Ingredients:

  • 290g all-purpose flour
  • 1 tsp baking soda
  • 0.5 tsp fine sea salt
  • 170g unsalted butter, melted and cooled
  • 200g packed light brown sugar
  • 100g granulated white sugar
  • 1 large egg, room temperature
  • 1 large egg yolk, room temperature
  • 2 tsp pure vanilla extract
  • 300g semi-sweet chocolate chips
  • 1 tsp flaky sea salt (optional topping)

Instructions:

  1. Melt the 170g butter. Allow it to cool until it is no longer hot to the touch but still liquid.
  2. Whisk the melted butter with the brown and white sugars in a large microwave-safe bowl for approximately 1 minute until the mixture resembles wet sand and no streaks of oil remain.
  3. Add the whole egg, the extra egg yolk, and the vanilla extract. Whisk vigorously until the batter becomes pale, slightly thickened, and shows a glossy sheen on the surface.
  4. Using a silicone spatula, gently fold in the dry base (flour, baking soda, and sea salt) until just combined, being careful not to overmix.
  5. Fold in the chocolate chips or hand-chopped chocolate chunks until evenly distributed throughout the dough.
  6. Cover and refrigerate for at least 30 minutes.
  7. Scoop the dough into rounded tablespoons and place on prepared baking sheets. Bake at 325°F for 10 minutes or until edges are mahogany-colored and the centers remain soft.
