It makes a very rich, truly decadent chocolate cheesecake. A chocolate wafer is a crisp chocolate cookie about three inches in diameter and an eigth of an inch thick. If you can't find them, you can substitute any kind of dry crunchy chocolate-flavored cookie. You can make the crust and filling in a food processor if you have one. It makes it a lot easier.
