1. Preheat your oven to 325°F (165°C). Line a 9×9-inch baking dish with parchment paper, leaving some overhang for easy removal.
2. In a bowl, combine the graham cracker crumbs, melted butter, and 1/4 cup sugar. Press the mixture firmly into the bottom of the prepared baking dish to form the crust.
3. Bake the crust for about 10 minutes. Remove from the oven and let it cool while you prepare the filling.
4. In a large mixing bowl, beat the softened cream cheese until smooth and creamy. Add 1 cup of sugar and continue to beat until well combined.
5. Mix in the eggs, one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract, sour cream, flour, and salt until the mixture is smooth.
6. Pour the cream cheese mixture over the cooled crust, spreading it evenly with a spatula.
7. Bake for 35-40 minutes, or until the center is set and the edges are lightly golden. Allow the cheesecake to cool completely in the pan before cutting into squares.
8. Refrigerate for at least 2 hours before serving, as this helps the flavors meld together, creating that perfect cheesecake experience.

Remember, patience is key. As my grandmother always said, “Good things come to those who wait,” and these squares are worth every minute.
