There are so many layers and textures and chocolate flavors in this amazing cheesecake; it’s difficult to know where to begin. The bottom starts with a mixture of graham cracker crumbs and pecans mixed with butter, sugar and egg whites for a crunchy cookie crust. Next up is a rich and chocolaty brownie layer that is first baked, and then covered with a marvelously rich chocolate and cream cheese filling. And to finish, a fudgy chocolate sauce is spread over the top along with a sprinkling of miniature marshmallows and pecans. This large Mississippi Mud Cheesecake is a feast for the eyes, a treasure for the stomach, and will be the star of any holiday table.
