**September 2015 Edit - I am so confused by the two terrible reviews below. This is one of my most popular recipes ever. These cookies have turned out perfectly EVERY single time I have made them. I have to wonder if exact altitude makes a difference. So, with that in mind, I am adding that I am at 5900 feet above sea level. If your altitude is different at all...make at your own risk.** As a recent transplant to Colorado I am having to adjust all my recipes to High Altitude. This is my attempt at Oatmeal Raisin Cookies.
