Preheat your oven to 350°F (175°C). In a medium bowl, combine the graham cracker crumbs and 1/4 cup granulated sugar. Pour in the melted butter and stir until the crumbs are evenly coated and resemble wet sand. Press this mixture firmly and evenly into the bottom of your greased 9x13-inch baking pan. Bake for 8-10 minutes until set and lightly golden. Remove from the oven and let cool slightly while preparing the filling.
In a large mixing bowl, beat the softened cream cheese with an electric mixer until smooth and creamy. Add the pumpkin puree and 1 cup granulated sugar, mixing until combined. Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in vanilla extract, ground cinnamon, nutmeg, ginger, and finally the maple syrup. Mix until everything is just blended—avoid overmixing to prevent cracking.
Pour the filling over the pre-baked crust, spreading it evenly with a spatula. Bake at 350°F (175°C) for 40-45 minutes or until the edges are set and the center has a slight jiggle but is not liquid. The key is gentle baking to keep the cheesecake creamy and prevent overcooking.
Remove the bars from the oven and place the pan on a cooling rack. Let them cool completely at room temperature for about an hour, then transfer to the refrigerator for at least 4 hours or overnight. Chilling helps the bars firm up and makes slicing easier.
Use a sharp knife to cut into squares or rectangles. For clean cuts, wipe the knife with a warm, damp cloth between slices. Serve plain or drizzle a little extra maple syrup on top for added sweetness and presentation. These bars are perfect with a cup of coffee or tea for a comforting fall treat.
