Ingredients and Substitutions:
Please see the recipe card further down for exact quantities and the full method.

- 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:
Please see the recipe card further down for exact quantities and the full method.

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.

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.

Tips for Success, Storage and FAQs:
They’re best eaten within three days for optimum taste and texture.
Refrigerate for at least 6 hours. Preparing them before bed gives perfect results by morning.
Some rolled oats are processed in facilities that handle gluten. Check packaging if you require gluten-free oats and consult local guidance if unsure.
Top Tip:
With so few ingredients, use the best-quality items you can—ripe bananas, fresh oats and a milk you enjoy—for the most flavourful result.

Serving Suggestions:
Customising toppings is one of the best parts. For a favourite combination, top with Greek yoghurt, chopped almonds, coconut flakes and extra sliced banana.
Other ideas:
- Chopped walnuts for a banana-bread flavour.
- Coconut yoghurt to keep it vegan.
- A drizzle of coconut cream and extra cinnamon.
- Fresh or dried fruit of your choice.
Enjoy these simple, tasty Banana Cinnamon Overnight Oats. They’re quick to prepare, versatile and perfect for mornings when you want a nutritious breakfast with minimal fuss.
