1 3/4 c. Bisquick
2 tbsp. granulated sugar
2 tbsp. Wesson oil
1 egg
3/4 c. milk or enough to make a smooth batter

Mix all ingredients together and put into a well-greased 9x13 inch glass pan.

Wash and pit prune plums, approximately 25, into quarters to place into batter. Add a little sugar, salt and cinnamon to bring out flavor of fruit. Dot pieces of butter over top of fruit. Cover and bake for 15 minutes at 400 degrees, take off cover and finish baking at 375 degrees until brown. Sprinkle a little sugar over cake when done.
