Add butter and sugars to mixer bowl and mix until well combined.
Add eggs, one at a time, mixing in between.
Add Vanilla.
Add chocolate chips to the flour and stir. Coating them in flour will keep them from sinking to the bottom of your cookies. Then add to butter, sugars, egg mixture wth baking soda and salt.
Scoop using your desired scoop size onto an aluminum foil lined cookie sheet. A 1" scoop will make approx. 30 cookies and a 2" scoop will make approx. 14 cookies.
Chill in fridge for minimum 1 hour. Desire amount of time is 4-12 hours.
Preheat oven to 350 degrees
Once preheated, cook for the appropriate time based on your cookie size. For Larger cookies bake 12-14 minutes, for smaller cookies bake 9-11 minutes. The edges of the cookies will become slightly stiff and you will just see bits of golden on the cookies. You don't want the bottoms to be dark as they will darken more while cooling.
Cool on pan for 5 minutes before transferring to cooling rack to dry completely.
