I love breakfasts that feel effortless yet still taste like I put real care into them, and Banana Walnut Overnight Oats have become one of my go-to options. Waking up to a jar already filled with creamy oats, natural sweetness, and a hint of nuttiness makes my mornings calmer and more enjoyable. It’s the kind of recipe that fits busy days, cozy weekends, and everything in between.
What I enjoy most is how customizable this breakfast can be. Depending on my mood, I switch up the toppings, add a drizzle of honey, or layer in yogurt for extra creaminess. But even on its simplest version, the combination of banana and walnut feels comforting, wholesome, and energizing—like a gentle way to start the day without rushing or overthinking.
What You Need To Make This Recipe
Old-Fashioned Rolled Oats:
These oats are the best choice for overnight oats because they soften beautifully without becoming mushy. Their texture holds up well and creates that perfect creamy but slightly chewy consistency we all look for in this type of breakfast.
Milk (or milk alternative):
This is the liquid base that hydrates the oats overnight. You can use dairy milk for richness or almond, oat, or soy milk for a lighter, plant-based option. The milk you choose will slightly influence the flavor and creaminess of the final result.
Chia Seeds:
A tiny scoop of chia seeds helps thicken the mixture while adding fiber, protein, and healthy fats. They swell as they sit in the liquid, giving the oats a more pudding-like texture.
Banana:
Mashed banana naturally sweetens the oats and brings a soft, tropical note to the mix. It blends into the liquid and adds creaminess without the need for added sugars. Sliced banana on top adds extra freshness.
Walnuts:
These nuts add crunch, richness, and healthy omega-3s. They pair beautifully with banana and help balance the soft texture of the oats with a satisfying bite.
Honey or Maple Syrup (optional):
If you prefer a sweeter breakfast, a small drizzle adds warmth and depth. Both blend easily into the mixture and enhance the banana flavor without overpowering it.
Vanilla Extract:
Just a small splash elevates everything, giving the oats a subtle, comforting aroma and making the overall flavor feel more rounded.
Cinnamon:
A pinch of cinnamon ties the whole recipe together. Its warm, cozy flavor complements banana and walnut perfectly.
Ingredients List
- 1 cup old-fashioned rolled oats

How to Make Banana Walnut Overnight Oats
Mix the Dry Ingredients
In a jar or container, combine the rolled oats, chia seeds, walnuts, and cinnamon. Give everything a quick stir to evenly distribute the ingredients.
Add the Wet Ingredients
Add the mashed banana, milk, vanilla, and honey or maple syrup if using. Stir thoroughly until all ingredients are well incorporated and no dry oats remain.
Seal and Refrigerate
Close the jar with a lid and place it in the refrigerator overnight or for at least 4 hours. This resting time allows the oats to absorb the liquid and soften.
Serve and Enjoy
The next morning, give your oats a quick stir. Add extra banana slices, more walnuts, or a drizzle of honey if you’d like. Enjoy straight from the jar or pour into a bowl.
Tips for Making This Recipe
- Use very ripe bananas if you want more natural sweetness.
- For thicker oats, add extra chia seeds or reduce the milk slightly.
- For a creamier texture, mix in 2–3 tablespoons of yogurt before refrigerating.
- Prep multiple jars at once for easy grab-and-go breakfasts during the week.
- Add toppings right before eating to keep nuts crunchy and fruit fresh.
- Swap walnuts for pecans, almonds, or a mix of nuts if you prefer.
FAQs
Can I use quick oats instead of rolled oats?
Yes, but the texture will be much softer. Rolled oats give the best result.
How long do overnight oats last in the fridge?
They’re best within 2–3 days, but can last up to 4 days if stored in an airtight container.
Can I make this recipe vegan?
Absolutely—just use plant-based milk and skip honey or replace it with maple syrup.
Can I warm up overnight oats?
Yes. Heat them in the microwave for 30–60 seconds, adding a splash of milk if needed.
Can I add protein powder?
Yes. Add 1 scoop and slightly increase the milk to keep the mixture from becoming too thick.
