The BEST 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!

Ingredients Needed

Ingredients measured out to make Peanut Butter Oatmeal: chia seeds, peanut butter, sea salt, cinnamon, oats, non-dairy milk, banana and water.

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.

How to Make Peanut Butter Oatmeal

Ingredients for peanut butter oatmeal (rolled oats, chia seeds, peanut butter, banana, milk and cinnamon) in a pot.

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

Cooked peanut butter oatmeal in a pot with a wooden spoon.

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

Can I use quick oats instead of rolled oats?

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.

How do I prevent the oatmeal from sticking to the pan?

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.

Can I make overnight oats with this recipe?

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.
