Peanut Butter Blueberry Overnight Oats

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

1. Mix the liquids. Start by stirring the yogurt and almond milk together until smooth.
2. 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.
3. 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.
4. 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.
