In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
In a large bowl, whisk together the brown sugar, melted butter, and granulated sugar. Whisk in the eggs and vanilla extract until combined.
Add the flour mixture to the butter mixture. Use a rubber spatula to stir just until the ingredients are combined (and you don’t see any dry pockets of flour).
Fold in the chocolate chips.
Cover the bowl and chill for 15 minutes while you preheat the oven and prepare the baking sheets. Preheat oven to 325°F. Line two rimmed baking sheets with parchment paper. Using a 1 ½-tablespoon cookie dough scoop, drop the dough in round balls apart 2 inches apart on the prepared baking sheets. If you like, you can press a few additional chocolate chips into the top of each dough ball for a bakery-style appearance. For really thick cookies, you can pop the trays back in the fridge or freezer for about 15 minutes to chill again before baking (this isn't necessary, just a bonus).
Bake the cookies until the edges are set and beginning to brown, but the centers are still soft and puffy, about 15-16 minutes. The cookies will continue to firm up as they cool, so be sure that you don’t overbake them or they’ll be tough and crunchy. Let the cookies cool on the baking sheets for about 5 minutes, and then transfer to a wire cooling rack to cool completely before storing.
