These PB&J Overnight Oats are full of creamy Peanut Butter and Chia Jam. A hearty, filling, and a great way to enjoy the classic sandwich…for breakfast!
While I used to eat a Peanut Butter & Jelly Sandwich every day for lunch, I’ve since moved on to other options. Now, I just eat it for breakfast….kind of 😉

These PB&J Overnight Oats taste just like the classic sandwich, but are made with only 5 plant-based ingredients, easy to prep, and downright delicious! I love to make a big batch of these on Sunday and have them as a filling and nourishing breakfast throughout the week. They’re also a great source of Complex Carbs, Healthy Fats, Protein, and Fiber – all of which will keep you full until lunch.

Because Oats are a grain, they taste similar to the “bread” portion of the sandwich. But what’s the secret to getting that great peanut-ty flavor throughout?! Peanut Milk! Sounds complicated, but it’s actually quite simple. All we’re going to do is whisk some Creamy Peanut Butter together with some Filtered Water, and use that as the liquid in this recipe. Non-Dairy Milk is essentially Nuts + Water anyways, so the idea is not too crazy when you think about it.

Obviously, we’re going to need some Jelly up in here too – I opted to use my Chia Seed Jam recipe to keep things homemade, preservative free, and refined-sugar free. To get the full “sandwich” effect, I nestled a thick layer of Jam in the center of the creamy, dreamy Oatmeal (YUM!), though you could also just spread it on top.
These PB&J Overnight Oats have a great Peanut flavor alone, but I also love to top them with extra Peanut Butter and Peanut Pieces for additional flavor and Crunch. I think that’s what really takes this recipe to the next level!

Let’s be honest – can you really ever go wrong with this classic flavor combo? I think this recipe will be easily enjoyed and readily devoured by kids and adults alike. And considering how easy it is to make and prep ahead of time, it’s also perfect fuel for the school or work week!

A Few Final Thoughts:
- While it won’t be a PB&J…feel free to sub the Peanut Butter with another Nut or Seed Butter if you have an allergy. It will still taste delicious, that’s for sure!
- I used my homemade (and easy) Chia Seed Jam recipe for these overnight oats, but you can substitute with store-bought jam or jelly if you’d like.
- The recipe below makes one serving of Overnight Oats, but I like to double, triple, etc it for Meal Prep. Just mix everything together in a big bowl, then divide evenly into smaller jars!

PB&J Overnight Oats
These PB&J Overnight Oats are full of creamy Peanut Butter and Chia Jam. A hearty, filling, and a great way to enjoy the classic sandwich…for breakfast!
- Prep Time: 10 Minutes
- Cook Time: 0 Minutes
- Total Time: 10 minutes
- Yield: 1 Serving 1x
- Category: Breakfast
- Method: No Bake
- Cuisine: American
Ingredients
Note: double, triple, or quadruple the recipe for multiple servings!
- 1 tablespoon creamy peanut butter, plus more for topping
- 3/4 cup dairy-free milk (or sub water)
- 1/2 cup quick-cooking or rolled oats*
- 1 tablespoon chia seeds
- 1 teaspoon maple syrup (Optional; add more to taste)
- 2+ tablespoons Chia Seed Jam (or sub store-bought)
Instructions
- Peanut “Milk”: Add the peanut butter to a medium bowl with a small amount of the milk. Use a whisk to “blend” the peanut butter with the liquid, and gradually add the remaining milk while whisking until a smooth, peanut butter “milk” forms. (Note: an electric frother works well for this!)
- Dry Ingredients: Add the oats, chia seeds, and maple syrup to the bowl. Mix well and let sit for 5 or so minutes, so the oats can absorb some of the moisture.
- Layer: Scoop half of the oatmeal into the bottom of a glass jar or tupperware, then layer with jam. Pour the remaining oatmeal over top of the jam, and top as desired. I like to keep things simple with more PB and jam!
- Serve & Store: Let sit for another 5 minutes and enjoy immediately, or store in the refrigerator for up to 5 days.
Notes
- Oats: Use gluten-free oats if necessary. You can use any “variety” of oats other than steel-cut oatmeal for this recipe.
- Nut Butter: Feel free to sub the peanut butter with another nut or seed butter – keep in mind that whatever you choose will affect the flavor.

I have meal prepped these so many times and given them to friends and we all agree- they are delicious!! My favorite overnight oats recipe I have ever made. Will be eating these for breakfast until further notice. I sometimes replace the PB for cookie butter and try different types of jams.
Delicious!! Thanks Toyo 🙂
I let my kids pick a new overnight oats recipe to try and this was their choice. We used their favorite jam instead of the chia seed jam included but otherwise followed the recipe completely. They loved it and wanted me to mark it as a favorite. I would like to attempt with the chia seed jam sometime in the future because I think that sounds amazing.
That’s awesome, Mary! 😊
Thanks for sharing! Do they keep long?
You can store them in the fridge until ready to serve; the Oatmeal will keep well for up to 6 days.
This looks so good! What a great way to eat this childhood favorite in an adult friendly version!
Thanks so much!
Let me just say. A-MAZ-ING. If you get the chance to try this, please do! You cant really go wrong with PB and J, though. I used some strawberry chia jam I made a few nights prior, and added pumpkin seeds to the top! Heated up for around 90 seconds, and man, was I in heaven.
That’s awesome! Thanks for sharing!
I wanted to like this so so very much and. My oats had an unpleasant tangy aftertaste that even extra peanut butter and some maple syrup could not cover. Could something have been wrong with my greek yogurt(I strained regular homemade yogurt??
Hi Bella, there is no yogurt in this recipe!
Do you have nutritional data for this recipe? I tried it last night, and loved it!
Hi Liliana! I do not post the nutritional information for my recipes, but there are plenty of free online calculators that could help you out with that 🙂
How big are the jars you use?
They each hold around 1 1/2 cups 🙂
I went to Walmart and bought a case of 8 oz mason jars made by ball the original maker of mason jars very inexpensive and they work out perfect for these recipes.
This was great. I used crunchy PB and I thought it worked really well. Plus there were small peanuts throughout. Been really enjoying the Chia Jam too. It was the perfect use of some blueberries on their last few days.
Yum – I bet the Crunchy PB was great!
You can’t ever go wrong with peanut butter and jelly together! I also discovered this sourdough bread made with oat flour and whole wheat flour from Lassens. I want to try making a peanut butter and jelly sandwich with it too, all along with these overnight oats! Can’t think of a better breakfast idea!
Great idea! I am going to try this out. Does it really last all week if you prep on sunday? I am always afraid oatmeal will spoil or something.
Yes, it will last through the week!
