Preheat oven to 350°F and line a 9x13-inch baking pan with parchment paper, leaving some overhang on the sides.
In a medium bowl, whisk together flour, baking soda, and salt.
In a large bowl, whisk together melted butter, granulated sugar, and brown sugar until smooth.
Add eggs and vanilla to the butter mixture and whisk until well combined and slightly thickened.
Stir the dry ingredients into the wet ingredients until just combined and no flour streaks remain.
Fold in the chocolate chips until evenly distributed throughout the dough.
Press the dough evenly into the prepared baking pan, spreading it all the way to the edges.
Bake for 23-25 minutes until the edges are golden brown and the center looks just barely set.
Let cool completely in the pan on a wire rack for at least 1 hour.
Use the parchment overhang to lift the bars out of the pan, then cut into squares with a sharp knife.
