Snickerdoodle

A snickerdoodle is a type of cookie made with flour, fat, sugar, and salt, and rolled in cinnamon sugar. Other spice-sugar mixes may also be used, such as cardamom sugar or a mixture of cardamom, cinnamon, and allspice. Eggs may also sometimes be used as an ingredient, with cream of tartar and baking soda added to leaven the dough. Snickerdoodles are characterized by a cracked surface and can be either crisp or soft depending on the ingredients used.

While snickerdoodles may appear similar to "sugar cookies", traditional sugar cookies are often rolled in white sugar whereas snickerdoodles are rolled in a mixture of white sugar and cinnamon. Cream of tartar is added for its signature effect on texture and taste as another main difference. Sugar cookies usually contain only baking soda and/or baking powder, not tartar.
