Preheat oven to 350F, spray a mini muffin pan and set aside.
In a bowl mash your bananas, add in your milk, egg and vanilla and mix well. Stir in your sugar, oats, cinnamon and baking powder.
Fold in your raisins, nuts, seeds and coconut.
Fill to the top in your mini muffin pan. Batter won't be thick, and have more of a liquid texture.
Bake in the oven for approx. 16-18 minutes. Carefully use a knife to get the muffins out of the tin. Yields 36 mini muffins. Store in a sealed container in the fridge, you can freeze muffins.
