These chocolate chip cookies are everything that we want: crisp on the edges, soft and chewy everywhere else, with a hint of salt and just enough warm, melty chocolate. They are great just moments from the oven, but the cookies are even chewier, with a more pronounced butterscotch flavor, after the dough sits overnight in the fridge (not the freezer). You add just under a cup of chocolate chips, but you can also customize each cookie by adding more chips, walnuts (YES. Or no) to each cookie, to please everyone. Which is exactly what these cookies will do.
