Why You’ll Love This Recipe:

  • They require minimal preparation – all you have to do is mash a banana, mix it with your other ingredients and pop it in the refrigerator!
  • You can adjust the quantities to your needs – the written recipe serves two, but can easily be halved or doubled!
  • It is ideal for meal prep – they’ll last for three days in the fridge, so you can get a head start on your breakfast for the week.
  • This recipe is so versatile – customise the toppings to your liking. Add dried fruits, nuts, yoghurt or extra banana on top, or enjoy as is.
  • Whether you are a morning person or not, this is the ideal breakfast for busy, time-poor people, or those of us who just like a slower start to the day. All the preparation happens the night before, and your breakfast will be ready to enjoy once you hop out of bed!

Recipe Inspiration: these Banana Cinnamon Overnight Oats are delicious, nutritious, easy to prepare and will set you up for a productive day. They’re the perfect use for a banana that is a little too ripe for eating.

Ingredients and Substitutions:

Please see the recipe card further along in the post for exact quantities of ingredients and the full method.

Ingredients in this recipe on a white and pink background.
  • Banana – for the maximum natural sweetness, use a ripe banana. Bananas are at their best for this recipe when they are in between the eating and baking stage!
  • Old Fashioned Rolled Oats – these are the best oats for this recipe. Steel-cut oats and quick-cooking oats can be used in overnight oats recipes, but may have a different ratio of liquid, and will produce a different texture.
  • Milk – use a milk of your preference. I like to use almond or oat milk, but soy milk works just fine as does dairy milk.
  • Chia seeds – helps give the oats a nice thick texture, and also add some extra fibre. Black or white chia seeds are fine to use in this recipe.
  • Maple syrup – for a hint of extra sweetness. You could also use honey, but I would drizzle this on top when serving instead.
  • Cinnamon – ground cinnamon works so well with banana, and adds a lovely warmth of flavour to the oats. A little sprinkled on top before serving is also a nice touch!

Variations:

Milk – you can use any milk of your choice in this recipe.

Nuts – I like to serve the Banana Overnight Oats with some chopped almonds. I add these just prior to serving so they do not go soft.

Cacao powder – for Chocolate Banana Overnight Oats.

Peanut butter – for Banana Peanut Butter Overnight Oats. Or, use a nut butter of your choice.

How to Make Banana Overnight Oats:

Please see the recipe card further along in the post for exact quantities of ingredients and the full method.

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 banana using a potato masher or fork.

2 – Add the other ingredients to the banana:
Add the cinnamon, chia seeds, rolled oats, maple syrup and almond milk to the 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:
Whisk or stir the mixture well to combine.

4 – Refrigerate:
Cover the bowl with cling wrap, or divide the mixture into two glasses or mason jars and cover. Refrigerate for 6 hours or overnight.

Hint: add toppings like nuts when serving, so that they don’t soften.

Tips for Success, Storage and FAQs:

How long will the Banana Cinnamon Overnight Oats last?

For the best taste and texture, enjoy them within three days.

How long do the Oats have to be in the fridge before consumption?

Refrigerate your overnight oats mixture for at least 6 hours. I make mine just before bed and they’re perfect in the morning!

Are Old Fashioned Rolled Oats Gluten-Free?

There are different rules regarding this, depending on where you live in the world. For Australian residents, Coeliac Australia is a great resource on this topic. Always be sure to read the labels and consult with a health professional if you are unsure.

Top Tip:

These Banana Cinnamon Overnight Oats could not be more simple to prepare. As there are such few ingredients, I do recommend using the best quality available.

Serving Suggestions:

One of my favourite parts of making these Banana Cinnamon Overnight Oats, is customising the toppings!

For this recipe, I like to use a topping of Greek yoghurt, chopped almonds, coconut flakes and some additional sliced banana.

You could also try:

  • Chopped walnuts (for a Banana Bread Overnight Oats!)
  • Coconut yoghurt, to keep the recipe vegan.
  • A drizzle of coconut cream and a sprinkle of additional cinnamon.
  • Fresh or dried fruit of your choice.

Enjoy these delicious Banana Cinnamon Overnight Oats. I hope you’ll love the ease of preparation and great taste – be sure to let me know what you think in the comments below!

Please note:

For accuracy, when weights are provided, we recommend weighing your ingredients. This will produce the best results. All oven temperatures listed are for fan forced.

Ingredients

For the Overnight Oats:

  • 1 large banana – ripe See Note 1
  • 1 cup (80 g) old fashioned rolled oats
  • 1 ¼ cup (300 ml) milk – I use almond or oat See Note 2
  • 1 tablespoon chia seeds See Note 3
  • 2 teaspoon maple syrup
  • ½ teaspoon ground cinnamon

Toppings (optional):

  • Greek yoghurt or coconut yoghurt
  • almonds or walnuts – roughly chopped
  • coconut flakes and banana – freshly sliced when serving

Instructions

  • In a medium-size bowl, mash the banana.
  • Add the oats, almond milk, chia, maple syrup and cinnamon to the mashed banana and mix well 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.

Notes

  1. Banana: for the best flavour and sweetness, make sure your banana is ripe.
  2. Milk: use milk of your choice. I use almond or oat milk. Add more milk when serving if you prefer a thinner texture.
  3. Tablespoon: we use a standard Australian tablespoon which is 20 ml (4 teaspoons). For readers located elsewhere in the world, please use 1 tablespoon + 1 teaspoon for each tablespoon listed.
  4. Toppings: the toppings are optional (and are not included in the nutritional information). Use toppings of your liking – see suggestions above.
  5. Storage: for the best taste and texture, enjoy the Banana Overnight Oats within three days.

    Heaven in a bowl! I used whole milk and topped it off with a little whipping cream.

    Instead of syrup, I used a couple squirts of liquid stevia.
