I like a chocolate chip cookie with chewy innards and a slightly crisp edge, buttery crumbs, complex flavors, and lots of chocolate chips. With those standards, this is the recipe for the best chocolate chip cookies.
In one mixing bowl, whisk together all dry ingredients except the sugars and the flaky salt (cake flour, bread flour, baking soda, baking powder, and coarse salt) until combined.
In a bowl fitted to an electric mixer, cream together the butter and sugar until light and fluffy.
Beat in the eggs one at a time, then beat in the vanilla.
Add the flour in 3-4 batches, stirring well and scraping the sides of the bowl with a rubber spatula between each addition.
Mix in the chocolate chips.
Wrap the dough in airtight wrap (such as plastic wrap) and allow to chill for at least 24 hours (up to 72 hours).
When the dough has chilled, weigh it in grams on a kitchen scale, and divide your total by 20 (that's how many cookies we're making). If there is any remainder, discard it or bake it into a small cookie.
Preheat your oven to 350F.
Divide your dough into 20 even balls and space them out on your cookie sheets. They should be about the size of golf balls. Do not press them flatter; they will spread significantly.
Sprinkle each cookie with a bit of flaky salt. Bake for 15 to 20 minutes.
Allow cookies to cool for about 2 minutes on the baking sheet, then transfer to a cooling rack and cool an additional 10 minutes.
