Which cookie is the official state cookie of Massachusetts?

The official state cookie of Massachusetts is the chocolate chip cookie.

Massachusetts designated the chocolate chip cookie as its official state cookie in 1997. The choice reflects the cookie's connection to Ruth Graves Wakefield, who created the famous Toll House cookie while running the Toll House Inn in Whitman, Massachusetts, with her husband, Kenneth, during the 1930s.

Wakefield's recipe was first published in 1938 in Toll House Tried and True Recipes under the name Toll House Chocolate Crunch Cookies. The popular story says she accidentally substituted chopped chocolate for nuts, but historians note that the circumstances are disputed and that Wakefield may have developed the recipe deliberately. The cookie later became nationally famous through Nestlé's chocolate and recipe promotion.

Chocolate chip cookies are drop cookies: portions of dough are placed on a baking sheet rather than rolled and cut into shapes. Recipes commonly combine flour, butter or shortening, white and brown sugar, eggs, vanilla, and a leavener such as baking soda. Brown sugar generally makes the texture chewier, while white sugar promotes crispness. Massachusetts's official designation recognizes the cookie's local history, not its exclusive origin.
