Prepare Crust: Crush graham crackers in a food processor or in a ziplock bag with a rolling pin. Mix crushed graham cracker crumbs, sugar, and cinnamon in a bowl. Add melted butter and stir until it resembles wet sand. Press into an 8-inch springform pan to form a crust. Bake for 10 minutes and let cool.
Prepare Filling: Beat softened cream cheese with both sugars in a large bowl until creamy, about 2–3 minutes. Add pumpkin puree, heavy cream, vanilla, pumpkin pie spice, and salt. Mix until smooth. Gently add eggs one at a time, mixing just enough to combine to avoid over-mixing. Pour filling into cooled crust and smooth the top.
Bake Cheesecake: Place springform pan in 10-inch cake pan and place inside a roasting pan, or lasagna pan. Add hot water to pan high enough that it doesn't spill into the cake pan protecting the cheesecake - this helps prevent cracks. Bake at 350°F for 70–80 minutes until edges set and center jiggles slightly. Turn off oven, crack the door, and let cheesecake cool inside for at least 1 hour before removing.
Chill Cheesecake: Remove cheesecake from water bath, cool fully at room temperature, cover, and chill in fridge for at least 4 hours or overnight.
Prepare Stabilized Whipped Cream: Combine heavy cream, xanthan gum, powdered sugar, and vanilla in a chilled bowl. Whip until stiff peaks form, avoiding overwhipping. Transfer to a piping bag with a star tip.
Assemble and Serve: Run a knife around cheesecake edge and remove springform ring. Pipe whipped cream in swirls on top. Dust with cinnamon. Slice with a warm knife and serve chilled.
