Step 1: Make the Crust

1. Preheat the oven to 350°F (175°C).
2. In a bowl, mix chocolate cookie crumbs, sugar, and melted butter.
3. Press the mixture firmly into the bottom of a 9-inch springform pan.
4. Bake for 8–10 minutes, then let cool completely.

Step 2: Make the Cheesecake Filling

1. In a large bowl, beat the cream cheese and sugar until smooth and creamy.
2. Add eggs one at a time, beating well after each addition.
3. Mix in sour cream, flour, and vanilla extract until fully combined.
4. Stir in the melted chocolate until evenly incorporated.

Step 3: Bake the Cheesecake

1. Pour the filling over the cooled crust.
2. Wrap the springform pan in foil and place it in a larger roasting pan. Fill the roasting pan with 1 inch of hot water (water bath).
3. Bake at 325°F (163°C) for 60–70 minutes, or until the edges are set and the center jiggles slightly.
4. Turn off the oven, crack the door, and let the cheesecake cool for 1 hour.
5. Refrigerate for at least 4 hours or overnight.

Step 4: Make the Chocolate Ganache

1. Heat chocolate chips and heavy cream in the microwave in 30-second intervals, stirring until smooth.
2. Let the ganache cool slightly before using.

Step 5: Assemble the Cheesecake

1. Spread the cherry pie filling evenly over the chilled cheesecake. Add fresh cherries if desired.
2. Drizzle the chocolate ganache on top, allowing it to drip down the sides.

Step 6: Decorate and Serve

1. Garnish with whipped cream, fresh cherries, and chocolate shavings.
2. Chill for an additional hour to set before slicing.
