My mother and grandmother used to make this cake. My grandmother came to America in 1904 from the Burgenland in Austria, and she called this Viennese Plum Cake, so that's what we call it. It has a firm, almost dry texture, but is rich with butter and eggs. I often make this cake with fresh sliced peaches. While sliced apples also work, I think plums, peaches, and apricots are the better complement with this particular cake.
