These cookies are our go-to dessert for most celebrations, especially holidays and birthdays. Everyone is excited when they come out of the oven, and it is impossible to have just one. CHEMISTRY INFORMATION: The cookies after the sugar is added and the unmixed batter are both heterogeneous mixtures. The cookies before we sugar them and the mixed batter are homogeneous mixtures. The dough being molded into shapes and the butter softening at room temperature are physical changes. The smell of the cookies after they are finished cooking is a clue of a chemical change, as well as the cookies raising to twice their original height.
