01 - Preheat the oven to 350°F. Line a 9x13-inch baking pan with parchment paper, leaving a slight overhang for easy removal.
02 - Whisk together all-purpose flour, baking soda, and sea salt in a medium bowl. Set aside.
03 - In a large bowl, whisk melted butter with light brown sugar and granulated sugar until smooth and glossy.
04 - Add eggs one at a time to the wet mixture, whisking thoroughly after each addition. Stir in vanilla extract.
05 - Fold the dry ingredients into the wet ingredients using a spatula until just blended; do not overmix.
06 - Gently fold semisweet chocolate chips evenly into the batter.
07 - Spread the batter uniformly into the prepared pan, smoothing the surface with a spatula.
08 - Bake for 22 to 25 minutes until edges turn golden and a toothpick inserted in the center comes out with moist crumbs.
09 - Allow to cool completely in the pan placed on a wire rack. Lift out using parchment overhang and cut into 16 bars.
