1 Cup (225g) Unsalted Butter 450g Dark Brown Sugar 2 Eggs 1 Tablespoon Vanilla 420g Flour 6g Baking Soda 12g Salt 1 Bag Chocolate Chips

Preheat over to 350*F
Cream together cold (directly from refrigerator) butter and sugar.
Add in eggs and vanilla, cream lightly (do not overmix, froth is bad). The goal is to mix the ingredients, not whip them together.
In separate bowl, whisk together flour, salt, and baking soda.
Add half of the flour mixture into the creamed mixture, combine.
Fold in other half of flour mixture, or mix lightly. Do not overmix, overmixed cookies are tough and gross.
Fold in chocolate chips.
Bake ~18 minutes.
