Preheat oven to 325°F (163°C). Grease a 9-inch springform pan.
Combine chocolate cookie crumbs and melted butter in a bowl. Press mixture into the bottom of the prepared pan to form a crust.
In a large mixing bowl, beat the cream cheese until smooth. Add the sugar gradually until well combined.
Add eggs, one at a time, beating after each addition. Stir in vanilla extract and melted chocolate.
Pour the cream cheese mixture over the crust and smooth the top with a spatula.
Bake in the preheated oven for about 1 hour, or until the center is set and edges are slightly puffed.
Turn off the oven, leave the cheesecake inside with the door slightly open to cool gradually for 1 hour.
Spread warmed raspberry jam over the cooled cheesecake, and top with fresh raspberries. Refrigerate for at least 3 hours before serving.
