Apple Crumble

Serves 18

18 whole Granny Smith apples, peeled, cored, and sliced
3/4 cup sugar substitute (see notes)
6 tablespoons flour
3 tablespoons lemon juice
3 tablespoons cinnamon
7 1/2 cups rolled oats (look for whole oats)
2 1/4 cups walnuts, roughly chopped
1 1/2 cups brown sugar
18 tablespoons butter, cold, cut into 1″ pieces

Preheat oven to 350 degrees. Toss apple slices with sugar, flour, lemon juice and cinnamon and spread in a lightly greased glass baking dish. Process 1 cup of the whole oats in the food processor to make oat flour, then mix with the remaining oats, walnuts and brown sugar. Using a pastry cutter or your fingers, work the butter into the dry ingredients, leaving a few small lumps of butter in the mixture. When the topping looks crumbly, pour on top of the apples and bake until golden brown and apples are cooked and bubbling, about 30-45 minutes.
