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 is a volume eater’s best friend… especially when made with extra water and pumped up with bananas and chia seeds! 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 – the banana slices almost 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.
  • sea salt – just to bring out all the flavors in the oatmeal.
  • water – you can also use non-dairy milk (like almond milk) or a blend of both milk and water.
  • peanut butter – I personally love the taste of peanut butter but any nut or seed butter will work.

How to Make Peanut Butter Banana Oatmeal

Making this peanut butter banana oatmeal is a breeze.

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.

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.

    I made this oatmeal today for breakfast and it was delicious. I love that no sugar is added but it is still sweet and so tasty. I’m definitely going to add this to my rotation.

    Best oatmeal ever!!! It was so good that I cant wait to have the second portion i saved for the next day. So delicious!! I will definitely be making this every week now. Thank you for sharing this recipe.

  3. I eat this 3 to 4 times a week now. Love it! Because I only make one portion, I end up using a whole banana, whoops 😅 Using the coconut oil with the peanut butter gives it a slightly more decadent flavor, and I’m full until 3 pm! Thanks for this 💕

    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!
