This is honestly the best double chocolate cheesecake you will ever have. It is rich, creamy and decadent. I'm providing directions for baking in a conventional oven, but check the notes for how I did it in the pressure cooker if you feel like giving that a shot. Use your favorite chocolate crumb crust. This recipe makes 1 6" x 3" cake and will serve 6-8 people. Feel free to double it to serve 16. In that case, you'll need a 9" x 3" springform pan for baking. No hard math for scaling--just double everything and it'll work out fine.
