About these Oats
Have you ever tried the pre-packaged overnight oats from Mush? This homemade Banana Peanut Butter Overnight Oats recipe reminds me of them—but without the extra sugar! And that peanut butter + banana combo is soooooo stinkin’ delicious!
Overnight oat recipes went viral in the pandemic and I think we were all just experimenting with ways we could eat the same foods, but differently? Especially with unusual free-time/down time on our hands?
I first made this banana overnight oats recipe during Covid, but gave it a face lift. You’ll love because they’re high in protein, take less than 5 minutes to make, and will become a staple part of your breakfast routine. I love that I can make the oatmeal the night before and grab them on a busy morning or even enjoy them as a snack or for lunch or dessert! Plus, you probably have everything you need in your pantry to make them already. 😜

Recipe Inspo
I’ve developed a variety of high-protein, overnight oats recipes and they make for wonderful, make-ahead breakfasts! I love having some prepped in the refrigerator for after a workout/long run. This recipe is no exception as it pairs two of the best flavors together: peanut butter and banana. Heck, add in chocolate and you’ve got yourself a chunky monkey breakfast recipe!
Recipe Ingredients

- Oats: I used old fashioned rolled oats. They soak up all the flavor so well! Quick Oats will get too mushy and steel cut will not soften much.
- Yogurt: Adds such a great creamy texture and some protein. I used Two Good Vanilla yogurt, but you could also use a plain Greek yogurt, too.
- Peanut Butter: I like creamy peanut butter to create the magic shell, but if crunchy is your thing, that works too.
- Milk: I like 2% or Fairlife for extra protein. A dairy free alternative is also sufficient.
- Chia Seeds: Get in your fiber! I also like how these get a little jelly-like as they sit in the liquid and firm up.
- Banana: I recommend using a spotty one so it really sweetens these oats up.

Substitutions and Variations
I have so may overnight oat recipes you should check out if you want to shake things up. Carrot Cake Overnight Oats, Pecan Pie Overnight Oats and Almond Joy Overnight Oats might be my fav, but if you want to modify this recipe, feel free! Some options:
- Nut butter: Use cashew butter or almond butter instead of peanut butter or try granola butter or a seed butter to make it nut free.
- Fruit: Add additional fruit like diced apples or berries. Or use chopped strawberries instead and make these peanut butter & jelly overnight oats. Love that flavor combination? Try my Peanut Butter and Jelly Cups or these PB&J Bars.
- Toppings: So many possibilities for your favorite toppings. Additional nut butter, sliced bananas, chopped peanuts or another nut, chia seeds, hemp seeds, pumpkin seeds. Add a drizzle of maple syrup for more sweetness or a dollop of greek yogurt or whipped cream for extra creaminess.
How to Make This Recipe
1. Decide whether you’re going to prep this recipe in portion size tupperware/a mason jar or in one big batch. If using multiple containers, divide this recipe by two or four to ensure equal proportions.

1. Pour the rolled oats, yogurt, almond milk, and protein powder into a mason jar or small Pyrex bowl.

2. Once mashed, pour the rest of the ingredients (except the peanut butter) into the bowl.

3. Stir together so the oats are covered. Pending time allows, refrigerate the oats for 2-4 hours before adding the hard-shell peanut butter topping. If not, simply stir the peanut butter into the oat mixture before placing in the refrigerator.

4. Before serving, melt the peanut butter in a microwavable safe bowl for 30 seconds. Pour onto the top of the overnight oats and allow to harden (to create that “magic shell” top!)
PRO TIPS
- Use creamy peanut butter (not the naturally ground kind) for that smooth, hardshell top.
- Rolled or quick oats are best suited for overnight oats. Steel-cut oats need a much different liquid-oat ratio and I wouldn’t recommend a quick swap here!
Recipe FAQs
Store your peanut butter banana oats in the refrigerator. They’re best enjoyed within 3 days, making them a great option for meal prep! Much longer, however, they’ll become pretty mushy.
I recommend using a ripe banana to bring as much sweetness as possible to your oats! If yours are still kind of green, don’t worry. Here are some tips on how to quickly ripen your bananas:
If you have a day or two before you’re planning to bake, put your bananas in a brown paper bag overnight. Bananas naturally release ethylene as they ripen. The bag traps the ethylene, allowing the ripening process to happen faster. Adding an apple, pear, or avocado to the bag will also speed up the ripening process.
If you need to ripen your bananas ASAP, you can also use your oven! Preheat to 350°F and bake your bananas with the peel on for 20-30ish minutes until they’re browned and soft. Allow your bananas to cool in the fridge before peeling and using them in this recipe.
I’ve always eaten them cold, but they can absolutely be warmed. Keep in mind that you may need to also add more milk for creaminess if you heat them in the microwave or on the stovetop.
Blended overnight oats also had a viral moment (has everything at this point?!) They’re perfect if you want a smooth and creamy overnight oats recipe. Simply blend everything together, transfer them to the tupperware of choice, refrigerate, and pour the melted magic shell creamy peanut butter on top before enjoying – that simple!
