Combine the cookie crumbs and melted butter in a medium bowl, stirring until the mixture resembles wet sand.

Press the crumb mixture firmly into the bottom and slightly up the sides of a 9-inch springform pan, then place it in the freezer to firm up while you prepare the filling.

In a large bowl, beat the softened cream cheese and granulated sugar with an electric mixer on medium-high speed until the texture is completely smooth and free of lumps.

Pour the melted chocolate and vanilla extract into the cream cheese mixture, beating on low speed until fully incorporated and uniform in color.

In a separate chilled bowl, whip the heavy cream on high speed until stiff peaks form, ensuring you don’t over-whip it into butter.

Gently fold the whipped cream into the chocolate cream cheese mixture using a rubber spatula, working in two batches to keep the filling light and airy.

Pour the filling over the prepared crust, smoothing the top with your spatula to create an even surface.

Cover the pan tightly with plastic wrap and refrigerate for at least 6 hours, or until the filling is firm to the touch.

Release the sides of the springform pan carefully before slicing with a hot, clean knife to achieve sharp, clean edges.
