In a bowl, combine oats, cranberries, almonds, seeds and cinnamon. Book. In another larger bowl, crush the banana until it is smooth. Add almond milk and honey and whisk. Stir in dry ingredients, folding until well blended.
Lightly coat an 8-by-11-inch baking dish with a cooking spray. Spread the oatmeal evenly in the baking dish. Bake in a preheated oven at 375 degrees F for 30 to 40 minutes or until the top begins to brown.
Allow to cool completely in the baking dish. Cut into bars.
