For as long as I remember, I’ve been OBSESSED with oatmeal. In college, I’d eat oatmeal every single morning with sliced bananas and drizzle of peanut butter on top — and yes you guessed it, a healthy dose of breakfast nostalgia is exactly what inspired these incredible overnight oats.
These peanut butter banana overnight oats are creamy, packed with 15g of protein thanks to siggi’s + peanut butter, and perfect for both kids and adults. Bonus, there’s absolutely no cooking required. Just stir everything together the night before and then get ready for bites of banana bread inspired heaven in the morning.
What are overnight oats?
Overnight oats are simply oats soaked in a liquid overnight until they expand and ‘cook.’ In this recipe, the oats soak up the milk and yogurt to create the creamiest texture. The banana adds a natural boost of sweetness, too! There’s no real “cooking” or heating required, so overnight oats make the perfect breakfast on hot summer days.
Mornings made better with overnight oats
Not only do these peanut butter banana overnight oats taste amazing, but they’re also packing the nutrition to keep you full and satisfied after breakfast. These overnight oats:
- Pack in healthy fats: from creamy peanut butter and chia seeds.
- Have over 15g of protein: thanks to siggi’s yogurt and peanut butter.
- Are naturally sweetened & gluten free: just use gluten free rolled oats and a ripe banana!
- Take just 10 minutes to prep: for an easy, nourishing breakfast you can enjoy on-the-go the next day!
Everything you’ll need to make peanut butter banana overnight oats
These protein-packed peanut butter banana overnight oats couldn’t be easier to make with such delicious, simple ingredients. Here’s everything you’ll need to make them:
- Banana: you’ll mix the overnight oats mixture with mashed ripe banana for that yummy banana bread flavor and natural sweetness.
- Milk: feel free to use any milk you’d like. I prefer almond milk.
- siggi’s Yogurt: I love adding siggi’s Vanilla Yogurt for a little extra flavor, but plain works just as well. The yogurt adds the perfect boost of protein while making the peanut butter overnight oats super creamy and delicious.
- Oats: we’re using rolled oats to keep a creamy texture. Be sure to use a gluten free brand if you need to keep the overnight oats gluten free.
- Cinnamon: a little flavor booster to really bring out that banana bread flavor. YUM.
- Chia seeds: just a tablespoon of chia seeds adds healthy fats, fiber and protein. Plus they thicken up the overnight oats for a wonderful texture.
- Peanut butter: gotta love a little peanut butter mixed right in and drizzled in the layers (if you’d like). Win-win for extra healthy fats.
Make these peanut butter overnight oats your own
Looking to customize? So easy! Here are some ways you can jazz up these peanut butter banana overnight oats:
- Add extra fruit: these overnight oats would be delicious with sliced strawberries, blueberries or raspberries for a little PB&J flavor.
- Choose your nut butter: while the peanut butter gives these overnight oats such a delicious flavor, you can also use almond butter, cashew butter or sunflower seed butter. If you wanna get crazy, use chocolate almond butter/peanut butter.
- Have fun with siggi’s flavors: while I love using their vanilla variety in this recipe, I think any of their berry flavors or even coconut would be amazing in here.
- Go (coco)nuts: try using light coconut milk and even adding some unsweetened shredded coconut for extra creaminess and delicious flavor.
- Toppings = love: don’t forget to top with extra banana slices, a drizzle of peanut butter and maybe my homemade granola recipe! Also, mini chocolate chips, anyone?
Nutrition boosters we love
Feel free to add even more nutritional boosters to these peanut butter banana overnight oats like:

- Mix the wet ingredients. Add your mashed banana, milk and siggi’s yogurt to a bowl and mix well until nice and creamy.
- Stir in the dry. Fold in the rolled oats, cinnamon & chia seeds, then cover the bowl and place it in the fridge for at least 4 hours. Overnight works super well, too!
- Serve them up. Divide everything between two bowls or mason jars and layer with extra banana slices and peanut butter if you’d like. Top with anything your heart desires and enjoy!
Can you eat them warm?
