Prepare the crust by combining gingerbread cookies and melted butter.
Preheat the oven to 325°F (160°C).
In a mixing bowl, beat together cream cheese and sugar until smooth.
Add sour cream, vanilla extract, and eggs one at a time, mixing thoroughly.
Mix in flour and optional peppermint extract until just combined.
Pour the filling over the prepared crust and smooth the top.
Bake in the preheated oven for 50-60 minutes, until the edges are set but the center is still slightly jiggly.
Turn off the oven, crack the oven door, and let the cheesecake cool inside for 1 hour.
Chill the cheesecake in the refrigerator for at least 4 hours or overnight before serving.
Garnish with whipped cream, crushed peppermint, or extra gingerbread crumbs if desired.
