4 c fruit
1/2 c sugar (maybe less for other fruits, but I am using blackberries)
1 stick butter
2 c flour
2 c sugar
2 c milk
Place first 3 ingredients in cast iron skillet. Simmer 20 minutes.
Then in mixing bowl, stir together next 3 ingredients. Pour on top of fruit mixture and transfer cast iron skillet to oven. Bake for 45 minutes at 350 degrees.
