Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish.

In a medium bowl, combine graham cracker crumbs, ½ cup granulated sugar, and melted butter. Mix until well combined. Press the mixture evenly into the bottom of the prepared baking dish to form the crust.

In a large mixing bowl, beat the softened cream cheese with an electric mixer until smooth. Gradually add in the powdered sugar and vanilla extract, mixing until well combined. Add the eggs one at a time, mixing until just incorporated after each addition.

Pour the cream cheese mixture over the prepared crust, spreading it evenly. In a small bowl, mix together the ground cinnamon and 1 tablespoon of granulated sugar. Sprinkle this mixture evenly over the cheesecake layer.

Bake in the preheated oven for 30-35 minutes, or until the edges are set and the center is slightly jiggly. Remove from the oven and let cool at room temperature for about 30 minutes. Then, refrigerate for at least 2 hours before cutting into bars.

Cut into squares and serve chilled or at room temperature.
