Healthy baked oatmeal recipe notes:
Overnight baked oatmeal
I love this baked oatmeal recipe because it’s super easy to whip up a batch once and enjoy it all week long. I recommend baking it and letting it chill overnight before serving for the best texture and flavor. Plus, then you will save yourself time making it in the morning!
How long can you keep baked oatmeal in the fridge?
This peanut butter banana baked oatmeal recipe keeps for about 6 days in the fridge, however it rarely ever lasts that long in our house!
Can you freeze baked oatmeal
I have had readers report freezing and reheating this baked oatmeal recipe with great success! I recommend wrapping the peanut butter baked oatmeal into individual servings and freezing it. That way, when you want to grab a slice to go you can simply take out one portion, heat it up and head out the door!
Peanut Butter Banana Baked Oatmeal: Substitutions
As always I get many questions about substitutions! So here are a few swaps you could make in order to ensure that this peanut butter banana baked oatmeal fits your dietary needs!
- Quick Cooking Oats: I find this recipe tastes the best when quick-cooking oats are used! If you only keep old-fashioned oats on hand you can easily toss them in your blender or food processor and pulse to achieve the same texture as their quick-cooking counterparts and then proceed to use them in this recipe!
- Peanut Butter: Any nut or seed butter can be used in place of peanut butter with fantastic results!
- Maple Syrup: Honey or any other liquid sweetener of choice can be used in place of maple syrup! Please {I beg you} to only use pure maple syrup if that is your sweetener of choice!
- Egg: As mentioned earlier a chia egg {1 TBS ground chia seeds mixed with 2 ½ TBS hot water} can be used in place of a regular egg to keep this peanut butter banana baked oatmeal vegan!
- Almond milk: Any non-dairy milk can be used in place of almond milk! If you do not need to avoid dairy you may also use regular milk!

Simply out of this world.!!! Wow, what a treat. I only had rolled oats and the bars turned out super- yummy.
Laura
I LOVELOVELOVED this recipe! It is super macro-balanced and it’s the perfect little afternoon treat with my coffee. I will definitely be making more soon!
Laura
Thank you Laura! It’s one of our favorite breakfasts!

I recently decided to cut out all kinds of sweeteners from my diet relying on dried fruits and esp dates. And guess what? I subbed the maple syrup with equal amount of dates. Gosh it was equally delicious, moist and now I was no longer guilty of having a second piece. Only I added at least 6T of hot water to the chia seeds, waited for it to fluff up & put all the wet ingredients , including the chopped dates and bananas into the processer, and they turned out real smooth and creamy. I increased baking time to 28 mins.
This recipe definitely needs a 10. 😋 A must try for everyone. Thanks So Much.
Laura
Thank you Meena! So glad you enjoyed it!
Alison Garcia
I made these and they’re really good! I used only 2 tablespoons of maple syrup because I’m trying to watch my sugar, and they had just the right amount of sweetness. I like that you can adapt it to the ingredients you have on hand.
Jenna Hall
Do you know how to modify this for a 9 x13 baking dish?
Laura
Hey Jenna! I would double the recipe and check at the suggested baking time. However I would imagine it could take 5-10 minutes longer to bake!
Shae
Your macros are off for this recipe as listed. Did you not include the peanut butter in your nutrition information?
Joyce
Hi, is there a way to replace the PB with PB2 powder?
Thanks!
Laura
Hey Joyce! If you wanted to use PB2 you would need to increase some of the wet ingredients!
Natasha
This was only my second time baking baked oatmeal but it turned out absolutely amazing! I love all things peanut butter banana and this was no exception. It came out a little on the mushy side which actually made it better because we don’t like our oatmeal too dry. I’m definitely making this again!!
Laura
I LOVE hearing that Natasha! I’m so glad you enjoyed it!
Erick
Recipe looks good. Not sure the nutrition facts calories add up though? I’m calculating calories at over 1700 with the ingredients listed.Cose to 200 cal per bar rather than 125. Does this seem more accurate? Thank you.
Tracy
I made these this morning and they are DELIC! I felt like I was eating dessert for breakfast. I opted not to put the peanut butter on top, but the flavor still came through beautifully. I also cut 6 squares, ate one for breakfast, and used the rest to meal prep. I will definitely be making these again!
Breck
This recipe was delicious. I usually have to tweak every recipe I find online, but this one was perfect from the get go. Even my picky husband loved it, and he hates oatmeal.
Kristyn
I made this last week for my 3 boys for breakfast. I used 2% cow’s milk, and stirred in some hemp seeds for add protein. I warmed it up in the morning and poured a small amount of cream on top, and sprinkled it with cinnamon. They loved it. I have more in the oven tonight using coconut milk instead of cow’s milk. Very easy recipe, and very easy breakfast for 3 boys on a school day! Thanks!
Megan
I’ve tried a lot of recipes for baked oatmeal and it seems like they often come out gummy or flavorless, so I keep coming back to this one! It’s delicious and the texture is fluffy and perfect. I love that I can keep it in the fridge and just pop a slice in the microwave for a quick and healthy breakfast. I do find that if I use very ripe bananas they make the oatmeal plenty sweet for my taste so I omit the maple syrup in order to cut the sugar content.
Meena
Simply out of this world.!!! Wow, what a treat. I only had rolled oats and the bars turned out super- yummy. I used chia seeds, and it needed more hot water. Final presentation, I sprinkled some raisins, chopped pecans and raw sunflower seeds. Ridiculously simple recipe with amazing results. Thank you!
Becky Blad
This is a great quick breakfast since it can keep in the fridge. I like to serve it in a bowl and add milk. Thanks for a great recipe!
Laura
I love the idea of adding milk! My oldest likes her oatmeal on the moist-side!
