Enjoy the ultimate treat with these bars, featuring a rich, buttery dough loaded with gooey chocolate chips. Easy to make and perfect for any occasion, these bars deliver a deliciously satisfying dessert everyone will love!
Preheat the oven to 325 degrees. Adjust the oven rack to lower-middle position.
Line a 9X13-inch baking pan with foil. Allow the excess to hang over the edges of the pan by about 1 inch so you can grab those edges and pull the bars from the pan after they've baked. Spray the foil-lined pan with nonstick cooking spray.
Mix the flour, salt, and baking soda together in medium bowl; set aside. In a large bowl, whisk the melted butter and sugars until combined. Add the egg, egg yolk, and vanilla and mix well.
Using a rubber spatula, fold the dry ingredients into the egg mixture until just combined; do not overmix. Fold in the chocolate chips and add the batter into the prepared pan, smoothing the top with the spatula.
Bake until the top of the bars are light golden brown, slightly firm to the touch, and edges start pulling away from sides of pan, 24-28 minutes. Cool on a wire rack to room temperature.
Remove the bars from the pan by lifting the foil overhang and transfer them to a cutting board. Cut into squares and serve.
