Peanut butter banana overnight oats are rich, creamy, and seriously filling with more than 26 grams of protein and 13 grams of fiber. As a registered dietitian and busy mom, I don't have time for hunger mid-morning, and these overnight oats always keep me full until lunch!
My overnight oat obsession started when the morning just kept getting away from me. Skipping breakfast means I'm starving, tired, and looking for snacks all morning long. These banana peanut butter overnight oats are super rich and satisfying, while adding 26 grams of protein and 13 grams of fiber to your morning (plus more if you drizzle peanut butter on top!).
It's sweet enough to feel like a treat, without relying on too much added sugar. Just a couple of teaspoons of honey and mashed banana give this oatmeal a banana bread-like sweetness. Plus, it only takes 5 minutes to mix together the night before, and you wake up to breakfast, ready to go!
If you love creamy, satisfying breakfast combinations, you'll want to add my banana pudding overnight oats or chocolate peanut butter overnight oats to your meal prep breakfast rotation!

Why You'll Love This Recipe
- Two minutes of prep the night before means zero effort in the morning

- 26 grams of protein and 13 grams of fiber to keep you full all morning
- Kid-friendly and easy to customize with whatever toppings you have on hand
- No cooking, blending, or special equipment needed!
Ingredients
- Greek yogurt - Use plain, nonfat Greek yogurt. It blends in smoothly and adds a big protein boost without changing the flavor. This is one of my favorite ingredients to work into breakfast because it does so much without you even noticing it.
- Banana - The riper, the better. A spotty banana is sweeter and mashes more easily, which means you get better banana flavor throughout every bite. Cut it in half and save the other half for slicing on top in the morning!
- Peanut butter - One tablespoon goes into the mix, but don't skip a little drizzle on top! It makes the whole thing feel more special and adds a little extra healthy fat to keep you satisfied.
- Chia seeds - These little guys thicken the oats overnight and sneak in extra fiber and omega-3s. You won't even notice they're there texturally, but your body will. I use chia seeds in a lot of my make-ahead breakfasts, like my blueberry chia seed pudding, for exactly that reason.
Topping Ideas
Don't forget the toppings! You can totally change up the flavor and make these oats absolutely irresistible depending on what you drizzle, sprinkle, or slice on top! Here are some favorites:
- Fresh banana slices
- A drizzle of peanut butter
- Crushed peanuts or granola for crunch
- A sprinkle of cinnamon
- Mini chocolate chips if you're feeling it
- Sliced strawberries for a little brightness
How to make banana peanut butter overnight oats
Add all your ingredients to a jar or container with a lid, give everything a good stir, and pop it in the fridge. That's it.
In the morning, give it another stir, add your toppings, and eat it cold straight from the jar - or let it sit on the counter for a few minutes (or even microwave it) if you prefer it less chilly.
If you're someone who likes having a few breakfasts ready to go, you can make a double batch and keep them in the fridge for up to two days. This is one of my favorite benefits of overnight oats: A healthy breakfast you can literally grab and go in the morning!

Equipment
To store these overnight oats for ready-to-grab single servings, I like to make them in 16-ounce overnight oat containers, but any 2-cup dish with a lid will work!
Top Tips
Use a ripe banana. A ripe banana will mash easily and add more natural sweetness to these oats. If your banana is too green, you may notice the oats are more bitter than you'd like.
Mash the banana well. The more thoroughly you mash it, the more evenly the banana flavor and sweetness distribute through the oats.
Let it sit at least 4 hours. The oats need time to soak and soften. Overnight is easiest, but even a full afternoon works if you're prepping for dinner-time snacking or a late breakfast.
Adjust the consistency. If you like thicker oats, reduce the milk slightly. If you prefer them looser, add a splash more in the morning.
Storage
Store your peanut butter banana overnight oats in a sealed jar or container in the refrigerator for up to 2 days. Keep the toppings separate until you're ready to eat so nothing gets soggy. If you keep these for more than two days, the banana will start to go bad and give the oats an obvious "off" flavor.
I wouldn't recommend freezing these - the texture of the banana and yogurt doesn't hold up well once thawed.
Trouble Shooting
The oats are too tough: You may not have added enough milk or you may not have let the oats sit long enough. If they're too dense, thick, or the oats seem too chewy, just add more milk or let the mixture sit longer in the refrigerator.
I don't like chia seeds: If you don't like chia seeds. Try one of my overnight oat recipes without chia seeds, like chocolate peanut butter overnight oats, or just swap for an equal amount of flaxseed or leave the chia out completely. The protein and fiber will be lower if you leave it out, though!
FAQ
Yes! Almond butter or cashew butter both work great here. Sunflower seed butter is a good option if you're avoiding peanuts.
You can, but thaw it first and drain any extra liquid before mashing. Frozen banana can make the mixture a little watery if you skip that step, and tends to go "off" more quickly than fresh, so you may want to eat it within 24 hours.
Swap the Greek yogurt for a dairy-free yogurt alternative and use a non-dairy milk. It will be a little lower in protein, but still a solid breakfast.
Nope. If you'd rather have a warm breakfast, scoop it into a bowl and microwave it for 60 to 90 seconds, stirring halfway through. The texture changes a bit, but it's still really good.
Absolutely. A scoop of vanilla protein powder blends in well and bumps the protein even higher. You may want to add a splash more milk since protein powder tends to thicken things up. My chocolate protein overnight oats use the same approach if you want inspo.
