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.

In another bowl, mix the melted butter, brown sugar, granulated sugar, and vanilla extract until smooth.

Add the eggs one at a time, mixing well after each addition.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Fold in the chocolate chips.

Spread the batter evenly in the prepared baking pan.

Bake for 20-25 minutes or until the edges are golden and a toothpick inserted in the center comes out clean.

Allow to cool in the pan before cutting into squares.
