This is a recipe I got from my friend. Donna (made a few changes).
1/2 stick margarine
1 cup flour
1 1/2 tsp baking powder
1/4 tsp salt
1 cup sugar
1 cup milk
3 - 4 cups fresh fruit (I think you could probably use canned fruit filling if fresh fruit is not in season)
Since I used peaches, I added some sugar, cinnamon and nutmeg.
Melt the margarine in the bottom of a casserole or baking dish. Add the flour, baking powder, salt, sugar and milk - stir to blend.
Spoon the fruit on top of the batter - do not stir.
Bake at 350 - about 30 minutes - until browned. The batter rises above the fruit (or the fruit sinks) and makes a crust.
