Method
1. Whisk together flour, baking soda, and salt in a large bowl
2. Place granulated sugar, eggs, and vanilla extract in the bowl of a stand mixer fitted with the whisk attachment
3. Whisk on medium-high speed until mixture is pale brownish-yellow and falls off the whisk in thick ribbons when lifted, about 5 minutes
4. Fit paddle attachment onto mixer. Add brown sugar and cooled brown butter to egg mixture in stand mixer
5. Mix on medium speed to combine, about 15 seconds
6. Add flour mixture and mix on low speed until just barely combined, with some dry flour still remaining, about 15 seconds
7. Add chocolate and mix on low speed until dough comes together, about 15 seconds longer
8. Transfer to an airtight container and refrigerate dough at least overnight and up to 3 days
9. When ready to bake, adjust oven racks to upper- and lower-middle positions and preheat oven to 325°F (160°C)
10. Using a 1-ounce ice cream scoop or a spoon, place scoops of cookie dough onto a nonstick or parchment-lined baking sheet
11. Tear each ball in half to reveal a rougher surface, then stick them back together with the rough sides facing outward
12. Transfer to oven and bake until golden brown around edges but still soft, 13 to 16 minutes, rotating pans back to front and top to bottom halfway through baking
13. Remove baking sheets from oven. While cookies are still hot, sprinkle very lightly with coarse salt and gently press salt down to embed
14. Let cool for 2 minutes, then transfer cookies to a wire rack to cool completely
