Christmas cookie, oh Christmas cookie, how ever sweet you taste! Especially if you happen to be maple walnut butterballs, which are easy little concoctions just begging to be enjoyed with your favorite cup of Christmas tea. They are those delectable little melt in your mouth type of cookie, made with ground walnuts and butter and just enough maple syrup to sweeten them up. I promise that you won't even mind when the powdered sugar that they are rolled in gets on your shirt, because the dreamy taste is all you will care about. Let's make them!
