My PB and J Overnight Oats are a balanced breakfast that taste like your childhood favorite. Healthy fats, fibre and fun to start your day!

Peanut butter and jelly is such a classic combo that I still eat it all the time as a grown up. Nothing beats it, whether it's in a classic sandwich or my PB and J quesadilla. These PB and J overnight oats are no exception: made with whole grains, homemade chia jam and rich, creamy peanut butter, there is so much to love about this balanced breakfast.
Why This Recipe Is Dietitian Approved
- Protein + fibre. These PB and J overnight oats have 31g of protein and 11g of fibre that will keep you full and satisfied all morning long.
- Meal prep friendly. I love making high protein overnight oats in my meal prep rotation because they're easy to prepare and store well.
- Make breakfast fun. There's no better way to make breakfast fun than a dose of nostalgia. PB and Js always take me back to my childhood.
Ingredients
Oats. You can use quick, minute or rolled oats. Quick or minute oats will result in a smoother texture, while rolled oats will be chunkier. Steel cut oats will not work as they are much tougher and require cooking.
Chia seeds. I do not recommend skipping the chia seeds, as they thicken the oats, creating a ‘pudding-like’ texture. They also offer 5g of fiber per tablespoon. Black or white chia seeds will both work.
Protein powder. Any vanilla flavoured protein will work. My favourite is THIS. I have also provided some substitutions in the text below the recipe if you don't like protein powders.
Salt. A small pinch of salt helps bring out the flavour of the jam and peanut butter. If your peanut butter is salted, you can skip this.
Milk. You may use any milk of choice, but I use dairy or soy for the highest protein.
Greek yogurt. My secret to creating a smooth and creamy texture while also helping to boost the protein. I typically use plain Greek yogurt.
Peanut butter. I recommend using a natural, creamy peanut butter. Look for one with just roasted peanuts (and salt) as the ingredients.
Chia jam. This is my favourite jam (with minimal added sugar). You can use my recipe here or you can use any jam you have on hand.
Peanut butter powder. Optional, but this helps strengthen the flavour of the peanut butter oats. It also has an extra boost of protein!

Instructions
- In a medium bowl, whisk together milk, Greek yogurt, 1 tablespoon of peanut butter and vanilla extract and mix until smooth. Whisk in oats, chia seeds, vanilla protein powder and salt (if using). Set aside to thicken slightly for about 5 minutes.
- Add half of the peanut butter oats to a 10 oz jar. Add a layer of chia jam and top with the remaining peanut butter oats.
- Top with the remaining 1 tablespoon of peanut butter (I like to microwave mine for about 15 seconds and pour it over the top to get a smooth, spreadable layer). Cover and place in the fridge for at least 3 hours, preferably overnight.
- In the morning, top with crushed peanuts and additional chia jam if desired.

Frequently Asked Questions
Of course! PB and J is the classic flavour, but you could do almond butter, cashew butter, or another nut you like.
My personal favorite is usually the natural peanut butter from Costco! I find it to be the best price and it's only ingredient is roasted peanuts!

- 3 tablespoon chia jam homemade or jam of choice
For topping:
- ½ tablespoon crushed peanuts optional
- Additional chia jam
Instructions

Notes
- Protein powder: replace with 1 tablespoon of peanut butter powder or you may leave it out completely. If you are skipping the protein powder, I recommend adding some additional sweetness (ie. 1 teaspoon of honey).
- Greek yogurt: add an additional 2 tablespoon of milk. Please note this will result in slightly thinner overnight oats.
- Peanut butter: you can substitute the 1 tablespoon of peanut butter with 1 tablespoon of peanut butter powder and an additional 1 tablespoon of yogurt.
