Ingredients
Scale
- 200g unsalted butter, softened
- 100g powdered sugar
- 250g all-purpose flour
- 1 teaspoon vanilla extract
- Zest of 2 lemons
- 300g fresh blueberries
- 2 tablespoons lemon juice
- 250g mascarpone cheese
- 200ml heavy cream
- 100g granulated sugar
- 1 teaspoon gelatin powder (optional, for mousse stability)
- Fresh blueberries and lemon zest for garnish
Instructions
- Preheat your oven to 180°C (350°F). Cream together softened unsalted butter and powdered sugar in a mixing bowl until light and fluffy. Add vanilla extract and lemon zest, mixing well.
- Gradually incorporate all-purpose flour, mixing until the dough forms. Press the dough evenly into the bottom of a parchment-lined springform pan. Bake for 15-20 minutes or until golden brown. Allow to cool completely.
- Combine fresh blueberries with lemon juice in a saucepan and heat gently until blueberries release their juices. Puree the mixture and strain to remove seeds if desired. Let cool to room temperature.
- In a mixing bowl, beat heavy cream with granulated sugar until soft peaks form. In a separate bowl, combine mascarpone cheese with cooled blueberry puree. Dissolve gelatin powder in warm water and mix it into the blueberry mixture. Gently fold in the whipped cream until smooth and creamy.
- Pour blueberry mousse over the cooled shortbread base, smoothing the top. Garnish with fresh blueberries and lemon zest. Cover with plastic wrap and refrigerate for at least 4 hours or overnight to set.
Notes
- Ensure the shortbread base cools completely before adding the mousse.
- Fresh blueberries will provide the best flavor; if using frozen, thaw and drain them properly.
- For outdoor serving or longer storage, stabilize the mousse with gelatin or agar-agar.
- Adjust the amount of lemon zest and juice based on your taste preference.
- Chill the cake well for clean slicing and well-set layers.
