Preheat oven to 350 ºF (180 ºC). In a non-stick frying pan over medium heat, sauté cinnamon and apples together in butter until tender. Place three quarters of bread into lightly buttered 8"x 8" (20 x 20 cm) baking dish. Spread apple mixture, cheese and brown sugar evenly over bread. Beat milk and eggs together until frothy and stir in remaining bread. Add to baking dish and bake 45 to 60 minutes until set. Great chilled.
