Preheat your oven to 350°F (175°C). Line a 9x13 inch baking pan with parchment paper, leaving an overhang for easy removal.
In a medium bowl, combine graham cracker crumbs and sugar for the crust. Mix until evenly blended.
Pour in the melted butter and stir with a spatula until the crumbs are coated and mixture resembles wet sand.
Press the crumb mixture firmly into the bottom of the prepared pan to create an even crust. Bake for 8-10 minutes until slightly fragrant and set.
While the crust cools slightly, place the cream cheese in a large bowl and beat until smooth and fluffy.
Add sugar, eggs, cinnamon, ginger, and salt to the cream cheese; beat until well combined and the mixture is smooth.
Fold in the roasted pumpkin puree gently until fully incorporated, resulting in a smooth, orange-hued batter.
Pour the pumpkin cheesecake batter over the cooled crust, spreading evenly with a spatula and smoothing the top.
Bake for 40-45 minutes, or until the edges are set and the top has developed a slight crack and a crackled appearance.
Once baked, allow the bars to cool in the pan for about 30 minutes, then transfer to the fridge to chill for at least 2 hours or until firm.
Slice into squares and serve, optionally dusted with additional cinnamon for a finishing touch. Enjoy the creamy, spiced pumpkin flavor with each bite!
