These cookies are rooted classic Toll House flavor, but browning the butter amps up the toasty notes and is key to developing the balance of crisp edges, while a high ratio of brown sugar to white sugar ensures chewy chocolate chip cookie centers. The amount of flour and the quality of the pure vanilla extract is important here. We highly recommend weighing your flour with a scale; if you don't have one, use a spoon to scoop the flour into a measuring cup until overflowing, and a straight edge (such as the back of a butter knife) to level it off.
You can store the cookie dough in an air-tight containter in the freezer for a few months—the earlier the raw dough is used, the better. To store already baked cookies in the refridgerator, place them in an air-tight container or a sealable plastic bag and store them in the fridge for up to two weeks. Unrefridgerated cookies will stay fresh for two to three days. You can also store baked cookies in the freezer for up to a year in an air-tight container.
