I have a few food posts coming up that I've been neglecting!
We made this about two weeks ago when Dave and Sharon came over. We used the last of the apples from apple picking. I sliced them, stuck them in a pan, and sprinkled chunks of butter on them. Then I mixed together 1 cup oats, 1/2 cup brown sugar, 1/2 cup butter, 1/2 cup white sugar, and 1/2 cup flour, mixed it together, and sprinkled it on top of the apples. I baked it at 350 for about 1 hour.
When it comes out, it looks like the topping isn't done, but it is! The apples are soft, and the topping is buttery and crumbly! Delicious!
