In
gastronomy, a
wafer is a crisp, often sweet, very thin, flat, and dry
biscuit, often used to decorate
ice cream. Wafers can also be made into
cookies with cream flavoring sandwiched between them. They frequently have a
waffle surface pattern but may also be patterned with insignia of the food's manufacturer or may be patternless. Many chocolate bars, such as
Kit Kat and
Coffee Crisp, have wafers in them.
