Roll a large piece of the mixture used for apple cake into a rectangular shape from 1/4 to 1/2 inch thick, brush with butter, sprinkle with sugar and cinnamon and, if desired, with raisins or chopped nuts. Roll like a jelly roll, and place the two ends together on a cooky sheet so as to form a ring. Try, if possible, to conceal the joining by fastening the ends together carefully. The best way to do this is to cut a slice from each end before joining. Then, with a scissors, cut through the edge of the ring nearly to the center and slightly at a slant.
Make the cuts about 1 inch apart and turn the cut slices over so as to show the layers of dough. Brush with milk, dredge with sugar, and bake for about 1/2 hour. When baked, this cake should appear as below.
