Preheat your oven to 350°F (175°C). If using, line your sheet pan with parchment paper for easy removal.
In a mixing bowl, whisk together the flour, baking soda, and salt. Set aside.
In a separate large bowl, cream together the softened butter, brown sugar, and granulated sugar until the mixture is light and fluffy.
Beat in the eggs one at a time, followed by the vanilla extract, mixing well after each addition.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix.
Fold in the chocolate chips with a spatula until evenly distributed throughout the dough.
Spread the cookie dough evenly in the prepared sheet pan, smoothing the top with the spatula.
Bake in the preheated oven for about 25 minutes, or until the edges are golden and a toothpick inserted into the center comes out clean or with a few moist crumbs.
Allow the cookie bars to cool in the pan on a wire rack for about 10-15 minutes. Then, transfer the bars to the cooling rack to cool completely before cutting into squares.
