Mash bananas in large bowl until you can't see any chunks. Mix in apple sauce, almond milk, vanilla, maple syrup and egg until smooth.
Stir in oats, chia seeds and cinnamon. Beat until well incorporated. Gently mix in cranberries, chocolate and nuts.
Place a heaping Tablespoon of batter at a time onto baking tray and press gently with a fork to flatten.
