1 small batch of any good sweet yeast dough (enough for one standard batch of cinnamon rolls)
Make up the sweet dough and let rise until ready to shape. Dough can be rolled out to fit a 9x13 baking pan or a half sheet jelly roll pan. Grease pan and line with dough so that dough comes about half the way the sides of pan.
Pour cooked pudding onto the dough. Lay the plums on top of the pudding with the skins side down. They can be placed in rows or decoratively, however you choose. Make up streusel and sprinkle over plums to cover. You do not have to use all of the streusel, but it's yummier if you do.
