Preheat the Oven: Start by preheating your oven to 350°F (175°C).

Prepare the Crust: In a medium bowl, mix the graham cracker crumbs, melted butter, and granulated sugar. Press this mixture into an even layer at the bottom of a 9×13 inch baking dish.

Bake the Crust: Place the crust in the preheated oven and bake for about 10 minutes, until it’s lightly golden.

Whip Up the Filling: In a large mixing bowl, combine the softened cream cheese and powdered sugar, beating until smooth and creamy. Then, add the eggs one at a time, fully incorporating each egg before adding the next. Mix in the fresh lemon juice and zest until everything is well combined.

Pour and Bake Again: Pour the lemon filling over the baked crust and return it to the oven. Bake for an additional 25-30 minutes, or until the center is set but still slightly jiggly.

Cool and Serve: Allow the bars to cool at room temperature, then chill them in the fridge for at least 2 hours before slicing. Dust with powdered sugar right before serving.
