In a medium bowl, combine graham cracker crumbs and melted butter. Mix until well combined.
Press the mixture firmly into the bottom of a 9-inch springform pan to form the crust. Refrigerate for 15 minutes to set.
In a large mixing bowl, beat the heavy whipping cream until stiff peaks form.
In another bowl, beat the softened cream cheese until smooth. Gradually add powdered sugar, vanilla extract, lemon juice, and lemon zest, mixing until well combined.
Gently fold the whipped cream into the cream cheese mixture until fully incorporated.
Carefully fold in the fresh blueberries, reserving a few for garnish.
Spread the cream mixture evenly over the chilled crust in the springform pan. Smooth the top with a spatula.
Cover with plastic wrap and refrigerate for at least 4 hours, or overnight for best results.
Once set, remove the cake from the springform pan. Garnish with reserved blueberries and additional lemon zest if desired. Slice and serve chilled.
