Preheat oven to 325F and generously grease a 13x18” sheet pan (you can use parchment paper, but I find it easier to spread cookie dough without it).
In a medium bowl, whisk all-purpose flour, sea salt, baking powder and baking soda and set aside.
In the bowl of a stand mixer add sugars and melted butter OR combine with a spatula and allow it to sit for a couple minutes to absorb some butter into the sugars.
Add eggs and pure vanilla extract. Run on medium speed for about 30 seconds.
Mix dry ingredients into the wet ingredients by running on low for about 1 minute with the paddle attachment (I like to do this in two steps because it is a lot of dry ingredients and prevents it from making a mess by flying up).
Add chocolate chips to the mixer and run again (I also like to do this in 2 steps for more even distribution).
Transfer dough to the prepared pan and spread evenly using an offset spatula or your hands (if you have a pastry roller, this works well too).
Bake for about 15 minutes or until the edges start to become golden and a toothpick comes out with moist crumbs.
Place tray on a wire rack to cool before slicing for at least 10 minutes. I find it easier to slice in the pan, but you can risk scratching it. If you want to remove cookie from pan and almost cool you can place a wire rack overtop, flip it, place a cutting board on top and flip again.
Slice into any desired sizes.
