Ingredients

Scale

Main Ingredients:

  • 2 cups fresh blueberries
  • 1 ½ cups all-purpose flour
  • 1 cup heavy cream
  • 8 ounces cream cheese
  • ½ cup unsalted butter

Supporting Ingredients:

  • ½ cup powdered sugar
  • ½ cup granulated sugar
  • ½ cup fresh lemon juice
  • 1 tablespoon gelatin powder
  • 1 tablespoon fresh lemon juice
  • Zest of 2 lemons

Finishing Ingredients:

  • ¼ cup granulated sugar
  • Pinch of salt
  • 2 tablespoons water

Instructions

  1. Mix 1 ½ cups flour, ½ cup powdered sugar, ½ cup cold cubed butter, and a pinch of salt in a food processor until crumbly.
  2. Transfer the mixture into a 9-inch springform pan, pressing firmly to create an even base.
  3. Bake the crust at 350°F for 15-18 minutes until edges turn golden brown. Cool completely on a wire rack.
  4. Sprinkle 1 tablespoon gelatin over 2 tablespoons water and let sit for 5 minutes to bloom.
  5. Warm ½ cup lemon juice in a saucepan over low heat, then remove and stir in the bloomed gelatin. Let cool to room temperature.
  6. Whip 1 cup heavy cream with ½ cup granulated sugar and lemon zest until stiff peaks form.
  7. Beat 8 ounces softened cream cheese until smooth, then gradually mix in the cooled lemon juice and gelatin.
  8. Gently fold the whipped cream into the cream cheese mixture until fully incorporated.
  9. Combine 2 cups blueberries, ¼ cup sugar, and 1 tablespoon lemon juice in a saucepan over medium heat.
  10. Cook the blueberries for 5-7 minutes, stirring occasionally, until they soften and release juices. Cool to room temperature.
  11. Spread half the lemon mousse evenly over the cooled shortbread crust.
  12. Spoon a layer of blueberry compote directly on top of the mousse.
  13. Add the remaining lemon mousse and smooth the surface with a spatula.
  14. Decorate the top with additional blueberry compote.
  15. Refrigerate for 4 hours or overnight until the mousse sets completely.
  16. Carefully remove from the springform pan, slice, and serve chilled.

Notes

  • Shortbread crust works best when butter is cold and ingredients are pulsed just until they barely come together.
  • Gelatin needs careful handling – sprinkle it evenly and let it absorb water completely before heating to prevent lumps.
  • Whipping cream requires chilled bowl and beaters for maximum volume and stable peaks that hold their shape.
  • Blueberry compote can be prepared ahead and stored in the refrigerator for several days, making meal prep easier and more flexible.
