(I add 1 teaspoon cinnamon and 1/2 teaspoon nutmeg.)
In large bowl mix together apples and sugar with a dusting of flour. Put into a 9 x 13 inch pan. Melt butter and stir in oatmeal until well coated. Sprinkle over apples. Bake in a preheated 350 degree oven until mixture bubbles in the middle, about 50 to 60 minutes. Serve hot, topped with vanilla ice cream. Serves 10 to 12.
