Chocolate Cheesecake Supreme

Actually this is for my father's birthday, but he told me that he is on diet so he insist to obey the diet rules and choose not to eat that. So, as I know that he is man with honor, I appreciate that.
Furthermore, my mother had the honor to eat that cheesecake...adn on the first bite she said...WHAT IS THIS??IT IS REALLY TASTEFULL...I SWEAR THE TASTE IS UNFORGETABLE....
