01 - Preheat oven to 350°F. Line a 9x13-inch baking pan with parchment paper, leaving an overhang for easy removal.
02 - In a medium bowl, whisk together flour, baking soda, and salt until evenly mixed.
03 - In a large bowl, whisk melted butter, brown sugar, and granulated sugar until smooth and glossy.
04 - Add eggs one at a time to the wet mixture, whisking after each addition, then stir in vanilla extract.
05 - Fold dry ingredients into the wet mixture with a spatula until just combined without overmixing.
06 - Gently fold in the semisweet chocolate chips, dispersing evenly throughout the batter.
07 - Spread the batter evenly in the prepared pan, smoothing the surface for uniform thickness.
08 - Bake for 22 to 25 minutes, or until edges are golden and a toothpick inserted in the center comes out with moist crumbs.
09 - Allow to cool completely in the pan on a wire rack. Lift out using the parchment overhang and cut into 16 bars.
