Ingredients:

  • 1 cup (225g) unsalted butter
  • 3/4 cup (150g) brown sugar (packed)
  • 1/2 cup (100g) granulated sugar
  • 2 large eggs (100g)
  • 2 tsp (10ml) vanilla extract
  • 3/4 cup (75g) Dutch-processed cocoa powder
  • 2 cups (250g) all-purpose flour
  • 1 tsp (5g) baking soda
  • 1/2 tsp (3g) salt
  • 1 1/2 cups (255g) bittersweet chocolate chips
  • 1/2 cup (85g) semi-sweet chocolate chunks
  • flaky sea salt for garnish

Instructions:

  1. Melt butter in a saucepan over medium heat. Stir constantly until it foams and brown bits form at the bottom and it smells nutty. Remove from heat and let cool for 5 minutes.
  2. Whisk the browned butter with brown and granulated sugars until smooth.
  3. Beat in the eggs and vanilla extract until the mixture looks glossy and cohesive.
  4. Sift together the flour, Dutch-processed cocoa powder, baking soda, and salt directly into the wet ingredients.
  5. Use a spatula to fold the mixture together until just a few streaks of flour remain; do not overmix.
  6. Fold in the bittersweet chips and semi-sweet chunks until evenly distributed.
  7. Scoop rounded tablespoons of dough onto parchment-lined baking sheets.
  8. Optional: Place the tray in the freezer for 5 minutes before baking for extra thickness.
  9. Bake in the oven until the edges are set but the center remains slightly soft.
