Plum Blueberry Peach Cake

Remember all those plums that were on my tree? One night right before dark I was washing dishes and looked out the window and there were two deer helping themselves to my plums. So I quietly opened the door and ran out after them. They high tailed it through the field. Knowing they would come back when I went to sleep, I picked all of them. Now I have plums running out my ears. I found a recipe for Plum Blueberry upside down cake, yummy!! I added some peaches as well. If any one has any recipes for plums I would love to try them.
