This recipe was from my Southern Living Incredible Cookies Cookbook, which I used when I was a Southern Living at Home Hostess. These are a down right buttery, delectable bar cookie! I hope you will add these to your new Christmas baking favorites. They have certainly made our list for the past few years!
