Combine the mashed banana, eggs, ground flax seed, salt, milk, cinnamon, vanilla and molasses in a small mixing bowl. You can even substitute an equal amount of honey for the molasses if you want, but it's not necessary, you can leave it out completely. In a larger bowl mix the oats with the chopped apples(with or without skins), the chopped dates and the walnuts. Mix well being sure the dates are evenly combined with everything else as they stick together and you want them evenly spread out in the whole dish. Pour in the wet ingredients and mix well. Pour into the prepared pan and bake at 375 for 30-35 minutes. You can top with a sprinkling of extra cinnamon before baking if you like. Leave it to cool for 10-15 minutes before serving, if you can wait that long :D Serve with extra milk and a drizzle of honey or maple syrup.
