Method
- Preheat your oven to 160°C (320°F). Grease a 23cm (9-inch) springform pan thoroughly with butter and line the base with a circle of parchment paper. Grease the parchment. Wrap the outside of the springform pan tightly with two layers of heavy-duty aluminium foil, bringing the foil as high as possible on all sides. Place a large roasting pan on the lower oven rack. Boil a full kettle of water and set aside for the water bath.
- Combine the cooled espresso and coffee liqueur in a shallow bowl. Working quickly one at a time, dip each ladyfinger into the espresso mixture for exactly one second per side — moistened but not saturated. Break the dipped ladyfingers roughly and press into the prepared springform pan base in an even layer. Drizzle the melted butter and tablespoon of sugar over the pressed layer. Press down firmly with the back of a flat glass to compact into a cohesive crust. Refrigerate for 15 minutes while making the filling.
- Beat the room temperature mascarpone and cream cheese together on medium-low speed for 2 minutes until completely smooth and lump-free. Add both sugars and beat on medium-low for 2 more minutes. Add the eggs and egg yolks one at a time, beating on low speed just until incorporated after each addition — do not beat vigorously. Add the vanilla extract, fine sea salt, cooled espresso, coffee liqueur, and cornstarch. Beat on low for 30 seconds maximum. Gently fold in the heavy cream with a wide rubber spatula until just combined.
- Remove the springform pan from the refrigerator. Pour the cheesecake filling over the chilled ladyfinger crust in a slow steady stream from the center, letting it spread naturally. Tap the pan gently on the counter 3–4 times to release air bubbles. Place the foil-wrapped springform pan inside the roasting pan on the lower oven rack. Pour boiled water into the roasting pan until it reaches halfway up the sides of the springform pan. Bake at 160°C (320°F) for 60–70 minutes until the edges are set with a gentle slow wobble at the center. Tent loosely with foil if the surface begins to brown.
- Turn off the oven, prop the door open with a wooden spoon, and leave the cheesecake in the oven for 1 hour. Remove, run a thin knife carefully around the inside edge of the pan. Cool completely at room temperature for another hour. Cover loosely and refrigerate for a minimum of 6 hours — overnight is ideal and produces a significantly better-set, more flavourful result.
- Beat the room temperature mascarpone until smooth. In a separate bowl, whip the very cold heavy cream with the sifted powdered sugar, vanilla, and coffee liqueur if using, until firm peaks form. Gently fold the whipped cream into the mascarpone with a wide spatula using slow sweeping motions until completely combined, thick, smooth, and holding its shape. Stop folding the moment the mixture is uniform.
- Release the springform pan sides and transfer the chilled cheesecake to a serving plate or cake stand. Spread or pipe the mascarpone cream topping evenly across the entire top surface creating swirls or a smooth finish. Using a fine mesh sieve, dust a generous even layer of Dutch-processed cocoa powder over the entire top within 30 minutes of serving. Add dark chocolate shavings or whole ladyfinger decorations if desired. Slice with a sharp knife dipped in hot water and wiped dry between each cut.
Notes
Pro Tips: All dairy must be at room temperature — mascarpone, cream cheese and eggs need a minimum of 1 hour out of the refrigerator before starting, 2 hours is better — cold mascarpone becomes grainy and lumpy when beaten and cannot be corrected. Dip each ladyfinger for one second only per side — any longer produces a saturated, structureless, soggy crust. Never beat eggs vigorously after they are added — beat each egg on the lowest speed just until incorporated to avoid incorporating air that causes cracking. The water bath is not optional — it is what produces the smooth uncracked surface that makes this cheesecake stunning. Cool in the oven with the door propped open for 1 hour before removing — rapid temperature change is the primary cause of cracking. Chill overnight for the best set, cleanest slices and deepest espresso flavour development. Dust the cocoa within 30 minutes of serving — cocoa absorbs moisture from the cream topping over time and becomes wet and dull if added too far in advance.
