Cheesecake is a sweet dessert consisting of one or more
layers. The main, and thickest, layer consists of a mixture of a soft,
fresh cheese
(typically cottage cheese, cream cheese or ricotta), eggs, and
sugar. If there is a bottom layer, it most often consists of a crust or
base made from crushed cookies (or digestive biscuits), graham
crackers, pastry, or sometimes sponge cake.
