Ingredients
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- 1 cup (2 sticks) unsalted butter
- 3/4 cup packed dark brown sugar
- 1/2 cup granulated sugar
- 1 teaspoon Diamond Crystal Kosher Salt
- 1 tablespoon vanilla extract
- 1 large egg
- 1 large egg yolk
- 12 oz chopped bittersweet chocolate (60-70% cacao)
- Flaky sea salt, for sprinkling
Brown the Butter
First, melt the butter in a light-colored skillet over medium heat.
Keep swirling the pan. The butter will foam, then subside, then you’ll see golden-brown specks form at the bottom and it will smell nutty. Pull it off the heat immediately and pour it into a large heatproof bowl.
Build the Cookie Dough Base
To the bowl with the hot brown butter, add both sugars and the salt. Whisk until combined.
Let this mixture cool for ~10 minutes. You don’t want to scramble the eggs.
Use the Whisking Method for Texture
Once cooled slightly, add the egg and egg yolk. Whisk for 30 seconds.
Let the mixture stand for 3 minutes.
Repeat this process two more times: whisk for 30 seconds, then let it stand for 3 minutes. By the end, the mixture will be thick, smooth, and glossy. This helps create the crackly top.
After the final whisk, stir in the vanilla extract.
Finish and Chill the Dough
Add the flour and baking soda to the wet ingredients. Use a rubber spatula to fold until just a few streaks of flour remain.
Add the chopped chocolate and fold until evenly distributed.
Cover the bowl and refrigerate the dough for at least 1 hour, but overnight is better. Chilling the dough prevents the cookies from spreading too much and deepens the flavor.
Bake the Cookies
Preheat your oven to 375F. Line two baking sheets with parchment paper.
Scoop the dough into balls, about 2 tablespoons each. Place them a few inches apart on the baking sheets.
Sprinkle the top of each dough ball with flaky sea salt.
Bake for ~10-12 minutes, until the edges are set and golden brown but the centers are still soft.
Let the cookies cool on the baking sheet for at least 5 minutes before transferring them to a wire rack. They are fragile when hot.
