These chewy brown butter chocolate chip cookie bars are a quick and easy lunchbox treat with a rich, nutty flavor and perfect chewy texture.
Keep a close eye on the butter while browning to avoid burning. Use room temperature eggs to prevent curdling. Do not overmix the batter to maintain chewiness. Let bars cool completely before slicing for best texture. Tent with foil if edges brown too quickly.
