Prepare the crust by mixing graham cracker crumbs and melted butter.
Press the crust mixture into the bottom of a springform pan.
In a mixing bowl, beat the softened cream cheese until smooth.
Add pumpkin puree, powdered sugar, vanilla extract, and pumpkin spice to the cream cheese.
In a separate bowl, whip the heavy cream until stiff peaks form.
Gently fold the whipped cream into the pumpkin mixture until fully incorporated.
Pour the filling into the prepared crust and smooth the top.
Refrigerate the cheesecake for at least 4 hours, preferably overnight.
