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
- Naturally Sweetened – No need for added sugar! The banana slices provide plenty of sweetness to these oats.
- Nutritious – Between the oats, chia seeds and peanut butter, this bowl is loaded with fiber, healthy fats and protein.

- Quick and Easy – This bowl of oats is made with just a handful of ingredients you probably already have in your pantry, and it comes together in about 10 minutes. Perfect for busy mornings!
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.

Hello Brittany,
I am a bloke, so excuse the basic lack of cooking knowledge….I like the idea of the peanut butter oat chia banana mix but can I add yoghurt instead of milk – I have had to dump my bran stick/oats/yoghurt breezy due to gas issues – seem to be cause by the bran!!
Hey Paul. I don’t think subbing yoghurt for the milk will work for this recipe… it will be too thick, but I have a protein-packed Greek yogurt oatmeal recipe that you might enjoy. Be sure to check that one out!
This is THE BEST oatmeal recipe, I make it all the time! I like having it cold on top of plain or coconut yogurt with additional seeds and maple syrup drizzled on top instead of PB. 🙂
Yay! I’m so excited to hear that you love this oatmeal recipe, Danielle. It’s my favorite oatmeal recipe too! And I love the idea about having it cold with yogurt. Sounds delicious.
Is it really 9 cups of water/milk when making the recipe times 3? It’s a lot of liquid for 3 cups of oatmeal. Just want to make sure I’m not doing something wrong.
Yes, 9 cups would be correct!
Loved this recipe! I’ve been starting a more healthy lifestyle, and I’m also at classes for 5 hours a day – it’s been difficult to find something that’s healthy but will keep me full! This definitely was the answer, and it was delicious!
I really enjoyed the idea of this recipe, but the result came out funky. It says 8-10 minutes in the recipe but mine didn’t even start absorbing until the 20-25 minute mark. The end product looked more like glue than it did oatmeal. Any suggestions?
That’s so strange. I think the reason is came out so thick and glue-like is likely because you cooked it too long. Did you use milk or water to cook it? And what temperature were you using?
This happened to me too! I cut the recipe in half and used almond milk. I cooked it on medium heat… didn’t turn out fluffy like your pictures! Still smells delicious!!! Just wondering what I did wrong?
Oh no!! So sorry to hear that. Did you let it sit or did you keep mixing it together? That’s so strange that happened!
Amazing! Great flavor and consistency!
Even my 2 picky eaters loved it, will definitely
be making this a staple in our house!
Thanks!!!
I followed the recipe and have cooked it for 10 minutes and still have tons of liquid…I’ll cook it a little longer and hope it turns out!
I just made this and it was delicious! Thank you for the recipe!
This was honestly the best oatmeal recipe I’ve ever had. It took a lot for me to make it, from past issues, but when I ate it, my tastebuds fell in love! I made half of the servings, just for one person and I used almond milk. This time, I cooked it again but instead with coconut milk and it’s even better! I had my mom try it and she fell in love and wouldn’t stop eating mine!! I’m officially calling it. This is the BEST oatmeal recipe in the world.
This is my go-to oatmeal recipe – I make it all the time! Thanks so much for sharing. So good<3
Yay!! It’s my go-to recipe too. So glad you like it, Mandalee. And thank you so much for coming back to leave a comment and star rating for the recipe. It’s super helpful!
