# What You'll Need:
→ Crust
01 - 7 ounces graham crackers or digestive biscuits, finely crushed
02 - 6 tablespoons unsalted butter, melted
03 - 2 tablespoons granulated sugar
→ Cheesecake Layer
04 - 14 ounces cream cheese, softened
05 - 1 cup powdered sugar
06 - 1 cup heavy cream, chilled
07 - 2 tablespoons freshly squeezed lemon juice
08 - 1 teaspoon finely grated lemon zest
09 - 1 teaspoon pure vanilla extract
→ Blueberry Swirl
10 - 1 1/2 cups fresh or frozen blueberries
11 - 2 tablespoons granulated sugar
12 - 1 tablespoon lemon juice
13 - 1 teaspoon cornstarch mixed with 2 teaspoons water
# How To Make It:
01 - Line a 9x9-inch square baking pan with parchment paper, ensuring an overhang on all sides for easy removal.
02 - In a medium bowl, combine crushed biscuits with melted butter and sugar. Mix until the crumbs are evenly coated. Press the mixture firmly and evenly into the base of the prepared pan. Refrigerate while you prepare the filling.
03 - In a small saucepan, combine blueberries, sugar, and lemon juice. Cook over medium heat, stirring, until the berries burst and release their juices, about 5–7 minutes. Stir in the cornstarch slurry and simmer for 1–2 minutes until thickened. Remove from heat and allow to cool completely.
04 - Using an electric mixer or whisk, beat softened cream cheese with powdered sugar until smooth and lump-free. Add lemon juice, lemon zest, and vanilla extract, mixing thoroughly.
05 - In a separate bowl, whip the cold heavy cream to stiff peaks. Gently fold the whipped cream into the cream cheese mixture until fully incorporated and airy.
06 - Spread the cheesecake filling evenly over the chilled crust, smoothing the surface with a spatula.
07 - Drop spoonfuls of blueberry sauce onto the cheesecake layer. Using a knife or skewer, gently swirl the sauce for a marbled effect without overmixing.
08 - Cover and refrigerate for at least 4 hours, or until the cheesecake is fully set and firm.
09 - Lift the set cheesecake from the pan using the parchment overhang. Slice into 12 equal bars and serve chilled.
