The six basic types of cookies are:
Drop cookies: These are made by dropping spoonfuls of dough onto a baking sheet, like chocolate chip cookies or oatmeal raisin cookies.
Rolled cookies: This type requires rolling out the dough and using a cookie cutter to create shapes, such as sugar cookies.
Refrigerator cookies (or slice-and-bake cookies): The dough is usually shaped into a log, chilled, and then sliced and baked.
Molded cookies: The dough is shaped by hand into specific designs before baking.
Pressed cookies: These are created by pressing dough through a cookie press to form fancy shapes and patterns.
Bar cookies: They're made by spreading the dough in a pan, baking, and then cutting it into bar shapes.
