Butter the sides of a loaf pan.
Cut the bread slices into strips. Halve the apples and cut into thin slices.
In a small bowl, mix the cinnamon and brown sugar.
Prepare an egg mixture by beating the eggs, milk and vanilla extract together in a jug.
Layer the bread in the loaf pan and pour over some of the egg mixture to cover the bread.
Follow with a layer of apple slices and a tablespoon of the cinnamon and sugar mixture.
Repeat the layers of bread, egg mixture, apple slices and cinnamon sugar until you reach the top of the pan. Pour over any remaining egg mixture.
Cover with aluminium foil and refrigerate overnight until ready for baking in the morning.
Preheat the oven to 180°C, gas mark 4.
Bake covered with the foil for 40 minutes, uncover and bake for a further 10 minutes until the top is golden brown and the egg mixture is set.
Drizzle with honey or maple syrup and serve.
