Prune plums, cut in half. Set aside
Soften yeast in water. Add sugar, milk and salt to yeast and mix. Add eggs and blend. Gradually add flour to yeast mix to form a stiff dough. Knead on floured surface until smooth and satiny. Place in greased bowl; cover. Let rise in warm oven (85-90 deg.) until light, about 1 hour. Punch down and roll out onto greased cookie sheet. Place the plums on top, cut side up. Sprinkle with cinnamon sugar. Cover with wax paper. Let rise again until light.
Bake at 350 deg. for 20 minutes, or until nicely brown. Can be served as is, or with whipping cream or cool whip.
Enjoy!
