Preheat oven to 350° F.
In a large mixing bowl, whisk flour, baking soda and salt. In a separate mixing bowl, add butter and sugars, beat together until combined and fluffy. Add eggs and vanilla and mix until combined. Add flour mixture, and mix only until combined. Fold in chocolate chips and walnuts.
Scoop with mini ice cream scoop (roughly one scant tablespoon) into balls, roll in granulated sugar.
Place on greased or lined baking sheets 2-3 inches apart. Gently depress tops to make flat, thick disks. Sprinkle on a bit more sugar, if desired.
Bake at 350° F for 10-12 minutes. Remove to a cooling rack. When cooled, serve piled high into a Styrofoam cup for full “Fair effect” alongside a cold glass of milk.
