Lightly grease a 9-inch springform pan or line the bottom with parchment paper.
In a medium bowl, stir together the graham cracker crumbs, brown sugar, cinnamon, and salt.
Add the melted butter and mix until the crumbs are evenly moistened.
Press the mixture firmly into the bottom and about 1 inch up the sides of the prepared pan.
Refrigerate the crust for at least 20 minutes.
Pour the cold heavy cream into a chilled mixing bowl. Beat on medium-high speed until stiff peaks form. Refrigerate while preparing the remaining filling.
In a separate large bowl, beat the softened cream cheese for two to three minutes, or until completely smooth.
Add the powdered sugar and brown sugar. Beat until creamy, stopping to scrape the bowl as needed.
Add the pumpkin puree, vanilla, pumpkin pie spice, cinnamon, and salt. Mix on low speed until combined.
Fold one-third of the whipped cream into the pumpkin mixture.
Gently fold in the remaining whipped cream in two additions. Stop mixing once the filling is uniform and no white streaks remain.
Spoon the filling into the chilled crust and smooth the top.
Cover and refrigerate for at least 8 hours, preferably overnight.
Run a thin knife around the edge of the cheesecake before releasing the springform pan.
Decorate with whipped cream, cookie crumbs, pecans, caramel, or cinnamon.
Slice with a clean, sharp knife and serve chilled.
