Ingredients

The following ingredients have 45 Servings
  • 1 cup unsalted butter (melted and cooled at least 10 minutes (226g))
  • 1 ¼ cup brown sugar tightly packed ((250g))
  • ½ cup sugar ((100g))
  • 1 large egg + 1 yolks ((room temperature preferred)*)
  • 1 ½ teaspoon vanilla extract
  • 2 ¾ cups all-purpose flour ((350g))
  • 2 teaspoons cornstarch
  • 1 teaspoon baking soda
  • ¾ teaspoon salt
  • 1 ¾ cup semisweet chocolate chips ((plus additional for tops, optional) (300g + additional))

Instruction

  • Combine melted butter and sugars in a large bowl. Stir very well.
  • Add egg and egg yolk, stir well. Stir in vanilla extract. Set aside.
  • In a medium-sized bowl, whisk together flour, cornstarch, baking soda, and salt.
  • Gradually add flour mixture to wet ingredients -- stir well so that all the flour is absorbed. Stir in chocolate chips.
  • Place dough in refrigerator and chill for 30 minutes.
  • Preheat oven to 350°F (177°C) and prepare cookie sheets by lining with parchment paper.
  • Scoop dough by rounded 1 ½ tablespoon onto prepared cookie sheets, placing at least 2" apart.
  • Bake for 11 minutes -- cookies may still seem slightly soft in the centers, that is OK, they will cook completely on the cookie sheets. Don't over-bake or your cookies will be too hard.
  • If desired, gently press additional chocolate chips into the tops of the warm cookies.
  • Allow to cool completely on cookie sheets.
