This peanut butter banana oatmeal is creamy, voluminous and will keep you full all morning long! Plus, it only takes about 10 minutes to make and is vegan + gluten-free.

Now that I’ve shared how to make oatmeal, I have to share my  favorite oatmeal recipe ever… peanut butter banana oatmeal.

Peanut butter and banana is one of the best combos so it makes sense that this peanut butter banana oatmeal is sooo good. If you’re looking for a healthy breakfast recipe to add to your rotation, this would be a great recipe to try. Each bowl has around 370 calories, 17 grams of fiber (woot!), and 11 grams of protein!

How to Make Voluminous Oats

As a volume eater I love being able to eat a big bowl of something while still feeing good about it. That why I love salads so much!

Oatmeal, especially when made with extra water and pumped up with bananas and chia seeds, is a volume eater’s best friend. The trick 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-diary 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. The key is making sure you stir the oats while cooking so the banana slices break down and the chia seeds get even distributed rather than clumping in one spot. No one likes clumps of chia.

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. My trick for making it super drizzly? Add 1/2 teaspoon melted coconut oil to 2 Tablespoons of peanut butter and stir to combine. The peanut butter will thin and you can get your drizzle on.

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
  • chia seeds
  • cinnamon
  • sea salt
  • water – you can also use non-dairy milk or a blend of both
  • peanut butter or another type of nut butter

How to Make Peanut Butter Banana Oatmeal

Making this peanut butter banana oatmeal is a breeze. Just start by adding your oats, banana slices, chia seeds, cinnamon and sea salt to a pot. Add water and stir to combine.

Heat over medium-high heat for 8-10 minutes or until all the liquid has been absorbed. 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. You’ll know the oatmeal is done when all the liquid is absorbed and the oats are thick and fluffy.

Portion oats into two bowls and serve with peanut butter, banana slices, and a sprinkle of chia seeds. Add a splash of non-dairy milk and/or maple syrup on top before serving, if desired.

Peanut Butter Banana Oatmeal

Description

The ultimate healthy breakfast recipe, this peanut butter banana oatmeal is creamy, voluminous and will keep you full all morning long! Plus it only takes about 10 minutes to make and is vegan + gluten-free.


Ingredients

  • 1 cup old fashioned oats
  • 1 banana, sliced (save a few for topping)
  • 1 Tablespoon chia seeds
  • 1 teaspoon cinnamon
  • pinch of sea salt
  • 3 cups of water, non-dairy milk or a blend of both
  • 2 Tablespoons peanut butter or another type of nut butter

Instructions

  1. Add ingredients into a pot: Add oats, banana slices, chia seeds, cinnamon and sea salt to a pot. Add water and stir to combine. Heat over medium-high heat for 8-10 minutes or until all the liquid has been absorbed. 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. You’ll know the oatmeal is done when all the liquid is absorbed and the oats are thick and fluffy.
  2. Serve: Portion oats into two bowls and serve with peanut butter, banana slices, and a sprinkle of chia seeds. Add a splash of non-dairy milk and/or maple syrup on top before serving, if desired.

Notes

  • 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.

      My go to breakfast! I’d recommend turning off the heat when the oats are emerging from the liquid, stiring it a bit and leaving for 3-5 minutes. The texture gets exstra thick and it is soo tasty.

      This was super delicious! I did make a few subs…used half skim milk and half water, honey in place of the syrup, then skipped the pb but added a sprinkle of chopped pecans and a handful of blueberries. This will be my basic oatmeal from now on! Going to try a carrot cake version of it next. Thank you sooo much!

      Not as sweet as I’d hoped with the banana. Still added some brown sugar. It was a tough texture for my 2 1/2 year old, she spat it out :(, too slimy for her. I liked it and the healthiness though.

      Soso yummy and love that i found a new way to consume those nasty little seeds cant stand they jelly feeling they get when i put them in water.

        haha. Chia seeds definitely have a funny texture, but they work great in oats because you don’t notice it. You might also like these oatmeal chia cookies!

      Too much water, it doesn’t cook down.

        January 20, 2021 AT 9:17 am

        Hi Nelody. I double up the water to make it extra creamy. I’ve made this recipe hundreds of times so I know for sure that it will cook down if you follow the recipe.

      Yum! I eat oatmeal most mornings and this was a nice way to liven it up a bit. I added a touch of vanilla while the oatmeal was cooking and topped it with blackberries and pecans.Your tip on adding the melted coconut oil to the peanut for easy drizzling was clutch! Big fan and my sweet tooth thanks you 😄

      I made this using oat bran actually – because that, along with a bunch of chia seeds (which I bought and didn’t end up being a fan of in smoothies!) was what I was trying to use up. It turned out delicious, I used a bit less plant milk though. I also added some honey because I have a sweet tooth.

      I’m not usually a breakfast person but this might convert me.

      1. Brittany Mullins
        October 1, 2020 AT 11:33 pm

        Oh yay!! So glad this was a hit for you, Hannah. Good to know that oat bran worked!

      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.

      It was SO BAD. Do
      Not try this recipe. It was watery, and tasted so disgusting. Ruined my breakfast

      1. Brittany Mullins
        August 17, 2020 AT 3:12 pm

        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?

        1. Kristen
          January 17, 2021 AT 7:23 am

          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.

          1. Brittany Mullins
            January 17, 2021 AT 7:13 pm

            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!

      July 2, 2020 AT 2:11 pm

      Is it kept in an airtight container?

      1. Brittany Mullins
        July 2, 2020 AT 8:11 pm

        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.
