Line muffin tin with paper liners. Preheat the oven to 350 degrees.
Beat together the softened cream cheese, eggs, sugar, melted chocolate, whipping cream and vanilla until creamy and smooth, about 1-2 minutes. Do not whip too much air into the mixture.
Scoop about 1 ½ tablespoon of cookie crumb mixture into each cup and use a small glass or your fingers to pack it down slightly.
Scoop about 2 tablespoon of the cream cheese filling over the cookie crust and smooth the tops.
Bake for about 18-22 minutes or until the middles are mostly set. Cool in the pan for 15 minutes and then transfer the cheesecakes to the refrigerator to chill for 1-2 hours.
Once completely chilled and ready to serve, top with a dollop of chocolate whipped cream or pipe a swirl of whipped cream.
