Peel apples and slice into 4 quarters. Slice each quarter into thin slices.
In a bowl large enough to hold the apples, mix together white sugar, 1 tablespoon flour, cinnamon, and nutmeg. Add the apples and mix until the apples are coated in the mixture.
Place the apple mixture into a greased 4-quart baking dish or a deep 9x15 casserole dish.
In a seperate bowl combine 2 cups flour, brown sugar, and melted butter. Crumble evenly over the apple slices.
Bake for about 45 minutes and cool slightly. Serve warm with vanilla ice cream.
