Preheat your oven to 325°F (160°C). Prepare an 8x8 inch baking dish by lining it with parchment paper, ensuring you leave some overhang on the sides for easy lifting later.
In a medium mixing bowl, combine the graham cracker crumbs, melted butter, and 2 tablespoons of granulated sugar. Stir until the mixture resembles wet sand and is fully moistened. Press this mixture firmly and evenly into the bottom of the prepared baking dish to form a solid crust.
Bake the crust in the preheated oven for approximately 10 minutes, or until lightly golden. Once baked, remove it from the oven and allow it to cool for a few minutes while preparing the cheesecake filling.
In a large mixing bowl, use an electric mixer to beat the softened cream cheese and ¾ cup of granulated sugar together until the mixture is smooth, creamy, and free of lumps, typically about 2-3 minutes.
Incorporate the eggs one at a time, mixing well after each addition to ensure they're fully integrated. Next, add the lemon zest, freshly squeezed lemon juice, and vanilla extract, mixing until everything is well combined and smooth.
Gently fold the fresh blueberries into the cheesecake mixture using a spatula or wooden spoon. Be careful to avoid crushing the blueberries to maintain their shape.
Pour the cheesecake filling onto the cooled crust, spreading it out evenly. Place the dish back into the oven and bake for 25-30 minutes, or until the edges are set but the center remains slightly jiggly.
Once finished baking, let the bars cool to room temperature in the baking dish. After they have cooled, transfer the dish to the refrigerator and chill for at least 4 hours, or preferably overnight, to allow the cheesecake to set completely.
Once fully chilled, use the parchment paper overhang to lift the cheesecake out of the baking dish. Cut into squares or rectangles, and dust with powdered sugar if desired for an added touch of sweetness.
Notes
Dust with powdered sugar before serving for an added touch of sweetness.
