This is Alton Browns Chewy Recipe from the Good Eats episode : Chips for Sister Marsha (Youtube link)& Part Two

also featured in the episode

The Thin (Crispy) Cookie

The Puffy Cookie

I use the chewy recipe and add the variation of using browned butter instead of just melted butter (gives the cookies a toffee kind of flavor). To make browned butter melt the butter in a saucepan, keep the heat on until the butter starts to turn a hazelnut color. Turn off the heat and place the saucepan on a wet cloth (or a bowl of water) just to stop the butter from overcooking and burning.

I like to add things like walnuts and cranberries and nix the chocolate chips for a change.
