🍌 The Ingredients You Need

Ingredients for peanut butter banana overnight oats on a countertop
  • 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

Is peanut butter good in overnight oats?

Yes! Peanut butter adds flavor, richness, and creaminess to overnight oats, plus it's a tasty way to boost protein in oats.

Can you put bananas in overnight 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.

    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.

    1. 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. =)
