Cookies have a wonderful aroma because molecules disperse through the air as they bake. The process of baking turns the moisture (water) in cookie dough into steam. This steam rises with the heat of the oven, escaping through vents and dispersing through the kitchen and into the nearby environment. The steam carries minute molecules of all the other ingredients in the cookies, such as the butter, sugar, vanilla and flour, all of which combine to produce the delicious cookie smell.
