Step 1: Prepare the Crust

1. Preheat your oven to 350°F (175°C). Line a 9×9-inch (23x23cm) baking pan with parchment paper, leaving some overhang for easy removal.
2. In a medium bowl, mix the graham cracker crumbs, sugar, and melted butter until the mixture resembles wet sand.
3. Press the mixture firmly into the bottom of the prepared pan to form an even crust.
4. Bake the crust for 8–10 minutes, then set it aside to cool slightly.

Step 2: Make the Cheesecake Filling

1. In a large mixing bowl, beat the cream cheese and sugar together until smooth and creamy.
2. Add the eggs one at a time, mixing well after each addition.
3. Mix in the lemon juice, lemon zest, and vanilla extract until fully incorporated.

Step 3: Assemble and Bake

1. Pour the cheesecake filling over the cooled crust and spread it evenly.
2. Bake in the preheated oven for 25–30 minutes, or until the center is just set and slightly jiggly.
3. Remove from the oven and let the cheesecake cool to room temperature, then refrigerate for at least 4 hours or overnight.

Step 4: Prepare the Lemon Glaze (Optional)

1. In a small bowl, whisk together the powdered sugar and lemon juice until smooth.
2. Drizzle the glaze over the chilled cheesecake squares before serving.

Serving Suggestions
