- 2 cups all-purpose flour
 - 2 cups rolled oats
 - 1 teaspoon ground cinnamon
 - 1/2 teaspoon ground nutmeg
 - 1 1/2 cups packed brown sugar
 - 1 1/2 cups butter
 - 2 quarts peeled, cored and sliced apples
 
- Preheat oven to 350 degrees F (175 degrees C).
 - In a large bowl, combine the flour, oatmeal, cinnamon, nutmeg and brown sugar. Cut butter into mixture until crumbly.
 - Take half of the mixture and pat it into the bottom of a 9x13 inch baking dish.
 - Cover crumb mixture with apple slices, then sprinkle apple slices with remaining crumb mixture.
 - Bake at 350 degrees F (175 degrees C) for 45 to 50 minutes or until apples are tender.
 
One thing I noticed is that cooking for this long tends to make the apples more like a chunky sauce (see my picture). It is still good, but the apples are a bit over cooked. I would do it for about 30 minutes and then check it from there to see if the crumble is nice and crisp.
