Classic cheesecake is like the traditional cheesecake, with a biscuit base topped with soft, fresh cheese. However, it takes much less time to bake than the traditional cheesecake. The classic cheesecakes are baked with a base made out of ground crackers, butter and sugar. The filling is made up of cream cheese, sugar, lemon juice, flour and eggs. However, the topping is one part where a lot of experimentation is possible. Among the most popular toppings for the classic cheesecake, there is strawberry, raspberry, blackberry, blueberry or boysenberry.
