Ingredients in this recipe on a white and pink background.
  • Banana — use a ripe banana for the best natural sweetness and flavour.
  • Old fashioned rolled oats — these give the best texture for overnight oats. Steel-cut or quick oats will change the texture and liquid ratio.
  • Milk — any milk works: almond, oat, soy or dairy. Choose your preferred variety.
  • Chia seeds — help thicken the mixture and add fibre. Either black or white chia is fine.
  • Maple syrup — adds a touch of sweetness. Honey can be used instead, or drizzled on top when serving.
  • Cinnamon — ground cinnamon pairs beautifully with banana and adds warming flavour.

Variations:

Milk — swap for your favourite plant or dairy milk.

Nuts — add chopped almonds, walnuts or pecans just before serving so they stay crunchy.

Cacao powder — stir in cacao for a chocolate-banana version.

Peanut butter — swirl in peanut or another nut butter for a richer flavour.

How to Make Banana Overnight Oats:

Steps 1-2 of preparing this recipe - mashing the banana in a bowl and adding the remaining ingredients to the banana.

1 – Mash the banana:
In a medium bowl, mash the ripe banana with a fork or potato masher until mostly smooth.

2 – Add the other ingredients:
Add the rolled oats, chia seeds, cinnamon, maple syrup and milk to the mashed banana.

Steps 3-4 of preparing this recipe - whisking the ingredients together and adding them to a jar to be placed in the fridge.

3 – Combine the mixture:
Stir or whisk well so the banana is evenly distributed and chia seeds begin to hydrate.

4 – Refrigerate:
Cover the bowl with cling wrap or divide the mixture into two jars and seal. Refrigerate for at least 6 hours or overnight. Add crunchy toppings just before serving to keep them crisp.

Hint: If the oats seem thick in the morning, stir in a little extra milk to loosen the texture.
