Instructions:
- Pulse the chocolate cookies in a food processor (or crush in a zip-top bag with a rolling pin) until finely ground.

- Press the mixture firmly into the bottom of the springform pan.
- Chill the crust for at least 30 minutes (preferably an hour).
- Preheat oven to 325°F (160°C).
- Wrap the bottom of the springform pan tightly in aluminum foil (to prevent leaks if using a water bath).
- Beat cream cheese and mascarpone cheese until smooth and creamy.
- Gradually add sugar and cocoa powder, mixing until well combined.
- Stir in vanilla extract and salt.
- Beat in eggs one at a time, mixing until just combined (avoid over-mixing).
- Stir in heavy cream.
- Gently fold in melted and slightly cooled chocolate.
- Pour the filling over the chilled crust.
- Bake for 60-70 minutes, or until the edges are set but the center still has a slight jiggle.
- Turn off the oven and let the cheesecake cool in the oven with the door ajar for 1 hour.
- Remove from oven and let cool completely at room temperature for another hour.
- Cover and refrigerate for at least 4 hours, or preferably overnight.
- Heat heavy cream in a double boiler (or microwave) until simmering.
- Pour the hot cream over the chopped chocolate.
- Let sit for 1 minute, then stir until smooth and glossy.
- Remove the sides of the springform pan.
- Pour the chocolate ganache over the top of the cheesecake.
- Smooth the ganache evenly.
- Chill for another 30 minutes to allow the ganache to set slightly.
- Slice and serve!
