Preheat the oven to 325°F.
In a medium bowl, combine chocolate cookie crumbs and melted butter. Press the mixture firmly into the bottom of a 9-inch springform pan to form the crust.
Bake for 10 minutes, then remove from the oven and let cool.
In a large mixing bowl, beat the softened cream cheese until smooth.
Gradually add the granulated sugar and vanilla extract, mixing until well combined.
Add the eggs one at a time, mixing on low speed until just incorporated.
Stir in the sour cream and melted dark chocolate until smooth.
Pour the cheesecake batter over the cooled crust in the springform pan.
Bake for 50-60 minutes, or until the center is set but slightly jiggly.
Turn off the oven and leave the cheesecake inside for an additional hour to cool gradually.
Remove from the oven and let cool to room temperature, then refrigerate for at least 4 hours or overnight.
Once chilled, spread the cherry pie filling evenly over the top of the cheesecake.
Slice and serve chilled.
