I made this for our Friday Night party two weeks ago. Served with ice cream while hot, it was a hit!
For a large group, double the topping and fill 9x13 with peeled/sliced apples.
4 c. sliced apples (4 med)
3/4 c. brown sugar
1/2 c. flour
1/2 c. oats
3/4 t. cinnamon
1/3 c. margarine
Place applies in pie pan. Bake 375 degrees for 30 mins. (My 9x13 pan took a little longer.)
