Peanut Butter Oatmeal

This peanut butter oatmeal comes together in 10 minutes with simple ingredients for a quick and easy breakfast! It’s creamy, delicious and will keep you full all morning long.
I’ve been making this peanut butter oatmeal for over 7 years (which is crazy to think about!) and it’s still my favorite oatmeal recipe to date!
You just can’t beat the peanut butter and banana combo. It’s sooo good and probably my favorite flavor combination if you couldn’t tell from all my pb + banana recipes on the site like this peanut butter banana baked oatmeal, peanut butter banana bites, peanut butter banana pudding and chocolate peanut butter banana bark.

The trick to making this bowl of oatmeal so voluminous and filling is using double the amount of liquid typically recommended. Most old fashioned oatmeal packages recommend a 1:2 ratio so 1/2 cup oats and 1 cup of water, but when I make oatmeal I do 1/2 cup oats and 1 1/2 – 2 cups of water (or non-dairy milk). The oats take a little bit longer to cook, but they easily soak up all the liquid resulting in a much larger portion.
With this recipe, the banana and chia seeds help too. The banana slices add sweetness, but they also soften and expand making the oats extra voluminous while the chia seeds pack in a ton of nutrition and make the oats fluffy and thick.
And let’s not forget the peanut butter topping! It may not add a ton of volume but it gives the oats a delicious nutty flavor and a boost of healthy fat and protein, which will help keep you full through a busy morning!

Why You’ll Love This Recipe

Ingredients Needed

- rolled oats – old fashioned rolled oats are best for this recipe. If you have steel cut oats, try my recipe for steel cut oatmeal.
- banana – the banana slices melt into the oats giving them a fluffy texture and a subtle sweetness.
- cinnamon – I love adding cinnamon to my oats for a touch of warmth and sweetness without any sugar.
- chia seeds – a great source of omega-3s and fiber, chia seeds help thicken the oatmeal while adding a nutritional boost.
- water and/or milk – I like using a combo of water and milk (like almond milk) for some added creaminess, but you can use just water or just milk.
- peanut butter – I love the banana + peanut butter combo, but any nut or seed butter will work.

Recipe Notes
- Make it peanut-free: Skip the peanut butter and use almond butter, cashew butter, sunflower seed butter or tahini instead.

How to Make Peanut Butter Oatmeal

Step 1: Add oats, banana slices, chia seeds, cinnamon and sea salt to a pot. Add water and/or milk and stir to combine.

Step 2: Heat over medium-high heat for 8-10 minutes or until all the liquid has been absorbed. You’ll know the oatmeal is done when all the liquid is absorbed and the oats are thick and fluffy.
Brittany’s Tip!
Be sure to stir the oats several times while cooking to make sure the banana slices melt into the oats and the chia seeds don’t clump!

Oatmeal Toppings
The ingredients for this recipe are simple and all work so well together! But there are many other toppings I can think of that will take this peanut butter oatmeal a level up. Here are some ideas to try out:
- Fresh Fruit: Top your oatmeal with fresh slices of banana, berries (like blueberries or strawberries), or even diced apples.
- Chopped Nuts: Add some crunch with chopped walnuts, almonds, or pecans.
- Granola: Adding granola to oatmeal is one of my favorites! Try my homemade granola for that perfect crunch.
- Sweetener: I enjoy the sweetness from the banana alone, but a drizzle of honey, maple syrup, a sprinkle of brown sugar or even some chopped-up dates would be excellent ideas for those who have a bit of a sweet tooth.
- Chocolate: Peanut butter and chocolate are the perfect pair! Add in some chocolate chips, a chopped chocolate bar or some cacao nibs.
Storing Leftovers
If you have any leftover peanut butter oatmeal, you can easily store it in the refrigerator for up to 4-5 days. Just transfer the cooled oatmeal into an airtight container.
When you’re ready to enjoy it again, simply reheat it on the stovetop or in the microwave, adding a splash of milk or water to bring back its creamy consistency. Give it a good stir, and it’ll be just as delicious as when you first made it!
Frequently Asked Questions
Definitely! Quick oats will work just fine, but keep in mind they cook faster and will have a softer texture compared to old-fashioned rolled oats. If using quick oats, reduce the cooking time to about 3-5 minutes.
Stir, stir, stir. Make sure you stir the oatmeal regularly while it’s cooking. The chia seeds start to absorb the liquid and stick more often to the sides so stirring often helps prevent this. If you find the oats are sticking, lower the heat slightly and add a bit more liquid to keep things moving smoothly.
Yes! To turn this recipe into overnight oats just use all the same ingredients but reduce the non-diary milk to 2 cups instead of 3 cups. Mix everything together, let the mixture sit in the fridge overnight and enjoy the next morning with your favorite toppings.

