Creamy banana cinnamon overnight oats for an easy sweet treat for breakfast.  The oats combine ripe bananas with cinnamon and the optional peanut butter to flavor hearty rolled oats for a filling meal.


  • 1/2 ripe banana, mashed
  • 1/2 cup old-fashioned oats
  • 1/2 cup dairy-free milk
  • 1 tablespoon ground flax seeds or 2 teaspoons chia seeds
  • 2 teaspoons maple syrup
  • 1/4 teaspoon ground cinnamon
  • 1 tablespoon natural peanut butter (optional)


Sliced banana or other fresh fruit

Chopped walnuts, pecans, or peanuts

Chocolate chips

Peanut butter


  1. Mash half a ripe banana in a container with a lid.  Then mix in the rolled oats, dairy-free milk, ground flax seeds, maple syrup, ground cinnamon, and peanut butter (if using).
  2. Stir well and let them soak for at least 2 hours in the refrigerator for the oats to soften.
  3. Before enjoying give the oats a good stir, then add any toppings.


I make multiple at one time and use jars for individual servings.  Multiple servings can also be made together in a large container.  In this case either let is sit to thicken then portion out or keep all of the servings together and remove a portion as needed for breakfast.
