bake until edges are set and centers look slightly underbaked 9 to 11 minutes
cool on the baking sheet 5 minutes then transfer to a rack to cool completely.
Notes
1. For extra thick cookies chill the dough 1 to 24 hours; Swap semisweet chips for dark chocolate chunks or mini chips; Use natural peanut butter only if well stirred and expect a slightly crumblier cookie; Underbake slightly for a softer center