Notes
- Make it peanut-free: Skip the peanut butter and use almond butter, cashew butter, sunflower seed butter or tahini instead.
- Meal prep: I like making two servings so I can save one for the next day, but if you don’t like eating leftover oats and are only cooking for yourself, simply cut all ingredients in half. For reheating you can use the stovetop or microwave. Just add the portion you’re going to eat and a splash of water or milk and heat until warm. In the microwave it shouldn’t take more than 30 – 60 secs.
- Overnight oats: Turn this recipe into overnight oats by using all the same ingredients but reducing the non-diary milk to 2 cups instead of 3 cups. Mix everything together, let the mixture sit in the fridge overnight and enjoy the next morning with your favorite toppings.

I made this yesterday and put one serving in the fridge. It was delicious fresh but I think it was even better the day after. Thank you for this!!
Ahh yay! So glad you enjoyed this recipe, Libby. 🙂
It tasted really good considering there was no sugar
Thank you for the recipe, I like to eat high volume foods with a low caloric impact. I did notice the calorie are off a bit and wondering what brands you are using? The oats, banana, and peanut butter alone are 580 calories.
Hey Brooke. This recipe serves 2. I think that’s why your stats are different.
oooohhhhhh! this was so good & easy! my kiddos were SO impressed…not really a cooking mom, but trying… so THANKS! YUMMMMMY
Ahh yay!! So glad this oatmeal turned out for you, DeAnna. Thanks for trying my recipe and for coming back to leave a comment + star rating. I so appreciate it. 🙂
It was SO BAD. Do
Not try this recipe. It was watery, and tasted so disgusting. Ruined my breakfast
Hey Emily – I’m so sorry to hear you didn’t like this. The oats definitely shouldn’t be watery. Did you change anything about the recipe?
Mine was also watery. The liquid might be too much for the recipe. 3 cups of liquid for one cup of oatmeal doesn’t match up.
Hey Kristen – Sorry to hear that. Did you add the bananas and chia seeds to this oatmeal when cooking and how long did you let the oats cook for? I’ve never had an issue with the oats turning out too liquidy!
Is it kept in an airtight container?
Hey Morgan – I normally make the oatmeal the morning I’m going to eat it, but you can certainly store this in an airtight container in the fridge if you are making this in advance.
Thank you for this amazing recipe! Will definitely be making this all the time now for breakfast or dessert!
Ahh yay!! That makes me so happy to hear, Kass. I’m so glad you enjoyed this recipe. Thanks for trying it and for coming back to leave a comment + star rating. I so appreciate it. 🙂
These oats are AMAZING! I love how fluffy and sweet they are without any added sweetener. The PB and banana is beyond delicious.
so quick, easy, & cheap!!! i loved this! it was so filling and tasted amazing with just the right amount of sweetness
THANK YOU SO MUCH!!!!
I really like the recipe! The fluffy oatmeal, and my favorite peanut butter with banana!
Love this recipe! We do oatmeal every morning in our house and this recipe is always in the rotation once per week. I love the idea of cooking the banana into the oatmeal so much that I’ve actually stolen it to use on other oatmeal recipes with fruits and nuts on top as well! It adds a slight sweetness without needing to use any added sugar.
So glad you’ve been loving this recipe, Arie! Thanks so much for taking the time to leave a comment + star rating. I really appreciate it. <3
