🧡 Why You'll Love This Recipe

Hey friend. Whether it's in the form of my peanut butter smoothie recipe, banana sushi, or these peanut butter banana overnight oats, you just cannot beat the classic PB and banana combo!
Here's why you'll love this recipe:
- Make Ahead: Prep a batch of these overnight oats in literally 5 minutes
- Packed Full of Protein & Fiber: A full batch has 28g of protein and 12g of fiber without any added protein powder or fiber.
- So Easy To Make: If you can stir, you can make these.
- A recipe you can trust: My healthy overnight oats recipes have been viral on the internet for over a decade. With thousands of 5 star reviews, you can trust my oats recipes.
🍌 The Ingredients You Need

- Oats: I recommend rolled oats here. Quick cooking or steel cut oats won't have the same texture (but they are great in my slow cooker steel cut oats recipe).
- Ripe banana: Use a banana with a few spots on it so it gives lots of sweetness needed to flavor these oats.
- Peanut butter: I like natural peanut butter because you can control the sweetness, but honestly, use whatever you have on hand!
- Greek Yogurt: any plain Greek yogurt will do, or you can use homemade yogurt, just make sure to strain it first (here's the yogurt strainer I use every week)
- Chia seeds: help them thicken up the oats as well as add protein and fiber, you can also swap in equal amounts of flax meal
- Honey or maple syrup: I prefer the flavor of maple syrup in these oats, but either option works-or leave out the sweetener all together if you want to cut back on sugar.
Make sure to check the recipe card below for the full ingredients list, along with quantities and my expert tips and tricks.
🔁 Variations & Substitutions
- Make it vegan: Use maple syrup, plant-based milk (almond milk or oatmilk work great) and vegan Greek yogurt
- Make it gluten-free: These oats are naturally gluten-free as long as you choose certified gluten-free oats.
- No chia seeds? Swap in equal amounts of ground flax.
- Up the protein: Add a scoop of vanilla or unflavored protein powder!
- Make it sugar-free: Drop the sweetener and add an extra ½ mashed ripe banana. Or use stevia or monk fruit sweetener in place of the maple syrup or honey if you prefer.
- Add chocolate: Follow my banana chocolate chip overnight oats recipe if you'd like a boost of chocolate and banana flavor in your oats!

🙋🏻♀️ Peanut Butter Banana Overnight Oats FAQs
Yes! Peanut butter adds flavor, richness, and creaminess to overnight oats, plus it's a tasty way to boost protein in oats.
Sure can! You can either put mashed bananas in overnight oats or chopped bananas, just make sure if you use chopped bananas, all the pieces are buried in the oats to prevent browning from oxidation.
👩🏻🍳 My Expert Tips & Tricks
- Make lots: doubling or tripling this recipe takes no extra time but gives you lots of extra breakfasts-perfect for big families!
- Boost the nutrition: add in protein powder, collagen powder, fiber supplements, oh my!
- Customize your toppings: Try cocoa powder, cacao nibs, chocolate chips, chopped peanuts or walnuts.
- Wait at least 4 hours: yes these are called "overnight" oats, but you can get away with eating them after at least 4 hours in the fridge
- Sweeten to taste: some people like breakfast foods sweeter than others, so start with a small amount of maple syrup or honey, taste your oats, then add more if you like.

Is there a more classic combo than peanut butter and banana? I think not! This flavor of overnight oats is my kiddo's favorite, and she requests it almost every week! Sometimes I add in a scoop or two of whey protein isolate to bump up the protein. Either way, it's delicious every time! Enjoy.
How long will these overnight oats keep in the fridge ?
Hi CJ! We typically make these on the weekend to eat throughout the week. So you should be good to stash them in the fridge for 5 days up to a week or so. =)
