Preheat your oven to 325°F (160°C) and line a 9x13 inch baking dish with parchment paper, leaving some overhang for easy removal later.
In a medium bowl, combine the graham cracker crumbs, melted butter, and 2 tablespoons of sugar. Mix until the crumbs are fully embedded with the butter. Press this mixture firmly into the bottom of the prepared baking dish to form an even layer.
Place the crust in the preheated oven and bake for 10 minutes. Remove and allow it to cool slightly while preparing the filling.
In a large mixing bowl, beat the softened cream cheese with ½ cup granulated sugar until smooth and creamy. Add the eggs one at a time, mixing well after each addition. Incorporate the vanilla extract and orange zest, mixing just until combined.
In a separate bowl, toss the cranberries with cornstarch and orange juice to coat them evenly. This will help keep them from sinking to the bottom during baking. Gently fold the cranberries into the cream cheese mixture.
Pour the cream cheese and cranberry mixture over the cooled crust, spreading it evenly. Drop spoonfuls of cranberry sauce over the top and swirl with a knife for a marbled effect.
Return the pan to the oven and bake for an additional 30-35 minutes or until the center is set but still has a slight jiggle.
Once done, let the bars cool at room temperature for about 1 hour. Then, refrigerate for at least 2 hours to allow them to set properly.
Once chilled, lift the cheesecake out of the pan using the parchment overhang. Cut into squares and serve chilled or at room temperature.
Notes
Dust the top with powdered sugar before serving and garnish with fresh cranberry and a slice of orange for an extra pop of color and flavor.
