Peanut Butter and Jelly Overnight Oats

You’ll love waking up to these peanut butter and jelly overnight oats! Protein-rich peanut butter and chia seed jam are swirled in with the creamy oats for a delicious and healthy breakfast.

I’ve been making and enjoying overnight oats for years, but I feel like I’ve never been able to get a good picture of them. I usually mix them in a storage container in a rush before heading to bed. Nothing against my typical glass storage containers, but they’re just not super cute.

This week my overnight oats got an upgrade. From glass storage containers to Weck jars and they look so much more sophisticated… almost like a breakfast you’d buy out at a coffee shop!

I’ve made peanut butter overnight oats before (and peanut butter cup overnight oats), but now we’re making the true classic — peanut butter and jelly overnight oats. I used a little peanut butter and plant-based protein powder to amp up the protein and a batch of homemade chia seed jam for a boost of fruity flavor and a pop of color.

Ingredients Needed for Peanut Butter and Jelly Overnight Oats

  • old fashioned rolled oats – rolled oats are the best for overnight oats. Instant/quick oats and steel cut oats don’t work the same because they don’t absorb liquid the same way rolled oats do
  • almond milk – I like using unsweetened vanilla almond milk, but any type of milk will work
  • peanut butter – I love peanut butter for this recipe (especially since it’s PB&J themed, but any nut butter that you enjoy would work for this recipe
  • vanilla protein powder – I use a plant-based vanilla protein powder that is sweetened with stevia. If your protein powder isn’t sweetened, you’ll likely want to add a little sweetener like maple syrup to your oats
  • sea salt – a pinch of sea salt is the perfect flavor enhancer and brings out the nutty flavor of the oats
  • strawberry chia jam – this homemade chia jam is unsweetened and perfect in this recipe, but if you don’t have time to make chia jam you can use store-bought jam.

Overnight Oats Ratio

The base “recipe” for overnight oats is so simple! The hardest part is getting the right ratio of oats to liquid, but if you follow my recipes you’ll be set!

I aim for a 1:1 ratio of rolled oats to milk, plus half as much yogurt. So for 1 cup of oats, I use 1 cup of milk + 1/2 cup of yogurt (or an additional 1/2 cup of milk). For this recipe, I’m skipping the yogurt and using the extra milk. This seems to give the oats the perfect consistency, not too thick, but not soupy. For the liquid, I usually go for non-dairy milk like almond milk, but you can use whatever milk you have on hand and if you really want to experiment you can try using different liquids like fruit juice.

How Long Do Overnight Oats Need to Soak?

Given the name, you’d assume overnight oats need to soak overnight, but you can actually make them in 2-4 hours if you’re in a rush. While it does take some time for the oats to absorb the liquid, they don’t necessarily have to be soaked overnight.

I recommend at least 8 hours for true overnight oats, but there have been mornings where I decide I want overnight oats for breakfast even though I didn’t prep them the night before. When this happens I’ll make them the morning of and let the oats soak for just 2-4 hours. With this quick soak, they’re not as soft as overnight oats that have soaked longer and they’re a bit more liquidy, but they’re still delicious.

How Long Do Overnight Oats Last?

When stored in an airtight container in the fridge overnight oats should last for up to 5 days. They will soften more the longer they sit so I find they’re best on days 1-3, but they’re still safe to eat on days 4 and 5. With this said, overnight oats are great for meal prep. Feel free to make a whole batch for the week on Sunday.

Can You Eat Overnight Oats Hot?

Short answer, yes! You can definitely warm up overnight oats, but the whole point of overnight oats is to eat them cold like muesli. Even if you think cold oats sound strange, I recommend giving it shot before you write them off. Of course, if you simply can’t do the cold oats you can always heat them up. Just pop the overnights oats in your microwave, cooking in 30 second increments until the oats are warm throughout and enjoy.

You’ll love waking up to these peanut butter and jelly overnight oats! Protein-rich peanut butter and chia seed jam are swirled in with the creamy oats for a delicious and healthy breakfast.



  1. Make jam: Make a batch of chia jam following the recipe for my strawberry chia seed jam.
  2. Combine ingredients: In the meantime, put oats, almond milk, peanut butter, protein powder and sea salt in a bowl and gently stir them together until the protein powder has dissolved. It’s okay if the peanut butter is a little clumpy.
  3. Let set: Cover the bowl and put it in the fridge for 3-4 hours, or overnight.
  4. Serve: Once the overnight oats have set up (and absorbed most of the almond milk) you’re ready to serve them. You can simply separate the overnight oats into two containers and use the berry chia jam as a topping or create layers with it. To make the layered version simply place 1/4 of the overnight oats in a container, place 1/4 of the berry chia jam on top, cover with another 1/4 of the overnight oats and top with more berry chia jam. Use remaining oats and chia jam to make a second bowl of layered overnight oats and serve. Drizzle more peanut butter on top, if desired.
  5. Store: Overnight oats will keep for up to 5 days in the fridge in a sealed airtight container.


  • Protein powder: If you don’t want to use protein power, simply add a couple tablespoons of Greek yogurt in place of the protein powder or omit the powder completely.
  • Jam: My homemade chia jam is unsweetened and perfect in this recipe, but if you don’t have time to make chia jam you can use store-bought jam.
  • Peanut butter: If you don’t have or are allergic to peanut butter, you can use any nut or seed butter instead.

      SOOOO GOOD! I liked this one a lot more than the peanut butter overnight oats. The strawberry chia jam adds an enticing sweet and acidic zing that I absolutely loved.

      I used PB powder instead of regular peanut butter and I love how it turned out. I have had that powder in my cupboard forever and finally have a use for it!

      This and the banana bread overnight oats are my top favorites so far!

      How much is a scoop of protein powder exactly? My vanilla protein powder doesn’t have a measured scoop.

      1. Brittany Mullins
        April 10, 2020 AT 4:19 pm

        I’d say about 25-30 grams, which is about 2 Tablespoons.

      How long can these stay in the fridge? Would I be able to make 5 of them for a M-F breakfast and be ok?

      Do you heat them up or eat cold?

      1. Brittany Mullins
        February 20, 2018 AT 3:55 pm

        Most people eat them cold but you can certainly heat them up the next morning if you don’t want to eat them cold. 🙂

      Does it make a difference if you don’t include the protein powder?

      1. Brittany Mullins
        August 10, 2017 AT 11:00 pm

        Hi there! You can definitely make it without the protein powder. It might be a bit thinner so you can add less almond milk if needed, but it should be fine!

      If I want to use peanut butter instead of peanut flour, do I still add it to the mixture that’s going in the fridge? Or do I add it the next day, right before eating? Dumb question, I know; but I just don’t want to screw up the recipe 🙂

        January 17, 2017 AT 10:23 am

        LIIZZZ!!! Hi friend. 🙂 I would try adding around 1-2 Tablespoons of actual peanut butter into the mixture before putting it in the fridge. It doesn’t have to completely blend in!

      Thank you for writing about overnight oats – they are my new favorite thing! I made a batch last night with a drizzle of honey, a dash of cinnamon, a tablespoon of dates and a pinch of coconut. It was delicious. The possibilities are endless and I look forward to trying out different combos!

      Do you have any alternative suggestions for peanut flour? Would coconut flour make it too dry? What about arrowroot powder?

      I love the heart in the center! So cute! I also LOVE LOVE LOVE overnight oats. After reading one of your past overnight oat posts, I jumped right on board. Being on a candida cleanse for the better part of the past year, I have totally missed my overnight oats. Indulge for me 😛
