This no-fuss banana bread overnight oats turns your breakfast into something special without much work. The smooth oats mixed with sweet banana brings that familiar banana bread taste to your morning meal – all while sitting in a jar that's waiting for you when you get up.
I first whipped these overnight oats up during those super hectic weeks when I couldn't make breakfast in the morning. Now my kids ask for them all the time, particularly when we've got bananas getting too ripe on the kitchen counter.
What You'll Need
- Banana: your key ingredient that brings natural sweetness and that true banana bread flavor profile
- Rolled oats: go for the thicker old fashioned kind instead of quick oats for a better mouthfeel
- Milk: gives you that dreamy creaminess as it works into the oats while you sleep
- Walnuts: add good fats and that nice crunch you'd expect in regular banana bread
- Maple syrup: brings just enough natural sweetness that works magic with banana
- Vanilla extract: makes everything taste like dessert without extra sugar
- Cinnamon: adds that cozy warmth you can't have banana bread without
- Nutmeg: just a tiny bit creates amazing flavor background notes
- Kosher salt: cuts through sweetness and makes all other flavors pop
How To Make It
- Squish Your Banana:
- Get a medium-sized banana and smash it up with a fork until it's mostly smooth but still has some tiny chunks for texture. Put this mashed banana at the bottom of your container to start a tasty foundation.
- Mix Everything Together:
- Drop in your oats, milk, chopped walnuts, maple syrup, vanilla, cinnamon, nutmeg, and salt right on top of that banana. Mix it all up really well so there aren't any dry oat spots hiding anywhere.
- Let It Sit Overnight:
- Put the lid on tight and stick it in your fridge for at least 6 to 8 hours, but overnight works best. This waiting time lets the oats get soft and soak up all the banana and spice flavors, creating that magic banana bread taste.
- Finish And Eat:
- When morning comes, give everything a good stir. Add some fresh banana slices on top and maybe a little extra maple syrup if you want. You can eat it cold right from the fridge or warm it up for 30 to 60 seconds if you like a warm breakfast instead.

The maple syrup is my hidden gem that takes these oats from just okay to absolutely amazing. I found out how important it was when I ran out one day and used honey instead. Still tasted good, but maple syrup brings this warm sweetness that fits perfectly with banana and really makes these oats taste like actual banana bread.
Make-Ahead Wonder
You can easily make several jars of these oats at once for grab-and-go breakfasts all week. Just multiply everything and fill up multiple containers. They'll stay good in your fridge for about 4 days, so it's perfect for Sunday prep when you know weekday mornings will be crazy. The flavors actually get even better after sitting for a day.
Diet-Friendly Swaps
You can tweak this recipe for pretty much any diet without losing what makes it so good. If you can't do dairy, just swap in some almond milk, oat milk, or coconut milk instead. Each one adds its own nice flavor twist alongside the banana. Need it gluten-free? Just make sure you buy oats labeled as certified gluten-free. For vegans, use any plant milk and double-check your maple syrup is pure.
Mix It Up Your Way
What's great about overnight oats is how you can change them to fit what you like. Try throwing in a spoon of chia seeds for extra healthy fats and a thicker texture. Want more protein? Stir in some peanut butter or almond butter before it goes in the fridge. If you love chocolate, add some cocoa powder or a few chocolate chips. For something fresh, toss in berries right before eating to play off the banana flavor.
