01 - Combine graham cracker crumbs and melted butter in a bowl until evenly moistened. Press mixture firmly into the base of a 9×9-inch pan to form an even layer. Refrigerate to set while preparing the filling.
02 - Beat softened cream cheese and granulated sugar together in a mixing bowl until the mixture is smooth and creamy. Incorporate lemon zest and lemon juice, mixing until fully combined.
03 - In a separate bowl, whip heavy whipping cream with an electric mixer until soft peaks form.
04 - Gently fold the whipped heavy cream into the cream cheese mixture until the filling is smooth and homogenous.
05 - Spread half of the cream filling over the chilled graham crust. Scatter 2 cups of fresh blueberries over the layer, then cover with the remaining cream filling, smoothing the top.
06 - Decorate the surface with additional blueberries and a sprinkle of lemon zest. Refrigerate for at least 4 hours, or until fully set.
07 - Slice into portions using a sharp knife. Serve chilled for optimal texture and flavor.
