Cookie dough refers to a blend of cookie ingredients which has been mixed into a malleable form which has not yet been hardened by heat. The dough is often then separated and the portions baked to individual cookies, or eaten as is.
Cookie dough can be homemade or bought pre-made in packs (frozen logs, buckets, etc.). Desserts containing cookie dough, such as ice cream, candy, and milkshakes are also frequently marketed. Pre-made cookie doughs are usually sold in a few different common flavors including Chocolate Chip, Oatmeal Raisin, Peanut Butter, Sugar, Snickerdoodle, and White Chocolate Macadamia.

Health concerns 
Because of the presence of raw egg, the consumption of uncooked cookie dough increases the possibility of contracting the foodborne illness salmonellosis. The U.S. Food and Drug Administration (FDA) strongly discourages the consumption of all food products containing raw egg because of this threat. Cookie dough designed specifically for eating raw (such as that found in ice cream) is made either without raw egg or with pasteurized eggs and is safe to eat. In June 2009, the FDA issued a recall for Nestlé Cookie Dough for potentially dangerous amounts of E. coli. There have been more than 7,000 cases of E. coli poisoning linked to this cookie dough, but none of the cases were fatal.
In 2010, Nestle decided to switch to heat treated processing for all flour used in producing cookie dough.
