Preheat your oven to 350°F (175°C). Lightly grease your 9×13-inch pan or line it with parchment paper for easy removal later on.
In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth. Add in the eggs along with vanilla extract, whisking again until everything is well combined.
In a separate bowl, mix together the flour, salt, and baking soda. Gradually stir this dry mixture into the wet ingredients using a spatula or wooden spoon until just combined—be careful not to overmix.
Gently fold in the semi-sweet chocolate chips until they are evenly distributed throughout the dough, ensuring every bite is packed with chocolatey goodness.
Spread the dough evenly into your prepared pan using either your hands or a spatula to smooth out the surface before baking.
Bake for 28–32 minutes or until you see a lightly golden top and a toothpick inserted in the center comes out clean or with moist crumbs (not wet batter).
Let the bars cool in the pan for at least 20 minutes before cutting them into squares. This cooling period allows them to set properly, maintaining their shape when sliced.
