Preheat your oven to 325°F (160°C). Grease a 9x9-inch baking pan and line it with parchment paper, leaving an overhang for easy removal.
In a medium bowl, combine the graham cracker crumbs, melted butter, and 2 tablespoons of sugar. Mix until the crumbs are evenly coated. Press the mixture firmly into the bottom of the prepared pan to form an even layer.
Place the pan in the preheated oven and bake for 10 minutes. Remove from the oven and set aside to cool slightly.
In a large mixing bowl, beat the softened cream cheese and 1 cup of sugar with an electric mixer until smooth and creamy, about 2 minutes.
Add the eggs one at a time, mixing well after each addition. Then mix in the vanilla extract, lemon zest, and fresh lemon juice, blending until fully incorporated.
In a small bowl, toss the fresh blueberries with 1 tablespoon of cornstarch. This will help thicken the filling and prevent the blueberries from sinking.
Gently fold the blueberries into the cheesecake mixture, taking care not to break them.
Pour the cheesecake filling over the pre-baked crust, spreading it evenly.
Bake in the preheated oven for 35-40 minutes or until the center is set and the edges are slightly puffed but not cracked.
Once baked, remove from the oven and let it cool at room temperature. Once cooled, refrigerate for at least 3 hours, or until fully chilled.
Lift the bars out of the pan using the parchment overhang. Slice into squares or rectangles. Dust with powdered sugar before serving for an elegant touch.
