01 - Preheat oven to 325°F. Grease a 9-inch springform pan and line the bottom with parchment paper. Combine cookie crumbs, melted butter, and sugar in a bowl. Press firmly into the bottom of the prepared pan and bake for 10 minutes. Set aside to cool.
02 - Beat cream cheese and sugar in a large bowl until smooth and creamy. Add eggs one at a time, mixing well after each addition. Stir in sour cream, vanilla extract, peppermint extract, and salt until just combined.
03 - Pour filling over the cooled crust and smooth the top. Bake for 45 to 50 minutes, until edges are set and center is slightly wobbly. Turn off oven, crack door, and let cheesecake cool inside for 1 hour.
04 - Run a thin knife around the edge of the cake, then cool completely at room temperature. Refrigerate for at least 3 hours or preferably overnight to set.
05 - Whip heavy cream with powdered sugar and peppermint extract until stiff peaks form. Spread or pipe over the chilled cheesecake.
06 - Sprinkle crushed peppermint candies on top just before serving.
