Method
- Preheat the oven to 350°F and line two baking sheets with parchment paper.
- In a medium bowl, whisk together the flour, baking soda, cornstarch, and salt.
- In a large bowl, whisk the melted butter, brown sugar, and granulated sugar until smooth and glossy. Add the egg, egg yolk, and vanilla and whisk until fully blended.
- Add the dry ingredients to the wet ingredients and stir just until combined. Fold in the chocolate chips. The dough will be soft.
- Cover and chill the dough for 15 minutes.
- Scoop the dough into 2-tablespoon portions and place on the prepared baking sheets about 2 inches apart. Press extra chocolate chips on top if desired.
- Bake for 10 to 12 minutes, until the edges are set and lightly golden and the centers still look slightly soft.
- Cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
Notes
Do not overbake for the softest texture. Chill the dough briefly to reduce spreading. Measure flour carefully. Baked cookies can be frozen for up to 2 months, and unbaked dough portions can be frozen and baked with 1 to 2 extra minutes as needed.
