Peanut Butter Banana Oatmeal is my favorite kind of breakfast. It's wholesome, yummy, and quick and easy to make. And even more importantly? It's sooo good.

So good, in fact, that the first time I ever made this recipe, my extremely picky then-3-year-old requested to eat the leftovers for dinner. And then she asked for the same thing for breakfast the next day. So given that this healthy oat breakfast is loaded with fiber, calcium, protein, and potassium, I guess it would be an improvement over the cheese quesadilla, grilled cheese sandwich, and/or cheese pizza (are we sensing a theme here?) that she traditionally requested on a daily basis.

So what makes this Peanut Butter Banana Oatmeal good enough that my food-rut daughter has always been willing to trade her beloved carbs and cheese for it? Well -- in case you're not already privy to the fact -- bananas and PB get along swimmingly! In fact, this recipe is actually a spin on my Peanut Butter Banana Overnight Oats.

So if you already know that you enjoy peanut butter oatmeal or banana oatmeal, I highly encourage you to combine the two and give this one a try!


It takes just a few minutes and a few basic ingredients to elevate an otherwise boring (sorry) oatmeal breakfast into something special:

Labeled ingredients to make Peanut Butter Banana Oatmeal.
  • Milk. I use whole milk, but skim milk, 2%, or your favorite non-dairy substitute will work as well.
  • Oats. This Peanut Butter Banana Oatmeal recipe was developed for speed using quick oats, but you could certainly adapt it to using regular/old-fashioned rolled oats. Just keep in mind that the stovetop cooking time for rolled oats will be about 5 minutes, as opposed to a minute or two for quick oats.
  • Banana. Mashed. The browner, the better!
  • Peanut butter. Use creamy or crunchy...whatever floats your boat. You could also opt to swap in your favorite nut (or non-nut) butter, such as almond butter or sunflower butter.
  • Ground cinnamon, pure vanilla extract, and salt. These ingredients are the difference makers for flavor that pops.
  • Honey. Optional, depending on the sweetness of your banana and/or how sweet you prefer your final oatmeal.

Then, to add even more flavor and texture, feel free to garnish your bowls with sliced bananas, chopped roasted peanuts, and even more cinnamon!

Tweak the Sweetness

If your banana is nice and sweet, this oatmeal might be perfect for you as-is.

But if you'd like it a tad sweeter, feel free to squeeze in a bit of honey.

I find that 1 tablespoon stirred into the pot gives this oatmeal a quality not unlike Baby Bear's porridge (AKA, juuuust right)...but how much you prefer to add is up to you. 🙂

I happen to think this Peanut Butter Banana Oatmeal is perfect as-is. But it's easy to adjust it if you prefer plain peanut butter oatmeal or plain banana oatmeal instead...simply omit the opposite ingredient!

Making It Ahead of Time

I used to solely consider this Peanut Butter Banana Oatmeal a hot, fresh breakfast to be whipped up in the morning a matter of minutes. But in the many years that I've been making it, I've determined that it also works beautifully as a healthy oat breakfast that can be made ahead of time and then simply reheated all week long!

As written, this recipe yields two servings. So sometimes, I'll double or even triple the recipe in a big pot (I flat-out multiply all of the ingredients by my decided number and it works just fine). It does take a bit longer to bring a larger amount of milk to a boil, but the difference is negligible. After the oatmeal is done, I'll allow it to cool a bit, transfer it to an airtight container, and then pop it in the fridge.

To reheat, simply plop your desired amount of Peanut Butter Banana Oatmeal into a bowl, top with a splash of milk, and then microwave for about a minute. Stir, taste, and determine if the oatmeal needs more milk or more heating time to achieve your preferred consistency and temperature.

And that's it! Peanut butter oatmeal is good. Banana oatmeal is great. But Peanut Butter Banana Oatmeal can't be beat!

Seriously, friends, making a pot of this deliciousness for breakfast doesn't take much longer than pouring a bowl of cereal. But it's so much healthier, tastier, and more filling. Plus, a little birdie told me that it even makes for a good brinner if you don't feel up to cooking a full-fledged meal one night...or, you know, if you just don't feel like battling a preschooler over cheese quesadillas yet again. 😉

    This pb banana oatmeal turned out so yummy! I used old fashioned oats because that's what I had on hand. I added chopped peanuts and I loved the crunch!

  2. 5 stars
    This is so delicious! I just made this oatmeal for my family and we all love it. I added flax powder, hemp hearts, chia seeds, pecans, strawberries and more milk. I also used rolled oats instead because I didn’t have quick oats. I will definitely make this again! Thank you.

    1. 5 stars
      Ahhhh soo sooo delicious, I over ate 😊.... thank you so much Samantha.
      Definitely ⭐⭐⭐⭐⭐

  3. How many servings does this make? I'm feeding 9 kids this morning and can't seem to find the serving amount. Just need to know if I should double or triple it.

    1. Hi Athena! Sorry if it was hard to find, but the number of servings is at the top left corner of this recipe card. This recipe makes 2 (adult) servings, so I'd probably triple (or quadruple, depending on their ages) the recipe for 9 kids.

  4. 5 stars
    This recipe is getting me through college midterms and I can't thank you enough ? it's so tasty, filling and easy

  5. Could I make a large batch of this and put it in individual containers to heat up throughout the week? How long will it keep once it's made? I can't wait to try this! On a whim, I stirred some peanut butter into my instant bananas and cream oatmeal this morning then immediately started to search for recipes to make it from scratch (or at least, more natural and less processed). 🙂 Thanks!

    1. Hi Robin! You can definitely make a batch of this oatmeal ahead of time and reheat it throughout the week (I'd expect it to keep in the fridge for 4 or 5 days). That being said, you'll probably need to stir in a little milk before reheating as it will thicken once chilled. Hope that helps...enjoy!

    1. I imagine the calorie count is closer to 500 calories, depending on the milk you use, etc. If you were to substitute regular milk for almond milk and, with an estimate of the calories in the various amounts of toppings, that roughly accounts to 465 calories, give or take (per serving). Sorry if this is inaccurate, I just calculated it with some exact calorie counts and some estimates (for honey, peanuts, etc). It also depends on the type/brand of ingredients you use, seeing as some are higher in calories than others.

  6. This looks so yummy! I've never been a fan of oatmeal, but thanks to you I've discovered I like it. I'm still making the baked oatmeal and I'm looking forward to trying this too 🙂
