For the Overnight Oats:

  • 1 large banana - ripe See Note 1
  • ¼ cup peanut butter See Note 2
  • 1 tablespoon maple syrup
  • 1 cup (80 g) old fashioned rolled oats
  • 1 ¼ cup (300 ml) milk - I use almond or oat See Note 3
  • 1 tablespoon chia seeds See Note 4

Toppings (optional):

  • Greek yoghurt or coconut yoghurt
  • peanuts - roughly chopped
  • coconut flakes and banana - freshly sliced when serving


  • In a medium-size bowl, mash the banana.
  • Add the peanut butter and maple syrup to the banana and mix until well combined.
  • Add the milk, oats and chia seeds and stir to combine.
  • Cover the bowl with clingwrap, or divide the mixture into two glasses or mason jars and cover. Refrigerate for 6 hours or overnight.
  • Serve with toppings of your choice and additional milk if the mixture is too thick.


  1. Banana: for the best flavour and sweetness, make sure your banana is ripe. 
  2. Peanut Butter: use smooth or crunchy - whatever you prefer. 
  3. Milk: use milk of your choice. I use almond or oat milk. Add more milk when serving if you prefer a thinner texture.
  4. Tablespoon: we use a standard Australian tablespoon which is 20 ml (4 teaspoons).
  5. Toppings: the toppings are optional (and are not included in the nutritional information). Use toppings of your liking - see suggestions above.
