I found this on-line and thought about trying it. The source says NY Times, but you never know with recipes and the internet! Here goes:

• c. Italian (prune) plums, halved (Use these plums only.)
• 1 1/2 tsp. cinnamon (I often use a little more)
• 1/4 c. sugar
• 1 1/4 c. sugar
• 4 large eggs
• 1 c. vegetable oil
• 1/2 c. orange juice (preferably fresh)
• 1 tsp. vanilla
• 3 c. unsifted flour
• 3 tsp. baking powder
• 1/2 tsp. salt

Preheat oven to 350 degrees.

Butter (or whatever) a bundt pan.

Sprinkle plums with cinnamon & 1/4 c. sugar.

Beat eggs, add sugar, then oil, then OJ and vanilla. Sift dry ingredients together. Combine egg mixture and dry ingredients.

Put 1/3 of the batter in a pan, then 1/3 plums; repeat layers of batter and plums, ending with plums.

Bake for 80 minutes (until golden), let sit for 20 minutes before unmolding.

Dust with confectioner's sugar and enjoy.
