Prep the pan: Line the bottom of a 9-inch springform pan with parchment paper and lightly grease the sides for easy release.
Make the crust: In a bowl, combine crushed gingersnaps, melted butter, sugar, and a pinch of salt. Stir until the texture is like wet sand and holds together when pressed.
Press and chill: Pour the crumbs into the pan and press firmly into an even base, pushing slightly up the sides. Use the bottom of a measuring cup to compact.
Chill in the fridge while you make the filling.
Beat the cream cheese: In a large bowl, beat softened cream cheese with powdered sugar until smooth and lump-free, about 2 minutes. Scrape the bowl.
Add flavor: Beat in molasses, vanilla, ginger, cinnamon, nutmeg, cloves (if using), and salt until fully combined and silky.
Whip the cream: In a separate cold bowl, whip the heavy cream to stiff peaks. Don’t overbeat—it should look smooth and hold a firm peak.
Fold it in: Gently fold the whipped cream into the cream cheese mixture in two additions.
Use a spatula and light motions to keep the filling airy.
Fill the crust: Spoon the mixture into the crust and smooth the top with an offset spatula. Tap the pan gently on the counter to release air bubbles.
Chill to set: Cover and refrigerate for at least 6 hours, preferably overnight, until firm enough to slice cleanly.
Garnish and serve: Run a thin knife around the edge, release the springform, and top with whipped cream, crushed cookies, or a caramel drizzle. Slice with a warm, clean knife.
