I've heard this debate flare up on a few different radio stations, nobody seems to know the exact conclusion of what the real truth is behind Cheese Cake. So allow me to pose this question with some quick variables to consider: Pie a baked food having a filling of fruit, meat, pudding, etc., prepared in a pastry-lined pan or dish and often topped with a pastry crust: apple pie; meat pie. a layer cake with a filling of custard, cream jelly, or the like: chocolate cream pie. Cake a sweet, baked, breadlike food, made with or without shortening, and usually containing flour, sugar, baking powder or soda, eggs, and liquid flavoring. a flat, thin mass of bread, esp. unleavened bread. So knowing that.... is Cheesecake... a cake or a Pie?
