Adjust the oven racks to middle position.
Preheat oven to 350 Degrees Fahrenheit.
In the small sized measuring bowl, whisk together the all purpose flour, baking soda and salt.
Add the butter to the saucepan, and put the pan over medium heat. Cook the butter until it starts to brown. Transfer the butter to the medium sized bowl and allow to cool.
In the large mixing bowl, add the dark brown sugar and granulated sugar.
Pour the cooled butter into the sugar mixture, and mix until combined. Note: You can mix this either by hand with a whisk, or you can use an electric mixer. Add the egg, egg yolks, and vanilla extract to the sugar/butter mixture. Whisk until smooth and thick.
Add the dry ingredients and fold in using a rubber spatula until a cookie dough forms.
Mix in the chocolate chips.
Line your baking sheets with parchment paper.
Using the scoop, scoop out portions of dough. Note: If you don't have a scoop, you can use a 1/4 cup dry measuring cup.
Add 6 scoops of cookie dough to the baking sheet, evenly spaced apart.
Bake for 10 minutes, or until the edges are golden brown, and remove from oven.
Allow the cookies to stay on the baking sheet for 10 minutes before transferring to a cooling rack.
