Ingredients:

  • 1 cup (227g) unsalted butter, melted and slightly cooled
  • 1 cup (200g) dark brown sugar, packed
  • 0.5 cup (100g) granulated white sugar
  • 2 tsp pure vanilla extract
  • 1 large egg, room temperature
  • 1 large egg yolk, room temperature
  • 2.25 cups (280g) all-purpose flour
  • 1 tsp baking soda
  • 0.5 tsp fine sea salt
  • 2 cups (340g) semi-sweet chocolate chips

Instructions:

  1. In a large bowl, whisk together the melted butter, dark brown sugar, and granulated sugar vigorously for about 1 minute until the mixture looks glossy. Note: This helps the sugar start to dissolve into the fat.
  2. Add the egg, egg yolk, and vanilla extract. Whisk until the batter is smooth and slightly lightened in color.
  3. Sift the all purpose flour, baking soda, and fine sea salt directly into the wet ingredients.
  4. Use a silicone spatula to fold the mixture until just a few streaks of flour remain. Note: Stop early to keep the cookies tender.
  5. Fold in the chocolate chips until they are evenly distributed throughout the dough.
  6. Preheat your oven to 375°F (190°C) and line your sheets with parchment paper.
  7. Scoop rounded tablespoons of dough onto the sheets, spacing them 2 inches apart.
  8. Bake for 9–11 minutes until the edges are golden and set but the centers look pale.
  9. Allow cookies to rest on the sheet for 5 minutes until they firm up before moving them.
