It’s not *quite* blueberry season yet, but with the warmer winter we’ve had I’m already dreaming about all of the fresh summer berries. There’s nothing more I love than popping juicy little blueberries like how I used to pop Sour Patch kids back in middle school. In fact, I ate so many Sour Patch Kids in one day that my tongue literally peeled off.
Safe to say that I’m happy I’m over my middle school candy obsession. I’ll stick with the spring & summertime sweet blueberries, especially in these incredible peanut butter blueberry overnight oats.
I first published this overnight oats recipe back in 2018 and they’re still one of the most popular ones on the blog. For good reason! Creamy, protein-packed overnight oats layered with sweet blueberry jam and peanut butter? What more could you need?!
What makes overnight oats healthy?
What I like about these overnight oats is simple: they’re packed with protein thanks to yogurt, there’s no added sugar, healthy fats thanks to peanut butter making these overnight oats a great healthy breakfast option. Bonus: they taste like a peanut butter and jelly sandwich!
Ingredients in peanut butter blueberry overnight oats
This protein-packed blueberry overnight oats recipe is basically a fancy version of a PB&J for breakfast. Here’s what you’ll need to make them:
- Yogurt: feel free to use any yogurt flavor you’d like, but I do recommend using vanilla, coconut, or blueberry. The yogurt adds the perfect boost of protein. Dairy free yogurt would also work!
- Almond milk: or any milk will work in this recipe.
- Chia seeds: these add healthy fats & fiber to the blueberry overnight oats recipe while also helping to thicken them a bit for the perfect texture.
- Rolled oats: feel free to use gluten free rolled oats but I wouldn’t recommend steel cut oats as the texture will be different. I find that rolled oats are the best to use for overnight oats recipes.
- Fresh blueberries: these oats are delicious with fresh blueberries mixed right in and then added on top when you’re ready to enjoy! You can also use frozen blueberries if you’d like.
- Low sugar blueberry jam: or any jam flavor you’d like for the delicious layer in the middle.
- Peanut butter: I always use an all natural, creamy peanut butter in the middle layer that’s made with just peanuts and salt. You can use any nut butter you’d like in here, and even try a crunchy peanut butter. YUM.
Can I use steel cut oats?
Unfortunately, no, I cannot recommend using steel cut oats because they will not absorb as much liquid as rolled oats so the texture will not turn out right.
Make these overnight oats your own
Feel free to get creative with this recipe! Here are some swaps I can recommend:
- Choose your yogurt. As I mentioned, you can feel free to use any flavor of yogurt you want — even dairy free! I think vanilla, blueberry or coconut yogurt would be perfect in this recipe.
- Pick your nut butter. I’m a sucker for all things PB&J, but you could also add almond butter, cashew butter, or, to keep them nut free, sunflower seed butter.
- Try a new berry. Raspberries, strawberries, and different berry jams would also be delicious in here!
How to make creamy peanut butter blueberry overnight oats
- Mix the liquids. Start by stirring the yogurt and almond milk together until smooth.
- Add the dry. Mix in the oats and chia seeds. You could also customize your overnight oats by adding blueberries or even a tablespoon of hemp seeds or flax for an extra boost of nutrition.
- Refrigerate the oats. Cover the bowl and place it in the refrigerator for at least 3 hours or, ideally, overnight so that the oats thicken.
- Assemble the jars & enjoy! After they’ve been in the fridge they should reach the consistency of regular oatmeal, but will just be cold! You’ll then add the oat + yogurt mixture to two jars, top with blueberry jam and peanut butter, and then finish it off with the rest of the oat + yogurt mixture.
How to store overnight oats
The great part about this easy blueberry overnight oats recipe is that they’ll stay good in the refrigerator in an airtight container or mason jar for up to 5 days. This makes them super 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.
Can you eat overnight oats warm?
The answer is: yes! I love enjoying this peanut butter blueberry overnight oats recipe cold, but if you prefer your oats warm you can feel free to heat them up in the microwave before eating them. Give them a good stir after heating them, too, so that the consistency remains the same.

These oats are my go-to whenever I’m craving PB&J! I use regular Greek yogurt with a splash of vanilla & maple syrup to sweeten it & also add a scoop of vanilla protein powder – so good & keeps me full for hours!
Love it! Perfect breakfast!
This was so yummy and i love how high protein it is, i didnt really feel like layering the jam and peanut butter so i just simply mixed it in, was still super good, tastes like a pb and j!
Perfect breakfast!
This was so delicious, i did a scoop of collagen in it for more protein, coconut yogurt and i didnt bother layering just mixed it all together hahaha but this will definitely be on repeat!!
Love that!
So yummy! Great flavor and texture and super easy to make!
So happy you enjoyed it, Jenny!!
Wow, this was great!
I like your recipes
I’m so glad!
I’ve been making this since last summer and it’s my ultimate go-to summer breakfast. Love the PB&J combo and it’s perfect on the go breakfast for my boyfriend who goes to the office every day. Quick question though: if I have a large container of Greek yogurt leftover, how much of it should I use for this recipe – would 1/2 cup be sufficient?
Love this recipe! Make some variant of this a few days a week for breakfast. Tastes great and keeps me full. Highly recommend!
I’m so happy you’re a fan, Julie!
Of course a 5/5 🙂
My new fav overnight oats recipe!! I have been making overnight oats for a while, but this combo of sweet jam and globs of PB is a def winner. I did fresh strawberries instead of blueberries because I was out and it still tasted amazing. I was worried the oat base itself wouldn’t be sweet enough, but using if vanilla Greek yogurt makes is perfect. Definitely going to be making this one for more school mornings!
