Using a mixer, mix the butter, brown sugar, and granulated sugar until fluffy.
Add in vanilla and eggs, one at a time, and mix until light and smooth.
Slowly add in the flour, baking soda, and salt with mixer on low speed, until everything is combined.
Fold in chocolate chips.
The mix will come out very liquid, and maybe even a bit sticky. Use a spoon or ice cream scooper to form small dough balls and place them ~2 inches apart on a baking tray. Use your hands or a spoon to slightly flatten the dough.
