Ingredients

Scale

Shortbread Crust:

  • 1 1/2 cups all-purpose flour
  • 1/2 cup powdered sugar
  • 1/2 cup unsalted butter, cold and cubed
  • 1 pinch salt

Lemon Mousse Ingredients:

  • 8 ounces (226 grams) cream cheese, softened
  • 1 cup heavy cream
  • 1/2 cup granulated sugar
  • 1/2 cup fresh lemon juice
  • 2 lemons zest
  • 1 tablespoon gelatin powder
  • 2 tablespoons water

Blueberry Compote:

  • 2 cups fresh blueberries
  • 1/4 cup granulated sugar
  • 1 tablespoon fresh lemon juice

Instructions

  1. Prepare the foundational shortbread layer by blending flour, powdered sugar, butter, and salt in a food processor until crumbly texture emerges.
  2. Transfer the mixture into a parchment-lined springform pan, pressing firmly and evenly across the bottom to create a uniform base.
  3. Roast the shortbread crust in a preheated 350°F oven for 15-18 minutes until edges transform into a delicate golden hue, then allow complete cooling.
  4. Activate gelatin by sprinkling over water, letting it hydrate and transform for several minutes.
  5. Gently warm lemon juice in a saucepan, incorporating dissolved gelatin until seamlessly integrated, then cool to ambient temperature.
  6. Whip heavy cream with granulated sugar and lemon zest, developing robust, dramatic peaks that hold their shape elegantly.
  7. Cream cheese receives gentle manipulation until silky smooth, gradually welcoming the lemon-gelatin mixture while maintaining consistent beating.
  8. Delicately fold whipped cream into the lemon cream cheese base, creating a luminous, airy mousse with harmonious flavor profiles.
  9. Craft blueberry compote by simmering fresh berries with sugar and lemon juice, allowing fruits to soften and release vibrant juices for 5-7 minutes.
  10. Layer the chilled shortbread foundation with alternating stripes of lemon mousse and blueberry compote, concluding with a compelling compote crown.
  11. Refrigerate the assembled dessert for minimum 4 hours, allowing flavors to meld and structure to solidify completely.
  12. Prior to serving, release cake edges using a precise knife stroke, unmold carefully, and present the chilled masterpiece.

Notes

  • Choose cold butter directly from the refrigerator to ensure a crumbly, flaky shortbread crust that holds its shape perfectly.
  • Zest lemons carefully to avoid the bitter white pith, using only the bright yellow outer layer for maximum citrusy flavor.
  • Freeze the cake pan before pressing the shortbread crust to help prevent butter from melting and maintain a crisp texture.
  • Drain excess liquid from blueberry compote to prevent a watery layer that could compromise the mousse cake’s structural integrity.
