How to make this recipe
Scroll to the bottom of this post (or use the 'jump to recipe' button at the top) to see the full recipe with exact amounts!
You need to make these overnight oats the night before you plan to eat it (or at least 5 hours in advance).
- Mash up the banana in a bowl - adding mashed banana to overnight oats adds so much flavour and natural sweetness and works as a thickener.
- Add the oats - if you have coeliac disease or a severely gluten-intolerant, make sure your oats are gluten-free certified.
- Add the milk - you can use any type you like, such as almond milk, cashew milk, soy milk, rice milk, oat milk etc.
- Mix well, cover the bowl with a plate or cling film, and keep in the fridge overnight or for at least 5 hours.
- It might seem like you'll be adding a lot of liquid, but it all gets soaked up by the oats. If the oats still look dry the next morning, you can add extra milk before eating.
- Adding the mashed banana means that the oats will have turned brown by the time you eat them the next morning. This is completely natural, it is still ok to eat and the taste won't be at all affected.
Ingredients you can add
This Banana Overnight Oats recipe provides a basic template that you use and customise to suit your dietary requirements and taste preferences.
Here are some ingredients you can add when preparing the oats:
- Yogurt - any type of plant-based yogurt such as coconut or almond yogurt will work to thicken the mixture and make it even creamier.
- Nut butter - peanut, almond or cashew butter.
- Cinnamon - for a warm, toasty flavour.
- Dried fruit - raisins, dried cranberries, chopped dates, or dried pineapple, papaya or mango for a tropical vibe.
- Coconut - desiccated coconut adds some nutty fragrance.
- Maple syrup - or any other sweetener for extra sweetness.
- Chopped nuts - walnuts, brazil nuts, almonds, pecans, macadamia nuts or pistachios.
- Coconut flakes.
- Fresh fruit - raspberries, strawberries, blueberries, blackberries, cherries etc.
- Cacao nibs.
How long do these Banana Overnight Oats keep for?
These Banana Overnight Oats must be stored in the fridge and are best eaten the day after they're made.

What a great idea to add a mashed banana - can't wait to make this soon!
Made this once and now I think I'll have it evey morning!
That's great, thank you so much!
How much oats and how much milk in US measurements. Please.
If you click on the 'US Customary' button below the ingredients list you can switch back and forth between measurements. Hope that helps!
I have been having overnight porridge for a while now but never thought to use banana until reading your recipe. So sweet and tasty thank you! I love mine with coconut milk 😊
That's great! Thank you for letting me know!
I've never understood the appeal of overnight oats, but this has now become my favourite breakfast! I love the fact that you can customise it with whatever you have in the fridge or cupboard. It's a great way to use up grapes that are going a bit soft (sliced in half). I've also made it using muesli, which works really well too. I'm going to try adding peanut butter next... It's such a treat to wake up to a ready-made breakfast that is so nutritious and filling.
Thank you so much, so happy to hear that!!