If you’re not a fan of cold overnight oats, they’re actually delicious warmed up, too. Just heat them in a bowl in the microwave for a minute or two before enjoying. Be sure to give them a good stir and feel free to add more almond milk if you’d like.
Storing tips
This healthy peanut butter banana overnight oats recipe will stay good in the refrigerator in an airtight container or mason jars for up to 5 days. This makes them portable and easy to enjoy on-the-go during busy weekdays. Just be sure to give them a good stir if they’ve been sitting for a couple of days and/or add another splash of almond milk.

sooo good! i love the high protein content 🙂 will make again
So glad you enjoyed!
Hi there – this was a bit ‘soupy’ for me after sitting overnight! I added more oats and was ok, but I’d adjust the ratios a bit going forward!
Hi! Hmm very strange – what type of yogurt did you use?
This is my go-to recipe for overnight oats. By which I mean it’s nearly the only one I’ve ever made. I only started making (or eating!) oats regularly in the past couple of years and it’s in the fridge pretty consistently, often in a double batch.
I’ve made it with frozen/thawed banana a couple times. When they were whole, I let them thaw. When they were sliced, I mixed everything except the oats and chia in a blender. I mash the banana with a fork and didn’t like the idea of mashing individual slices when it’s usually all one piece.
I don’t usually use a whisk to mix this, so I used to get little chunks of peanut butter in the final oats… which is honestly pretty fun. Even so, I’ve played with the mixing order. Now I usually mix the banana and the peanut butter together first, then maybe cinnamon (not always) and go from there.
It goes in the fridge, and I serve myself straight from the mixing bowl for the rest of the week or so. Tried and true, for sure.
Love that! These are great for customizing 🙂 So happy they’re a favorite!
Good recipe, but this is definitely not a “high protein” recipe. 400kcals and 19g of protein? That’s not good.
Only add 1TBSP of peanut butter, use FairLife fat free milk instead of almond milk, use Greek fat free yogurt, and add 1 scoop of vanilla or chocolate whey isolate protein powder.
I find 19g of protein to be “high” compared to a ton of other recipes, especially overnight oats!
So yummy!! I added strawberries to the mix and then did crunchy peanut butter for more texture 🙂 Makes a perfect meal prep breakfast
Love that!!
I doubled this recipe and used Fairlife milk for a little more protein and it’s delicious! So easy to grab a bowl before work, and it’s so tasty and filling! Will definitely make again.
I might try adding chocolate protein powder to it in the future!
Such a great weekday breakfast! Love the idea of adding chocolate protein powder 🙂
I’d like to try these overnight oats but, how do you think of steel cut oats instead of rolled oats?
Do you use quick or regular rolled oats? I would imagine not steel-cut? Thanks.
Regular rolled oats work best!
Thank you. And, the recipe is delicious. Great summer recipe and I just made them for a second time this week. Going to try hemp seeds on top (just before serving) next time.
Hello! This recipe looks amazing. Please could you tell me how many grams/millilitres would be in one of your cup measures? I want to make sure I get it right! Thank you so much 🙂
Hi Emily – I am working on adding that to my blog, but in the meantime I would recommend using an online converter. So sorry!
These look so good! Could I ask, how many grams/millilitres would be in one of your cup measures please? I want to make sure I get the balance of the recipe right! Thank you 🙂
Love this recipe, I use blender for all ingredients except oats then combine after with some crushed walnuts on top, thanks for sharing, third or 4th time in a row I’ve made them for breakfast meal prep.
Yum! So glad you are enjoying these OO, Jacob. Glad you are able to make these to your preference!
I’ve made this a few times and love that I can get two or three breakfasts out of it. I usually add some berries or extra fruit and it fills me up and tastes great. Thanks for sharing!
Aw yay! I am so glad you are enjoying this recipe 🙂
I absolutely love these oats and eat them at least twice a week now (sometimes more!). I sometimes substitute other yogurts based on what I have and it’s still so good! I make mine with soy milk and always add extra cinnamon because cinnamon makes everything even better to me. Definitely worth making and easy to exchange ingredients for whatever you have available or whatever you happen to be craving.
