Kringle dough is very soft, yet surprisingly easy to work with. The center is a simple filling of nuts, brown sugar and butter, then after baking the Kringle is spread with a confectioners sugar icing and sprinkled with nuts. Serve warm or cold, either way it is absolutely delicious. My sister Linda Stradley shared this recipe from her website What's Cooking America, and it quickly became a favorite with everyone who tasted it.
