Chocolate chip cookies are commonly made with [[white sugar]]; [[brown sugar]]; [[flour]]; [[salt]]; [[Egg (food)|eggs]]; a [[leavening agent]] such as [[baking soda]]; a fat, typically butter or [[shortening]]; [[vanilla extract]]; and [[chocolate]] pieces. Some recipes also include milk or [[nut (fruit)|nuts]] (such as chopped [[walnuts]]) in the dough.

Depending on the ratio of ingredients and mixing and cooking times, some recipes produce a soft, chewy cookie while others will produce a crunchy, crispy cookie.<ref>Levitt, Jonathan. "They're Not As Easy To Make As To Eat", ''[[The Boston Globe]]'', 7 June 2006, C2. Available through [[ProQuest]] eLibrary.</ref> Regardless of ingredients, the procedure for making the cookie is fairly consistent in all recipes: First, the sugars and fat are [[creaming (food)|creamed]], usually with a wooden spoon or [[electric mixer]]. Next, the eggs and vanilla extract are added followed by the flour and leavening agent. Depending on the additional flavoring, its addition to the mix will be determined by the type used: [[peanut butter]] will be added with the wet ingredients while cocoa powder would be added with the dry ingredients. The titular ingredient, chocolate chips, as well as nuts are typically mixed in towards the end of the process to minimize breakage, just before the cookies are scooped and positioned on a [[cookie sheet]]. Most [[cookie dough]] is baked, although some eat the dough as is, or use it as an addition to vanilla [[ice cream]] to make [[chocolate chip cookie dough ice cream]].

The texture of a chocolate chip cookie is largely dependent on its fat composition and the type of fat used. A study done by Kansas State University showed that carbohydrate-based fat substitutes tend to bind more water, leaving less water available to aid in the spread of the cookie while baking and resulting in softer, cakelike cookies with less spread.<ref>{{Cite journal |last1=Armbrister |first1=W.L. |last2=Setser |first2=C.S. |year=1994 |title=Sensory and Physical Properties of Chocolate Chip Cookies Made with Vegetable Shortening or Fat Replacers at 50 and 75% Levels |url=https://www.cerealsgrains.org/publications/cc/backissues/1994/documents/71_344.pdf |journal=Cereal Chemistry |volume=71 |issue=4 |pages=344–351 |access-date=2023-10-02 |archive-date=2023-12-03 |archive-url=https://web.archive.org/web/20231203052828/https://www.cerealsgrains.org/publications/cc/backissues/1994/documents/71_344.pdf |url-status=live }}</ref>

===Marketing===

There are at least three national (U.S./[[North America]]) chains that sell freshly baked chocolate chip cookies in [[shopping mall]]s and standalone retail locations.{{citation needed|date=September 2021}} Several businesses—including [[Doubletree]] hotels—offer freshly baked cookies to their patrons to differentiate themselves from their competition.<ref>{{Citation | author = Nancy Trejos | title = DoubleTree hotels hands out free cookies | newspaper = [[USA Today]] | date = 18 December 2017 | url = https://www.usatoday.com/story/travel/roadwarriorvoices/2017/12/18/doubletree-hotels-expand-cookie-program-and-much-more/960173001/ | access-date = 3 May 2018 | archive-date = 30 March 2019 | archive-url = https://web.archive.org/web/20190330023703/https://www.usatoday.com/story/travel/roadwarriorvoices/2017/12/18/doubletree-hotels-expand-cookie-program-and-much-more/960173001/ | url-status = live }}</ref>

To honor the cookie's creation in the state, on July 9, 1997, Massachusetts designated the chocolate chip cookie as the Official State Cookie, after it was proposed by a third-grade class from [[Somerset, Massachusetts]].<ref>{{cite web | url= http://www.sec.state.ma.us/cis/cismaf/mf1a.htm | title= Massachusetts Facts - State Symbols: Official Cookie | author= William Francis Galvin, Secretary of the Commonwealth of Massachusetts | access-date= 3 May 2018 | archive-date= 12 May 2011 | archive-url= https://web.archive.org/web/20110512231025/http://www.sec.state.ma.us/cis/cismaf/mf1a.htm | url-status= live }}</ref>
