Here is the basic apple crumble recipe.
1/3 cup butter or margarine
1 + 1/4 cup brown sugar
2/3 cup flour
1/4 tsp cinnamon.
Mix together until well blended. Sprinkle over apple slices in a deep dish. Bake at 375 F for 40 minutes.
I just dolloped a bit of frozen dulce de leche around on top of the apples before the topping. It melted through and blended with the juices to make a nice mild caramel flavour. You could probably do it with store bought caramel sauce, as well.
I also substituted half of the flour for quick cooking oatmeal, just to give it more texture. It turned out very nice and complimented the pork chops we had for dinner quite well.
I still have plenty of the dulce de leche leftover, so i may get another bag of apples and make this again. So long as i do not lose them in the crisper this time, i should be good to go!
