Crush graham crackers into fine crumbs using a food processor or by sealing them in a plastic bag and pounding with a rolling pin. Mix crumbs with sugar and melted butter until evenly coated and crumbly. Press the mixture firmly into the bottom of a springform pan to create an even crust; set aside.
In a large mixing bowl, beat the softened cream cheese with a hand or stand mixer until smooth and creamy, about 2-3 minutes. Add pumpkin purée, granulated sugar, and maple syrup or honey, and continue to beat until well combined.
Add ground cinnamon, ginger, and nutmeg to the pumpkin mixture, and stir until fragrant and evenly distributed. This creates the warm spice flavor that defines the cheesecake.
In a separate bowl, whip the chilled heavy cream until stiff peaks form, about 3-4 minutes. This adds airy richness to the filling.
Gently fold the whipped cream into the pumpkin mixture using a rubber spatula, incorporating it gradually to keep the filling light and fluffy.
Pour the creamy pumpkin filling over the prepared crust, smoothing the top with a spatula for an even surface. Tap the pan gently on the counter to release any air bubbles.
Cover the pan with plastic wrap and chill in the refrigerator for at least 4 hours, preferably overnight, to allow the cheesecake to set and develop flavor.
Once chilled and firm, release the sides of the springform pan and transfer the cheesecake to a serving platter. Decorate as desired with whipped cream, cinnamon dusting, or pumpkin seeds.
