If you want to give a swirl effect: take a little spatula or a knife and cover the sides of the jar with peanut butter.
Place the oats into a jar, add the milk, cinnamon and honey. Mix with a spoon. Add the peanut butter and stir again. Close the lid and keep in the refrigerator at least 3-4 hours or overnight. When ready to eat, put the sliced bananas over the oats and add additional peanut butter if you like. (As this recipe is very filling, you can divide the mixture in 2 small jars.)
