1. Prepare the Crust

1. Preheat your oven to 325°F (163°C). Grease a 9-inch springform pan and line the bottom with parchment paper.
2. In a medium bowl, combine the chocolate cookie crumbs, melted butter, and granulated sugar. Mix until the crumbs are evenly moistened.
3. Press the mixture firmly into the bottom of the prepared springform pan. Use the bottom of a glass or measuring cup to create an even layer.
4. Bake the crust for 8–10 minutes. Remove from the oven and set aside to cool.

2. Make the Cheesecake Filling

1. In a large mixing bowl, beat the softened cream cheese and sugar together with an electric mixer until smooth and creamy, about 2–3 minutes.
2. Add the vanilla extract and mix until incorporated.
3. Beat in the eggs one at a time, ensuring each is fully mixed before adding the next.
4. Stir in the sour cream, followed by the melted chocolate, mixing just until combined. Avoid overmixing to prevent cracks in the cheesecake.

3. Assemble and Bake

1. Pour the cheesecake filling over the cooled crust, spreading it into an even layer.
2. Place the springform pan on a baking sheet and bake for 60–70 minutes, or until the edges are set but the center still jiggles slightly.
3. Turn off the oven and leave the cheesecake inside with the door slightly ajar for 1 hour. This gradual cooling helps prevent cracks.

4. Cool and Chill

1. Remove the cheesecake from the oven and run a knife around the edge of the pan to loosen it. Let it cool completely at room temperature.
2. Cover the pan with plastic wrap or aluminum foil and refrigerate for at least 6 hours or overnight to fully set.

5. Add the Cherry Topping

1. Once the cheesecake is chilled, spread the cherry pie filling evenly over the top.

6. Whip the Cream

1. In a chilled mixing bowl, beat the heavy cream and powdered sugar with an electric mixer until stiff peaks form.
2. Transfer the whipped cream to a piping bag fitted with a star tip and pipe rosettes around the edges of the cheesecake.

7. Garnish and Serve

1. Sprinkle the cheesecake with chocolate shavings or curls for a finishing touch.
2. Slice with a warm, sharp knife for clean cuts. Serve chilled and enjoy!
