This is a very rich dessert, it could easily serve 18 people. An old friend of mine used to make this for special occasions, I think she found it in Mr. Food magazine years ago. I like that you don't have to fuss with a springform pan or crushing cookies for the crust. Make sure you use the rolls of cookie dough and not the break and bake variety. The instructions say to refrigerate for 4 hrs before serving but we have eaten it after only cooling it for an hour on the counter and that is a whole new treat in itself.
