Bake Cookies Day is celebrated on December 18, 2017. Cookies are most commonly baked until crisp or just long enough that they remain soft, but some kinds of cookies are not baked at all. Cookies are made in a wide variety of styles, using an array of ingredients including sugars, spices, chocolate, butter, peanut butter, nuts, or dried fruits. The softness of the cookie may depend on how long it is baked.
In the United States and Canada a cookie is a small, flat, baked treat, usually containing flour, eggs, sugar, and either butter or cooking oil, and often including ingredients such as raisins, oats, or chocolate chips. Cookies came to America in the early English settlement (the 17th century), although the name "koekje" arrived with the Dutch. This became Anglicized to "cookie" or cooky.
