01 - In a medium bowl, combine graham cracker crumbs with melted butter until evenly moistened. Press the mixture firmly into the bottom of a 9 x 9-inch pan to create a level crust. Refrigerate while preparing the filling.
02 - In a separate large bowl, beat softened cream cheese with granulated sugar using a hand mixer until perfectly smooth. Add lemon zest and fresh lemon juice, then mix to incorporate.
03 - In another bowl, whip the heavy cream until soft peaks form. Gently fold the whipped cream into the cream cheese mixture, taking care not to deflate the whipped texture.
04 - Spread half of the lemon cream filling evenly over the chilled graham cracker crust. Distribute fresh blueberries generously over the filling layer. Cover the blueberries with the remaining cream layer, smoothing the top.
05 - Refrigerate the assembled cake for at least 4 hours, or overnight for best results. Before serving, garnish with additional fresh blueberries and lemon zest.
06 - Slice the chilled dessert into portions and serve immediately.
