The worlds best chocolate chip cookies.

I have it from several sources that this is indeed the worlds best chocolate chip cookie. There are a couple of key points, that I think make a difference.

1)Use chocolate chunks, not chips. Usually I use Nestle semi-sweet brand, nothing fancy.
2)Melted butter not softened butter. I don't know why this really makes a difference but it does.

Now for the recipe...

Preheat oven to 350

DRY INGREDIENTS2 1/2 cups all purpose flour
1 tsp baking soda
1 tsp salt

WET INGREDIENTS3/4 cup white sugar
3/4 cup brown sugar
1 cup unsalted butter -melted and slightly cooled (yes, that's 2 sticks)
2 large egg yolks
1 tsp vanilla extract

Sift dry ingredients together.
In another bowl combine sugars and butter thoroughly
Add egg yolks and vanilla and combine.
Add wet ingredients to dry and stir until batter comes together (don't try and stir it smooth).
Stir in 1- 12oz package of chocolate chunks

Drop by rounded spoonful onto an ungreased cookie sheet and bake for 11-12 minutes or until they turn light brown. Do not let them get golden brown, that will overcook them. Let the cookies cool for a few minutes and then transfer them to a cooling rack. This makes around 30 cookies.
