Preheat your oven to 350°F (175°C). Line an 8x8-inch baking dish with parchment paper.

Combine graham cracker crumbs, all-purpose flour, granulated sugar, and a pinch of salt. Drizzle in melted butter and mix until resembling wet sand.

Set aside one-third of the crumb mixture for topping. Press the remaining mixture into the bottom of the lined baking dish.

Beat the cream cheese until smooth, then mix in the granulated sugar. Add eggs one at a time, then fold in lemon zest, juice, and vanilla extract.

Pour the filling over the crust and sprinkle the reserved crumb mixture on top. Bake for 30-35 minutes until the center is set but slightly jiggly.

Let cool to room temperature, then refrigerate for at least 3 hours before slicing.

Slice and serve chilled, topping with fresh berries or whipped cream if desired.
