If I had to choose one overnight oats flavor to eat for the rest of my life, it would hands down be this peanut butter banana variation. I can’t even count the amount of times I’ve made them and the same goes for lots of you. I love eating them with a giant scoop of peanut butter on top with some sliced bananas. And, more recently, I’ve been adding a scoop of protein powder!

Variations for PB Banana Overnight Oats
- Add protein: If you’re hoping to fit more protein into your diet, go ahead and try adding around 2 tablespoons of your favorite protein powder or collagen.
- Use a different sweetener: feel free to swap the honey for maple syrup, agave, or even brown sugar.
- Swap the peanut butter: if you can’t do peanut butter, any kind of nut butter works. Try almond butter or cashew butter!
Topping Ideas
Don’t forget the toppings…it’s the best part! We went with more sliced bananas, a dollop of creamy peanut butter, and some chopped peanuts. Here are other ideas:
- Berries
- chocolate chips
- Fresh lemon zest

I tried making these overnight oats, and they turned out amazing! Super easy to whip up and perfect for a quick breakfast. The peanut butter and banana combo is really good. The only thing is that my version turned out to be more calorie-dense, but it’s still super healthy. I’ll definitely try making this dish again! Also I wanted to ask is whether it’s worth wrapping the dish in plastic wrap when storing it in the fridge, or if it will be fine without it?
I would cover the dish when you store it in the fridge!
These overnight oats were really delicious. This was my first time trying them again. I tried them once and I just didn’t really like them. But now I’m a believer because of this recipe. It really did make a lot and I definitely got two meals out of this recipe.
Yum!
I’m new to overnight oats, haven’t tried them with a banana yet but this sounds delicious! My question is: will the banana keep well overnight if I don’t cover it? I only make it for the next morning, and don’t have much equipment in my student kitchen.
