Preheat your oven to 325°F (160°C) and line a muffin tin with paper liners.
In a small bowl, combine the gingerbread cookie crumbs and melted butter. Mix until the crumbs are well coated.
Evenly distribute the crumb mixture into the lined muffin tin, pressing down firmly to create a base. Bake for 8-10 minutes until set, then remove from the oven and let cool.
In a large mixing bowl, beat the softened cream cheese with an electric mixer until creamy and smooth.
Gradually add in the granulated sugar and mix until combined.
Add the vanilla extract, ground ginger, cinnamon, and nutmeg to the cream cheese mixture and mix until everything is fully incorporated.
Beat in the eggs one at a time, mixing just until combined after each addition.
Stir in the sour cream until the mixture is smooth and creamy.
Pour the cheesecake filling over the cooled gingerbread crusts, filling each cup about 3/4 full.
Bake in the preheated oven for 20-25 minutes or until the edges are set and the centers have a slight jiggle.
Turn off the oven and crack the oven door, leaving the cheesecakes inside for an additional hour to gently cool.
Once cooled, refrigerate the cheesecakes for at least 4 hours (or preferably overnight) to firm up.
When ready to serve, top each cheesecake with whipped cream and a sprinkle of crushed gingerbread cookies.
Notes
For best results, refrigerate overnight before serving.
