Main Difference
The main difference between Biscuit and Wafer is that the Biscuit is a small sweet baked product and Wafer is a thin type of biscuit
Biscuit
Biscuit is a term used for a variety of primarily flour-based baked food products. The term is applied to two distinct products. This article covers the type of biscuit found in Africa, Asia and Europe, which is typically hard, flat and unleavened. In North America, a biscuit is typically a soft, leavened quick bread, and is covered in the article Biscuit (bread).
Wafer
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 Kit Kat and Coffee Crisp, are wafers with chocolate in and around them.
