Apple-Cinnamon Flapjack Bake

Somewhere between a cake, a cobbler, a flapjack, and a frontiersman's perfect plate is where this Apple Cinnamon Flapjack Bake lands. Best enjoyed straight out of the cast-iron skillet, but for those not moseying along the dusty trail, it can also be made in any oven-safe pan. Eat it at sunrise with a few walnuts sprinkled over top, or wait until sundown and add a scoop of vanilla ice cream.
