Preheat oven to 375 degrees. In a large bowl, thrash butter and sugars until uniform. Beat in eggs and vanilla. Add flour and baking soda; whip until smooth. Toss in chocolate chunks and nuts.
To avoid the chocolate chip cookie cooked under a steam roller look, refrigerate the cookie dough for a couple of hours before baking. Throw batter by tablespoons full onto an ungreased baking sheet aim so that the cookies land 2 inches apart.
Bake until golden, about 10-12 minutes. Using a spatula, pry the cookies loose from the baking sheet, and allow them to vent on wire racks.
