Preheat oven to 350 degrees and spray a 13”x9” metal baking dish with non-stick spray.
In a large bowl, beat the butter with a hand mixer for 30 seconds to 1 minute until light and fluffy. Add the sugars and beat for another minute.
Add the vanilla extract and eggs and beat until well combined.
Pour the flour, baking soda and salt over the top of the mixed wet ingredients. Starting with the hand mixer on the lowest setting, mix the flour, salt and baking soda together first and then gradually mix it into the wet ingredients.
Increase the speed as needed and mix until all of the dry ingredients are incorporated into the wet.
Add all of the chocolate chips, reserving a handful for topping, and mix the chips into the dough by hand.
Dump the cookie dough into the prepared baking dish. Use a rubber spoon (or your hands) to spread and flatten the dough. Top the dough with the reserved chips.
Bake in the oven for 25-28 minutes until the cookie bars are golden brown.
Allow the bars to cool and set in the baking dish for at least 10 minutes before slicing or removing from the pan.
