ cup (113 g) cream cheese, softened
  • ½ cup (60 g) powdered sugar
  • 2 tbsps fresh lemon juice
  • 1 tsp lemon zest
  • 1 tsp vanilla extract

Instructions

  1. Shortbread Base Preparation: Cream butter and powdered sugar until smooth, then gently fold in vanilla, flour, and salt to create a tender dough. Press the mixture evenly into a 9-inch springform pan, ensuring a uniform layer.
  2. Initial Baking Stage: Position the pan in a preheated oven at 350°F (175°C) and bake for 18-20 minutes until the edges turn a delicate golden hue. Remove and allow the shortbread base to cool completely, creating a crisp foundation for the dessert.
  3. Mousse Layer Construction: While the base cools, whip cream cheese until smooth, then gradually incorporate lemon zest, lemon juice, and sugar. Fold in whipped cream gently to maintain a light, airy texture that will provide a luxurious mouthfeel.
  4. Blueberry Integration: Fold fresh blueberries into the mousse mixture, distributing them evenly to ensure each slice contains bursts of fruity flavor. Carefully spread the mousse over the cooled shortbread base, creating a smooth and elegant surface.
  5. Chilling and Setting: Transfer the assembled cake to the refrigerator and allow it to set for a minimum of 4 hours or overnight. This crucial resting period will help the mousse firm up and allow the flavors to meld harmoniously.
  6. Final Garnishing: Before serving, delicately dust the top with powdered sugar and scatter additional fresh blueberries for a vibrant, appetizing presentation that highlights the cake’s elegant composition.

Notes

  • Ensure butter is at room temperature for smooth, uniform mixing and press dough firmly and evenly into pan to create a solid shortbread base.
  • Watch closely during baking and remove when edges turn light golden to maintain a tender, melt-in-your-mouth texture without burning.
  • Let shortbread cool completely before adding mousse layer to prevent soggy crust and maintain crisp, delicate shortbread structure.
  • Consider adding lemon zest to shortbread dough for extra citrusy brightness that complements blueberry and creates more complex taste profile.
