Mash your banana in a bowl that has a lid, or mash into a plate and transfer to a jar. Then add all remaining ingredients and mix well.
Refrigerate overnight, or for AT LEAST 4 hours. Top with fresh fruit, nuts, seeds or any other toppings you'd like and enjoy.
Make sure to use rolled oats or quick oats, NOT instant oats.Double the recipe to have breakfast ready for the next two days, or for sharing.Make it in advance, overnight is best, but a minimum of 4 hours works too.Use a very ripe banana with plenty of brown spots on the peel. Since most of the sweetness is coming from the banana, you want to be sure to choose a super ripe one, especially if you want to omit the maple syrup.Make sure to use certified gluten free oats, if needed, since oats often come into contact with other gluten containing products.Nutritional information does not include optional ingredients.
