The Finest Oatmeal Cookie Bars

Filed Under: dessert February 26, 2024

Jump to Recipe·Print Recipe

I love cookies, but sometimes I don’t have time to scoop out all the individual cookies. So I realized, similar to sheet pan pancakes, making cookie bars is much much easier. You make all the dough, cook it, then slice it! It doesn’t help that these Oatmeal Cookie Bars are absolutely delicious and helped me to use up that huge container of old fashioned oats I bough on sale.

    I’m wondering if it should be in a 9X13 pan instead? I made the recipe, as noted in a 9X9 and it was still liquid at 25 minutes. It then burnt when I tried to cook it longer. It smelled amazing, just didn’t work for me. Thanks.

      Hi Angela, I’m so sorry these didn’t work for you! 9×9 is correct. I know that oven temps often vary and you might find that if you take them out when they still seem a little gooey, they will continue to cook in the pan until they are cool and sliced. I’ll make sure to note this in the recipe going forward. I appreciate you trying my recipe though! Hope you might give it another shot!