Super filling and easy!
Could I use dairy milk instead of almond milk if that’s what I have on hand?
Absolutely, that’ll work well!
This recipe was amazing. It was my first time making overnight oats, and it definitely will not be my last! Yum!!
Yay!! So happy you loved them, Michelle. Can’t wait for you to make them again 🙂
I used to make this a few years ago regularly, and just had to make them again when i saw the new Siggis (lower sugar?) at the store! So good. Will be back on the regular rotation again. 🙂
Yes – love it! One of our fav breakfasts, too 🙂
This is the best overnight oat “base” recipe. Creamy, great flavor, filling. I make this recipe often, but I always use it as my base for other toppings.
Love that! Perfect for customizing 🙂
Could I use dairy milk if that’s what we have in the house?
This recipe is a constant staple in my fridge. The flavors are everything you want in overnight oats. The sweet and salty duo of Pb and j is incredible.
Love that! Perfect breakfast 🙂
These are the best overnight oats I’ve ever had! I use a vegan yogurt for dairy free and frozen blueberries, they thaw by morning!
So glad you loved them!
The combination of blueberries and peanut butter in these overnight oats is amazing! The combination of all of the ingredients makes for a great texture as well.
So delicious! Glad you loved it!
I was skeptical of the over night oat craze but this recipe is really good! I’ve made it 3x now, each time I’ve used frozen wild blueberries and dairy free blueberry yogurt. One time I didn’t have vanilla yogurt so I added some vanilla extract.
Amazing! So happy you loved these ones!
Thank you so much Monique for all your recipes! They are soooooo good! I cannot name them all, but you are my no#1 go to site when I need ideas! All so healthy, delicious, awesome ingredients that you use! You’re the best! Keep it up! Oh and the Best Healthy Carrot cake is outstanding! 😉
So happy to hear that, Josie! I’m glad you’re finding recipes here that you love 🙂
My new fave breakfast! I subbed coconut milk for the almond milk, and it was absolutely delicious!! Thanks for an awesome recipe!
Perfect! Glad you love this one!
Thanks for this recipe! I tried it and it was great <3 I used a mix of frozen fruits but it worked out really well. Yumm
Absolutely! Happy to hear that 🙂
We made these last week for breakfast all week. So good! 🙌🏻🙌🏻 So flavorful and very filling! Husband approved-he said he loves all the flavors!
Amazing! So happy to hear that!
This is a nice recipe – not too sweet until you mix in the jam. I subbed in PB2 for actual peanut butter.
Great! Glad you enjoyed!
These are amazing! They are so filling and taste just like a PB&J sandwich. And so simple to make the oat/chia seed blend the night before. Will definitely be making these again!
Absolutely! Glad you loved these!
Best breakfast!
Can I use frozen blueberries & do you have to use fast cooking oats?
Frozen blueberries will work, and I’d recommend regular, old fashioned rolled oats!
These look delicious! How long can they be stored in the fridge?
About 4-5 days!
These are so good!! I love overnight oats for an easy brekky and PB&J is my fave.
These are my fav, too! So glad you love them 🙂
This looks delicious but unfortunately we are a nut free/peanut free household. Any suggestions what else we could use as an alternative to replace the peanut butter?
What about pumpkin seed butter or sunflower seed butter?
Sure!
This is DELICIOUS! I made it today but used overnight steel cut oats instead =)
Great! Such a good breakfast 🙂
How long will these keep in the refrigerator, if I’m doing my meal prep on Sundays for the week? Thanks!
Overnight oats last for 3-5 days in the fridge! They’ll just get softer the longer that they sit.
omg this is absolutely amazing recipe. i realized my jars are 8oz instead of 12oz but it still turned out to be enough! i will definitely be making this again!!
Perfect!! Such a great breakfast.
Hi, You can’t get Siggis in Tanzania. What is the container size please.
Thanks
It’s 5.3 ounces (or 150g)!
Can’t wait to make this. Looks delish!
Seriously best breakfast!
Man, I am sure that you do get a peanut butter and jelly sandwich in a jar indeed! There’s the carby-grain-bready quality from the oats and obviously the peanut butter and jelly action. This is such a nice recipe–I would love to try it with coconut yogurt!
Absolutely! It’s my fancy pb&j 🙂
I am going to have to make this for my kids! I love finding ways to pack in protein without packing in extra sugar. Sometimes it feels as if we can’t have the best of both worlds so, thank you Siggi’s! Thanks for sharing!
siggi’s does an amazing job with their ingredients + flavors! Hope the kiddos love this one 🙂
We dont have siggis in Australia so I need to find an alternative. What size is the container of yogurt please.
Hi Robyn! It’s 5.3 ounces or about 150g.
YUM love PB&J and how much protein are in these oats!! I’m with you on all the no-bake recipes for summer months!
YES these are perfect post-workout (or just a filling breakfast!)
Blueberries and peanut butter are one of my favorite combos for overnight oats! My husband takes it to work a lot! I love the addition of jam!
Mine too! Love these on-the-go.
If you’re using a coconut yogurt, can You also use a coconut milk?
Sure!
This looks so delicious! All of your recipes always turn out amazing. What brand of blueberry jam do you recommend that is low sugar?
Thanks Lexi! I usually get it from Trader Joe’s 🙂 I think it’s their blueberry preserves!
