Classification of Cookies

Cookies are broadly classified according to how they are formed, including at least these categories:

Bar cookies consist of batter or other ingredients that are poured or pressed into a pan (sometimes in multiple layers), and cut into cookie-sized pieces after baking. In British English, bar cookies are known as "tray bakes". Examples include brownies, fruit squares, and bars such as date squares.
Drop cookies are made from a relatively soft dough that is dropped by spoonfuls onto the baking sheet. During baking, the mounds of dough spread and flatten. Chocolate chip cookies (Toll House cookies), oatmeal (or oatmeal raisin) cookies and rock cakes are popular examples of drop cookies.
Filled cookies are made from a rolled cookie dough filled with a fruit or confectionery filling before baking. Hamantash are a filled cookie.
Molded cookies are also made from a stiffer dough that is molded into balls or cookie shapes by hand before baking. Snickerdoodles and peanut butter cookies are examples of molded cookies. Some cookies, such as hermits or biscotti, are molded into large flattened loaves that are later cut into smaller cookies.
No-bake cookies are made by mixing a filler, such as cereal or nuts, into a melted confectionery binder, shaping into cookies or bars, and allowing to cool or harden. Oatmeal clusters, Rice Krispies Treats and Rum balls are all no-bake cookies.
Pressed cookies are made from a soft dough that is extruded from a cookie press into various decorative shapes before baking. Spritzgebäck are an example of a pressed cookie.
Refrigerator cookies (also known as icebox cookies) are made from a stiff dough that is refrigerated to become even stiffer. The dough is typically shaped into cylinders which are sliced into round cookies before baking. Pinwheel cookies are representative.
Rolled cookies are made from a stiffer dough that is rolled out and cut into shapes with a cookie cutter. Gingerbread men are an example.
Sandwich cookies are rolled or pressed cookies that are assembled as a sandwich with a sweet filling. Fillings include marshmallow, jam, and icing. The Oreo cookie, made of two chocolate cookies with a vanilla icing filling, is an example.
