Preheat the oven to 325°F (165°C). Grease a 9-inch springform pan.
In a bowl, combine graham cracker crumbs, melted butter, and sugar. Press the mixture into the bottom of the prepared pan to form a crust.
In a large mixing bowl, beat cream cheese and 1 cup of sugar until smooth. Add eggs one at a time, beating well after each addition.
Stir in vanilla extract and mascarpone cheese until blended. Pour half of the batter over the crust.
Mix espresso and coffee liqueur together. Dip ladyfinger biscuits briefly and layer over the cheesecake filling. Pour remaining batter over the biscuits.
Bake in the preheated oven for about 60 minutes, until the center is set and edges are lightly browned.
Allow to cool in the pan on a wire rack. Refrigerate for at least 4 hours or overnight.
Before serving, top with whipped cream, a dusting of cocoa powder, and chocolate shavings.
