Total Time 32 minutes
Servings: 22 servings

Ingredients
  

  • 2 1/4 cups all-purpose flour
  • 1 teaspoon baking soda
  • 3/4 teaspoon salt
  • 3/4 cup unsalted butter softened to room temperature
  • 1 cup packed light brown sugar
  • 1/2 cup granulated sugar
  • 1 large whole egg room temperature
  • 3 large egg yolks room temperature
  • 1 tablespoon vanilla extract
  • 2 cups dark chocolate chips

Method
 

  1. Preheat oven to 325°F and line two baking sheets with parchment paper or silicone mats.
  2. Whisk together flour, baking soda, and salt in a bowl and set aside.
  3. In a large mixing bowl, beat butter, brown sugar, and granulated sugar on medium speed until creamy and smooth, about 3 minutes.
  4. Add the whole egg and egg yolks one at a time, beating well after each addition, then mix in vanilla extract.
  5. Reduce mixer speed to low and gradually add the flour mixture, mixing just until no dry streaks remain.
  6. Fold in dark chocolate chips using a rubber spatula until evenly distributed throughout the dough.
  7. Scoop dough into 2-tablespoon portions and place 2 inches apart on prepared baking sheets.
  8. Bake for 13-14 minutes until edges are set and lightly golden but centers still appear very soft and underbaked.
  9. Allow cookies to cool on the baking sheet for 8-10 minutes before carefully transferring to a wire rack to cool completely.
