Chewy Chocolate Chip Cookies

When we lived in California my cookies would always puff up like tiny cakes, every time. Then my husband seen an episode of Good Eats on the food network about chocolate chip cookies and the different ways to make them to get different results. Of course we didn't need the "puffy" cookie recipe because I was mastering that just fine. Maybe that was due to the altitude? This recipe actually works, the cookies come out chewy and definitely not cake like.
