Preheat oven to 330°F. (YES, 330 degrees, that's not a type-o)
Sift flour, baking soda, and salt into a large bowl and set aside.
Combine butter, brown sugar, and powdered sugar in a separate bowl and cream with an electric mixer until fluffy.
With the mixer running, add eggs, one at a time, then add vanilla. Mix until combined, scraping the sides of the bowl.
Slowly add the flour mixture, scraping the sides of the bowl. Stir in chocolate chips.
Scoop 2 tablespoons for medium cookies or 1/4 cup cookie dough balls for large cookies onto an ungreased baking sheet (I cover mine with parchment paper).Note: if making large cookies, only bake 3-4 cookies per cookie sheet
Bake until light golden, 12 minutes for medium cookies, and 15-16 minutes for large.
Let cookies cool on cookie sheets for 3 minutes then transfer to a wire cooling rack.
