A yummy blend of oatmeal, chopped caramels, walnuts and chopped apples make this cookie a winner. The richest version features true caramel candies, but you can substitute caramel-flavored chips in a pinch. They don’t deliver the same gooey sweetness as the candy, but the flavor comes close. Because of the apple, these cookies are moist. Store in layers separated by parchment sheets. Refrigerate if you plan on storing them beyond a few days—if they last that long. For a variation, try different nuts, including black walnut, hickory or pecans.
