Grandma’s Plum Cake

From Aunt Norma’s transcription.

2 lbs. Italian plums, halved & pitted
Melted butter
Cinnamon sugar

1. Do not preheat oven.
2. Butter a large, lipped cookie sheet or pan.
3. When Grandma’s Yeast Dough has rested enough, flour a large surface and roll dough out thin until it will fit the pan. Brush melted butter on the top of the dough.
4. Place the halved plums sliced side up so they are fitted all over the top of the dough and bake in a cold oven at 250° for about 20 to 25 min.
5. Before serving, sprinkle the top with cinnamon sugar.
