Ingredients:
- 1 ½ cups finely crushed Gingersnap Cookies (or Digestive Biscuits)
- ¼ cup Granulated Sugar (for crust)
- 6 tablespoons Unsalted Butter, melted (for crust)
- 3 oz High-Quality Dark Chocolate (70% cocoa), finely chopped
- 2 tablespoons Strong Brewed Espresso (cooled, for swirl)
- 4 blocks (900g) full-fat Cream Cheese, room temperature
- 1 ½ cups Granulated Sugar (for filling)
- 4 Large Eggs, room temperature
- ½ cup full fat Sour Cream, room temperature
- 1 teaspoon Vanilla Extract
- 2 teaspoons Instant Espresso Powder
- ¼ teaspoon Salt
Instructions:
- Preheat oven to 325°F (160°C). Wrap the exterior of a 9-inch springform pan securely in two layers of heavy-duty aluminum foil to waterproof it.
- Make the Crust: Combine crushed cookies, ¼ cup sugar, and melted butter. Press firmly and evenly into the bottom of the prepared pan. Bake for 10 minutes; cool completely.
- Prepare the Coffee Swirl Mixture: Gently melt the dark chocolate with 1 tablespoon of the cooled espresso until smooth. Set aside to cool slightly.
- Mix the Cheesecake Base: Beat the room-temperature cream cheese until completely smooth. Gradually beat in the 1 ½ cups of sugar until fluffy. Beat in sour cream, vanilla, salt, and the 2 teaspoons of espresso powder.
- Incorporate Eggs: Beat in the eggs one at a time, mixing just until each is incorporated. Avoid over-mixing.
- Assemble & Swirl: Pour two-thirds of the cheesecake batter over the cooled crust. Drizzle the chocolate-espresso mixture randomly over this layer. Pour the remaining plain batter on top. Gently drizzle the final tablespoon of plain espresso over the top layer. Use a butter knife to gently swirl the colours together 1-2 times.
- The Water Bath (Bain-Marie): Place the foil-wrapped springform pan inside a large roasting pan. Carefully pour boiling water into the roasting pan until the water level comes halfway up the sides of the springform pan.
- Bake for 65–75 minutes. The edges should look set, but the very centre should still have a slight, gentle wobble.
- Cool Down: Turn the oven off. Crack the oven door open slightly (use a wooden spoon to prop it). Leave the cheesecake inside the cooling oven for 1 hour.
- Final Chill: Remove the cheesecake from the water bath and foil, cool to room temperature on a wire rack, then chill, covered, in the refrigerator for at least 6 hours before slicing and serving.
