Ingredients

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

Instructions

  1. Prepare Base: Blend softened butter with powdered sugar until creamy. Mix in vanilla, flour, and salt to form a cohesive dough. Press evenly into a greased springform pan.
  2. Bake Shortbread: Preheat oven to 350°F. Bake shortbread until edges turn golden amber, approximately 15-18 minutes. Cool completely at room temperature.
  3. Create Mousse Foundation: Whip heavy cream to soft peaks. In a separate bowl, blend cream cheese, powdered sugar, lemon juice, zest, and vanilla until smooth and uniform.
  4. Assemble Mousse Layer: Gently fold whipped cream into lemony cream cheese mixture, creating a light, airy mousse. Spread evenly over cooled shortbread crust.
  5. Develop Blueberry Compote: Simmer blueberries with sugar and lemon juice. Introduce cornstarch slurry to thicken sauce, stirring until glossy. Cool completely.
  6. Final Composition: Pour cooled blueberry compote over mousse layer. Refrigerate for minimum two hours to set flavors and textures.
  7. Serve: Slice and present the multi-layered dessert, showcasing its elegant composition of buttery, tangy, and fruity elements.

Notes

  • Butter Temperature Trick: Ensure butter is softened at room temperature for smooth, even mixing in shortbread dough, preventing lumpy or tough texture.
  • Crust Pressing Technique: Use the back of a spoon or flat-bottomed glass to press shortbread dough evenly, creating a uniform, compact base that bakes consistently.
  • Cream Whipping Precision: Whip heavy cream just until soft peaks form to maintain structure and prevent over-beating, which can lead to a grainy mousse texture.
  • Blueberry Compote Control: Watch compote closely while simmering, stirring frequently to prevent burning and achieve a perfect glossy consistency without scorching.
