Prep Time 15 minutes
Cook Time 13 minutes
Total Time 28 minutes
Servings: 20 cookies
Ingredients Method Notes

Ingredients
  

  • 2 cups all-purpose flour
  • 3/4 cup Dutch-process cocoa powder
  • 1 tsp baking soda
  • 1 tsp fine sea salt
  • 1 cup (2 sticks) unsalted butter, room temperature
  • 1 cup granulated sugar
  • 3/4 cup packed light brown sugar
  • 2 large eggs, room temperature
  • 2 tsp vanilla extract
  • 8 oz semi-sweet chocolate, roughly chopped
  • Flaky sea salt, for finishing

Method
 

  1. Whisk together the flour, cocoa powder, baking soda, and salt in a large bowl until no streaks of cocoa remain.
  2. Beat the butter, granulated sugar, and brown sugar on medium-high for 3 to 4 minutes until light and fluffy.
  3. Add the eggs one at a time, beating 30 seconds after each, then add the vanilla and beat 30 more seconds.
  4. Add the dry ingredients to the butter mixture and mix on low until just combined, then fold in the chopped chocolate by hand.
  5. Cover the dough and refrigerate for at least 30 minutes. Preheat oven to 375°F (190°C) and line 2 baking sheets with parchment.
  6. Scoop dough into 3 tbsp balls spaced 3 inches apart. Bake on the center rack for 11 to 13 minutes until edges are set. Sprinkle with flaky sea salt immediately and let sit on the pan for 5 minutes before transferring to a wire rack.

Notes

The chilling time is not included in the prep or cook time above, so plan for at least 30 extra minutes before baking. The cookies come out looking underdone at 11 to 13 minutes and that's intentional; they set up as they cool on the pan. If you're baking a second sheet, keep that dough in the fridge while the first batch bakes.
