Most of the time I completely follow the recipe, but every now in then I stumble upon a trick that makes the cookies even tastier. Cinnamon seems to add great flavor to just about any cookie recipe, even chocolate. So I put a little bit in almost all my cookie recipes. I've also discovered that if you put the chocolate chips on the cookies after the batter has backed, they will be much more melted and not dried up. Anyway, that's my two cents!
