Preparation

Step 1: Prepare the Brownie Base

1. Preheat your oven to 350°F (175°C).
2. Line a 9-inch springform pan with parchment paper or grease it lightly to prevent sticking.
3. In a mixing bowl, combine melted butter and granulated sugar until smooth.
4. Whisk in the eggs and vanilla extract until fully incorporated.
5. Add the flour, cocoa powder, and salt, mixing until a smooth batter forms.
6. Pour the brownie batter into the prepared pan and spread it evenly.
7. Bake for 20-25 minutes, or until the edges are set and a toothpick inserted in the center comes out with a few moist crumbs.
8. Let the brownie base cool completely while you prepare the cheesecake layer.

Step 2: Make the Coffee Cheesecake Layer

1. Lower the oven temperature to 325°F (160°C).
2. In a large bowl, beat the softened cream cheese and sugar together until creamy and lump-free.
3. Gradually add the cooled brewed coffee, sour cream, and vanilla extract, mixing thoroughly.
4. Add the eggs one at a time, ensuring each is fully incorporated before adding the next.
5. Sprinkle in the flour and mix just until combined—avoid overmixing to maintain a smooth texture.
6. Pour the cheesecake mixture over the cooled brownie base in the springform pan, smoothing the top with a spatula.

Step 3: Bake the Cheesecake

1. Place the springform pan in the oven and bake for 50-60 minutes. The cheesecake should be set but slightly jiggly in the center when gently shaken.
2. Turn off the oven, crack the door open slightly, and let the cheesecake cool inside the oven for about an hour. This helps prevent cracks on the surface.
3. Once cooled, transfer the cheesecake to the refrigerator and chill for at least 4 hours or overnight for best results.

Step 4: Add the Coffee Ganache (Optional)

1. In a small saucepan, heat the heavy cream and brewed coffee over low heat until warm (do not boil).
2. Pour the warm mixture over the dark chocolate chips in a bowl. Let sit for a minute, then stir until smooth and glossy.
3. Spread the ganache evenly over the chilled cheesecake, allowing it to drizzle slightly over the edges if desired.

Step 5: Decorate & Serve

1. Before serving, top the cheesecake with whipped cream swirls, coffee beans, or chocolate shavings for an elegant finish.
2. Slice into even portions and serve cold.
