Preheat oven to 350ºF. Line baking sheets with parchment paper.

In a medium bowl, combine the flour, baking soda, and salt.

In the bowl of an electric mixer, beat the butter, granulated sugar, and brown sugar until creamy, about 2 minutes. Scrape down the sides and bottom of the mixing bowl. Add the vanilla and eggs and beat until combined, scraping the bowl down as needed. Gradually beat in the flour mixture. Stir in the chocolate chips.

If time permits, wrap dough in plastic wrap and refrigerate for at least 24 hours but no more than 72 hours. This allows the dough to 'marinate' and makes the cookies thicker, chewier, and more flavorful. Let dough sit at room temperature just until it is soft enough to scoop.

Divide the dough into 3-tablespoon sized balls using a large cookie scoop and drop onto prepared baking sheets.

Bake for 11-13 minutes, or until golden brown. Cool for 5 minutes before removing to wire racks to cool completely.

Although I prefer cookies fresh from the oven, these can be stored in an airtight container for up to 3 days. See post for storage tips.
