Instructions
Prepare the Brownie Crust
- Preheat the oven to 350°F (180°C). Line a 9-inch springform pan with parchment paper and wrap the outside with aluminum foil.
- Melt the bittersweet chocolate and butter together in the microwave, stirring every 30 seconds until smooth. Cool slightly.
- Beat the sugar, eggs, and vanilla until pale and frothy.
- Slowly pour in the melted chocolate mixture while mixing.
- Fold in the flour, cocoa powder, and salt until just combined.
- Spread the batter evenly into the prepared pan.
- Bake for 25–30 minutes or until a toothpick comes out mostly clean.
- Cool completely before adding the cheesecake layer.
Prepare the Cheesecake Filling
- Lower the oven temperature to 325°F (165°C).
- Place a pan of warm water on the bottom oven rack to create steam.

- Mix in the melted chocolate, vanilla, cocoa powder, and salt.
- Blend in the sour cream.
- Add the eggs one at a time, mixing gently after each addition.
- Pour the filling over the cooled brownie crust.
- Bake the Cosmic Brownie Cheesecake for 60–70 minutes, until the edges are set and the center still has a slight jiggle.
- Turn off the oven, crack the door open, and allow the cheesecake to cool inside for one hour.
- Cool at room temperature for another hour before refrigerating overnight.
Make the Chocolate Ganache
- Place the chocolate chips into a bowl.
- Heat the heavy cream until steaming but not boiling.
- Pour over the chocolate.
- Let stand for one minute before whisking until smooth.
- Chill for about one hour until slightly thickened.

Can I make Cosmic Brownie Cheesecake ahead of time?
Yes. It actually tastes even better after chilling overnight.
Can I freeze this cheesecake?

Yes, but the finished cheesecake will be sweeter.

The steam bath recommended in this recipe helps create a creamy texture and minimizes cracking without placing the cheesecake directly in water.
