Preheat oven to 160°C / 325°F. Line the base of a springform pan with parchment paper.
Crush gingersnap cookies into fine crumbs, mix with melted butter, and press firmly into pan bottom. Chill while preparing filling.
Beat cream cheese and sugars until smooth. Add pumpkin puree, sour cream, spices, and vanilla; continue mixing until creamy.
Incorporate eggs one by one, mixing just until combined. Avoid overmixing to prevent cracks later.
Pour batter over crust. Tap lightly to remove air bubbles. Place pan on a rimmed baking sheet.
Bake for about 55–65 minutes, until edges are set but center jiggles slightly.
Turn off oven, open door slightly, and let cheesecake cool inside for 1 hour. Then refrigerate at least 6 hours or overnight.
Before serving, decorate with whipped cream, caramel drizzle, or a sprinkle of cinnamon for a festive finish.
