Wafer cookie

A wafer is a crisp, often sweet, very thin, flat, light and dry biscuit, often used to decorate ice cream, and also used as a garnish on some sweet dishes. 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. Some chocolate bars, such as Kitkat and Coffee Crisp, are wafers with chocolate in and around them.
