Cookies, while not a common ingredient in cocktails, can be used to add a unique flavor and texture to drinks. When used in cocktails, cookies are often crumbled and used as a rim garnish or blended into the drink itself. For example, a "Cookies and Cream" cocktail might feature a creamy base spirit like Bailey's Irish Cream, vodka, or rum, blended with chocolate cookies for a sweet and indulgent treat.
