Place all ingredients, except for banana and maple syrup into pint sized jar or container. Give the ingredients a good stir, to fully mix together.
Once mixed together, add banana slices. Drizzle with maple syrup, if using, (maple syrup is optional, use if a sweeter taste is desired) to jars. Stir. Once ALL ingredients are mixed together, add additional milk (if desired) to loosen up the oats a bit, then stir well, to blend.
Cover jars with plastic wrap, and refrigerate overnight. When ready to serve, garnish with additional banana slices (if desired). Oats will keep for 2-3 days when stored tightly covered in refrigerator.
Maple syrup is optional, if a sweeter taste is desired. It is not calculated in the caloric count.
