Breakfast isn’t my favorite meal by any means, and I would probably skip if allowed. 

But alas, the kids demand breakfast every. single. day for some reason… so we comply. By we, I mean my husband, because I rarely ever make breakfast.

The only reason I would ever make it is if I accidentally make pumpkin muffins, granola, or blackberry bread in the afternoon and we happen to eat it the next morning for breakfast.

Then, being an awesome wife, I make my husband acknowledge the fact that I made breakfast. Haha. “See I make breakfast sometimes!”

Jokes aside, he makes breakfast so I can work before the kids are up. It’s very sweet of him.

The best part about this recipe is that it can be prepped the night before, pulled out of the fridge in the morning and it is totally done! Score!

Tips For Making Peanut Butter Overnight Oats:

  • If you have a peanut allergy, swap out the peanut butter for sunflower butter  or almond butter.
  • This recipe also works as a great snack. It needs a minimum of 3 hours in the fridge, so make it in the morning and you have a healthy snack for after lunch or school.
  • You can dress this recipe up a few ways. Find some of my favorite ways below.
  • You can use any milk you would like, whether it be a plant-based milk or cows milk. If you use a sweetened milk, than you may want to adjust the amount of maple syrup.
  • If you have celiac disease or are strict gluten free, make sure to use certified gluten free oats. Regular oats can easily be cross-contaminated with gluten due to using the same equipment.

Fun Add Ins For Peanut Butter Overnight Oats

  • Chocolate chips
  • A spoonful of strawberry, grape, or raspberry jam! Hello peanut butter and jelly oats!
  • Diced fresh fruit – bananas, apples, or pears would work wonderfully. I would wait to add them in the morning.
  • Add a scoop of collagen peptides for a extra boost of protein.  If vegan, use a small scoop of your favorite vanilla protein powder.

Peanut Butter Overnight Oats FAQ

What are overnight oats?

They are oats that have been soaked overnight in a liquid, usually milk (regular or plant-based), and then eaten.

Do you eat overnight oats cold?

You can eat them hot or cold. Usually they are eaten cold so you can just grab them to go, but you can easily heat them up to eat them warm. Totally get it if cold oatmeal doesn’t sound appealing.

What types of oats can you use?

Rolled oats work best, but I will also use quick oats and they work great. Steel cut oats may be too thick and won’t soften enough to eat. Instant oats will get too soggy and mushy, so I wouldn’t recommend.

How long does this recipe last in the fridge?

This recipe will last 2-3 days in the fridge no problem. You can double or triple this recipe and have breakfasts prepped for a few days! It doesn’t get much easier than that.

Are overnight oats healthy?

Yes! They may even be slightly more nutritious that regular oats. This is because they are soaked overnight which helps breakdown the phytic acid in the oats.

Phytic acid is a naturally occurring anti-nutrient that blocks the absorbing of certain nutrients, like magnesium. Soaking allows the nutrients in oats to be more absorbable to the body.

Soaking may also make them more easily digested. (source)

Plus, since bananas, chia seeds, and are milk included in the recipe it is packed with even more healthy ingredients. Protein, healthy fats, omega-3s, potassium, calcium, and much much more. There is much to love with this healthy breakfast.

Is adding peanut butter to oatmeal healthy?

Yes! Peanut butter is full of healthy fats and is a great way to add protein.

Is this recipe vegan?

If you use a plant base milk and add maple syrup (rather than honey), then yes it is vegan. If adding chocolate chips, make sure they don’t contain milk or other non-vegan ingredients.

  1. I hated PB when I was a kid so I didn’t have a PB&J until I was 21. Then I couldn’t get enough. Still don’t care for grape jelly. Can’t wait to try this.
