Old-School Peanut Butter Cookie Bars (Lunch Lady Style)<\/strong>
There\u2019s something timeless about classic cafeteria desserts\u2014simple to make, big on flavor, and crafted to feed a crowd. These Peanut Butter Cookie Bars are a modern spin on those nostalgic lunch lady treats, and they\u2019re every bit as crave-worthy.<\/p>\n

Unlike cookies that require scooping and chilling, these bars are baked in a single sheet pan. No fuss, no waiting\u2014just spread the batter and bake. The end result? Buttery, peanut-butter-packed bars with a soft, almost brownie-like texture that melts in your mouth.<\/p>\n

And then comes the glaze. A warm, creamy peanut butter frosting is poured over the cooled bars, soaking in just enough to create a rich, sweet top layer that sets beautifully. These bars disappear fast\u2014especially if friends or family catch wind of them.<\/p>\n
