While butter mixture is cooling, combine flour, baking soda, and salt in a medium bowl. Stir and set aside.
Turn mixer (with butter mixture bowl attached) on low. Add eggs, one at a time, mixing completely. Mix in vanilla extract. Add flour mixture to the wet ingredients and mix until combined. Stir in chocolate chips.
Important: Cover bowl with plastic wrap and chill dough for at least 4 hours. It must be COMPLETELY cold before you bake it for these to turn out properly.
Preheat oven to 350°. Line cookie sheets with parchment or silpat liners. It’s gonna be an arm workout to scoop the dough, but tt’s worth it!
Scoop out 1 tablespoon sized balls and place on prepared pans.
Bake for about 8 minutes. They will still look sort of raw, but the bottoms will be golden. Let cool for 5 minutes, and then remove from pans to cool completely.