Perfect! So glad this one’s a favorite!
I had never fixed overnight oats, but I became willing to try when I saw banana and peanut butter as ingredients. I have now made this recipe several times and have shared it with friends and family. I don’t use Almond milk, I switch out between regular 1% or 2% milk. I have used all brands of yogurt, depending on availability, but have always stuck with the vanilla flavor.
So happy you love these!! Thanks, Jennifer 🙂
My new favorite!
I’m so glad!! Thank you!
This is my go-to breakfast. I love that it’s naturally sweet, high in protein, very filling and nutritious! Perfect for meal prepping
I’m so glad you love it!!
So yummy. Made this tonight and tasted it and it was yummy. I added honey! I can’t wait to try it in the morning. Yum !
I’m so glad you enjoyed it, Ann!
I’ve made this recipe three times this week because it is so delicious! I half the recipe for a single serving and used Kefir instead of Siggi’s yogurt. It’s my new breakfast favorite!
Curious if you are to add peanut butter the night before with oats.
It does not say that in the recipe. Is it only added the next morning?
Hi, Christine! Great question and thanks for noticing that! We meant to include peanut butter in step 1, meaning YES you do mix it into the oats. We’ll update that 🙂 And I also like to add some on top/between the layers for extra flavor.
This was DELICIOUS!! Even my kids loved it! Another perfect recipe from Ambitious Kitchen!!
This was very good!! I made it exactly as listed but I put the ingredients directly into the mason jars. Put half in each jar. This made it easier to grab and go in the morning. I had never added yogurt to our overnight oats and it does make it creamier! So good!!! Thank you!
Nice! So glad you loved this recipe, Rose. Thank you!
Made weekday breakfast so much easier and so much tastier!!! so dang creamy and delicious, peanut butter anything is a favorite of mind!!
❤️ Thanks, Casey!! Couldn’t agree more that PB is THE BEST.
This overnight oats recipe tastes so good and is so easy to make! It’s saved me many mornings, and it’s one that I always fall back on.
Oh yay!! Glad to hear you’re loving this one 🙂
LOVE these overnight oats!! I made them while nursing and added in Brewer’s Yeast and Flaxseed to boast my milk production. They are so easy to make ahead. I always made a double batch. Thank you!!
Awesome! Such a great idea to add flax and brewer’s yeast. Thanks for sharing! 🙂
I love this one. It’s kind of a no brainer if you love bananas and pbutter like I do. It’s perfect to make a head and it’s two servings. Definitely a must try!
Cannot say enough good stuff about this recipe! As a new mama, I am constantly looking for something easy, delicious and filling. I have made this every other week at this point! Sometimes I use a little almond/coconut milk if I’m feeling fancy aka if it’s in the fridge(Highly recommend making the triple berry bake from ABK also, my other breakfast staple!)
Aw thank you so much for the rating!! Glad to hear you’re loving this one (and the baked oatmeal!) 🙂
These are great for breakfast! So tasty
Yay! I’m so happy you’re enjoying them, Jess!
These oats are so creamy & I love that you don’t add the peanut butter until you are ready to eat them!
I’m so happy you’re loving them, Katie! 🙂
I didn’t think I would enjoy overnight oats but this recipe made me fall in love with it. Such a perfect recipe for a healthy breakfast!
That’s amazing! I’m so glad to hear it 🙂
I loved these overnight oats!! I’ve been making the same type for a few weeks and came across this recipe recently and had to try it! SO good! Go make this ASAP!
I’m so happy to hear that, Lisa! Yay! 🙂
I made this recipe exactly as written and it’s delicious! Yummy & easy breakfast. I made 3 servings instead of 2 and topped it with berries. Will definitely make again.
So happy to hear that, Deborah! Great idea to top with berries–yummm 🙂
I make this Oatmeal with Almond Butter, Almond Milk & Blueberries
I have not thought of adding a yogurt
I love the added protein and creaminess that yogurt gives! Hope you can try it soon 🙂
Would love to make this
Hope you can try it soon! 🙂
