  2. Whisk together the flour, baking soda, cornstarch, and salt in a large bowl.
  3. Mix the melted butter, light brown sugar, and granulated sugar until smooth in a medium bowl.
  4. Add the egg, egg yolk, and vanilla extract to the butter-sugar mixture and whisk until glossy.
  5. Combine the wet and dry ingredients until just incorporated.
