01 - In a medium bowl, combine graham cracker crumbs, melted butter, 2 tablespoons sugar, and lemon zest. Mix until well blended and evenly moistened. Press the mixture firmly into the bottom of a 9-inch springform pan, creating an even layer. Place in the refrigerator while preparing the filling.
02 - In a large bowl, beat the cream cheese and 3/4 cup sugar until smooth and creamy, approximately 2-3 minutes. Add lemon juice, lemon zest, and vanilla extract; mix until fully combined and no lumps remain.
03 - In a separate chilled bowl, whip the cold heavy cream using a hand mixer or stand mixer until stiff peaks form. Be careful not to overwhip.
04 - Gently fold the whipped cream into the cream cheese mixture using a spatula, being careful to maintain the airy texture. Fold until fully incorporated and no white streaks remain.
05 - Carefully fold in 1 2/3 cups fresh blueberries, taking care not to crush them. Gently distribute the berries throughout the filling.
06 - Pour the filling over the chilled crust. Smooth the top with a spatula, creating an even surface. Tap the pan gently on the counter to release any air bubbles.
07 - Cover the springform pan with plastic wrap or foil. Refrigerate the cake for at least 4 hours, or until completely set and firm to the touch.
08 - Before serving, carefully release the springform ring and remove the cake from the pan. Arrange the remaining 3/4 cup fresh blueberries on top, sprinkle with lemon zest, and add whipped cream garnish if desired.
