I found this recipe last year and it’s been my favorite ever since! My friend Claire and I hang out a lot and we make these cookies. I’ve also made them with my friend Jaclyn. Not only do they taste amazing, they’re fun to make. CHEMISTRY INFORMATION: The unmixed batter, the batter after the chocolate chips are added, and the finished cookies are all heterogeneous mixtures. The butter warming up after it is taken out of the refrigerator, and the dough being formed into balls are both physical changes. The puffing up of the cookies and the change in color on the bottom of the cookies as they bake both indicate that chemical changes are taking place.
