1 cup sifted flour
1/2 cup sugar
1 tsp. baking powder
1/4 tsp. nutmeg
1/2 cup milk
1 tablespoon oil
8 - 10 Italian plums
Approximately 1/2 tablespoon butter
Grease and flour a 9 inch square pan. Preheat oven to 350 degrees.
Place flour, sugar, baking powder, salt and nutmeg in large bowl and mix thoroughly together. Put milk, oil, and egg into a measuring cup and whisk together with a fork. Pour the liquid into the dry ingredients, stir to blend, and then stir 100 times with a large spoon such as a wooden spoon.
Cut up the fruit and sprinkle with some cinnamon-sugar (you can do this during the first 10 minutes of baking.) It’s a good idea to have some cinnamon-sugar in a sprinkler for this and other projects.
Pour the batter into the pan, and bake at 350 degrees for 10 minutes. After the 10 minutes of baking, remove cake from oven only long enough to arrange fruit on top, sprinkle with more cinnamon-sugar, and dot with butter. Bake for another 40 minutes, until golden brown. You can optionally sprinkle more cinnamon-sugar on the cake half way through the 40 minutes of further baking.
Some of the plums will sink into the batter, others will remain visible.
