These Oatmeal Walnut Cookie have a wonderfully chewy texture and a want-at-least-one-more taste. If we start dreaming about them then we know it's time to make them again. When we're being smart, we don't bake all of the dough at one time. Instead, freeze a few balls of dough for baking at a later date.

"The oats make these cookies nicely chewy. I used dark brown sugar because it has more molasses than light, which to me, gave the cookies a more traditional oatmeal cookie texture and flavor. I froze some unbaked shaped cookie dough for when the next craving hits." —Diana Andrews

Tips

Most cookie recipes call for "ungreased cookie sheets." For those recipes, we recommend spraying your cookie sheet with cooking spray and wipe away any excess oil with a paper towel. This way you don't have to worry about scraping your cookies off the pan.
