Preheat the oven to 350°F (175°C) and grease a 9x13 inch baking pan.

In a mixing bowl, whisk together the flour, baking soda, and salt. Set aside.

In another bowl, cream together the softened butter, brown sugar, and granulated sugar until smooth.

Beat in the eggs one at a time, then stir in the vanilla extract.

Gradually blend the dry ingredients into the wet mixture until just combined.

Fold in the chocolate chips.

Spread the cookie dough evenly into the prepared baking pan.

Bake in the preheated oven for 25-30 minutes, or until the edges are golden brown and a toothpick inserted in the center comes out clean.

Allow to cool in the pan before cutting into bars.
