I couldn't decide between making an apple pie or an apple crumble, so I combined them into a mini pie. I cut out circles of pie dough and placed them into buttered muffin tins, spooned in some filling and topped with crumble. I cooked the filling using Cook's Illustrated's Deep Dish Apple Pie recipe since I didn't think the mini pies would be in the oven long enough to cook the apples otherwise.
