Peanut Butter and Banana Baked Oatmeal-3705

This Peanut Butter and Banana Oatmeal Bake is probably as close as I am going to get to making a back to school recipe.  I’ve been out of school for quite some time and have no intention of going back and I don’t have any kids yet.  Well, I do have Cheeto but he is already so smart he doesn’t need to go to school :)

And honestly, I kinda hate school.  I was that kid who always cried on the first day of school.  I’m pretty sure I cried everyday for the first month of 1st grade and 2nd grade probably wasn’t much better.  Back to school meant that the freedom of summer was over and that it was going to be a very long time before it was back.  It almost meant mean teachers, lots of homework and only getting to play outside for a limited time each day.

Peanut Butter and Banana Oatmeal Bake Steps

I know that there are kids out there that love school and might even look forward to the first day of school, but I certainly was not one of them!  Even now when I see the school buses picking up kids my stomach tenses up and I get a little bit nervous.  But mostly I’m thankful that I don’t have to get on that school bus!  

But, if you do have to go to school you might as well get to eat a delicious breakfast that is fast and filling!  I made my first oatmeal bake last year with this Ginger Peach version and I was amazed at how easy it was to make and how nice it was to just grab a slice and go every morning.  Peanut butter and bananas are one of my favorite flavor combos so  I knew this one would be a winner too!  It is kind of like a mixture between an oatmeal bake and banana bread with some peanut butter thrown in and makes my mornings much brighter!

    Cheeto is waaay to smart for school, haha! And that’s so cute you were the sad kid when school started. I was the annoying girl who loved school. Well, at least until high school when I was over it. This oatmeal bake looks delicious. And I am OBSESSED with these pictures Izzy! The background is so pretty : )

    • She Likes Food says

      Lol, I was the sad shy kid who just wanted to go back home, lol! When I have kids someday I hope to teach them to be more like the annoying girl who loved school, lol! Because it can be terrible if you don’t like it! Thanks so much, Natalie! :)

  2. says

    haha I never do well with the back to school recipes! It’s just us and Emma right now so I never even think about it! Although Emma the beagle would be happy to eat any food we put in front of her! :)

    This oatmeal sounds so good! Peanut butter and banana go so so well together!

    • She Likes Food says

      I never think about them either, Ashley! Lol, I’m sure she would! Cheeto is kinda picky but he does love string cheese which is kind of back to school-y!

  3. says

    I hated the first day of school, but I would’ve loved it if this were waiting for me for breakfast! I love baked oatmeal, and the peanut butter-banana combo is one of my favorites! :)

    • She Likes Food says

      I’m glad I’m not the only school hater, lol! I still have nightmares about the first day of school! Baked oatmeal makes lots of things better though :)

  4. says

    This is definitely a great back-to-school recipe! I actually never used to like oatmeal much, but as I get older, the more I like it. This peanut and banana version sounds delicious! I wish I could dive right into this for breakfast!

    • She Likes Food says

      I ate so much oatmeal as a kid that I got kinda sick of it too, but oatmeal bakes are so much better than the regular mushy stuff, lol! Thanks Gayle :)

  5. says

    Being homeschooled all my life, I would just laugh when I saw a school bus go by and think “glad I’m not them!” LOL. Now since I’m going to college I guess I’m joining the ranks of everybody else. Haha! This baked oatmeal would be a perfect crazy weekday-morning breakfast for me! I definitely need more of these easy ones up my sleeve! ūüėČ

    • She Likes Food says

      That is hilarious, Sarah!! It really was no fun having to leave the house and get on that bus every morning! I hope culinary school is so much fun! I can’t wait to hear about it!

  6. says

    I love school and learning!! I can’t get enough…. now. But when I was a kid, I went through phases. Loved school when I was little, only wanted to socialize though, through middle and part of high school.. then got serious towards the end and learned how much I loved it! So I’ll take your back to school oatmeal bake and make it all year round! This is delicious, Izzy! Pure comfort food! Have a fabulous weekend!

      haha, I think I might like school a little bit more now, but I was so shy and just hated being there! I hope you have had a great weekend, Traci!! :)

      Too cook for school too, lol! I think you would love oatmeal bakes, Denise! They are so nice for having a filling breakfast without having to cook anything! Thank you :)

    • She Likes Food says

      Hi Katie! I think it would still taste great! It just wouldn’t be as sweet, but breakfast doesn’t need to be good to be sweet :)

    • She Likes Food says

      Hi Victoria, I haven’t experimented using steel cut oats with this recipe so I can’t say for sure, but I’m thinking you might need to experiment a little and maybe add a bit more liquid and cook it longer until the oats are cooked through.

  7. Darcy says

    This is in the oven right now. I added some mini chocolate chips, being a chocolate addict. Can’t wait to see how it turns out!

  8. Cassandra says

    I just made this and it is YUMMY! It also made my house smell like Cinnabon. I followed all directions and used dark brown sugar. Really spectacular. I will definitely bring to my next brunch potluck. Thanks!

    • She Likes Food says

      I just made this yesterday too! And the house did smell amazing :) I’m so glad you liked this! And, a brunch potluck sounds like so much fun!

  9. Gav says

    Hi Izzy found this receipe after desperate look for anything with p butter, honey and oats however have used fresh milk, just baking at the moment cant wait for them they really look delicious, here is hoping thanks

  10. Caitlin says

    How would I reheat these in the morning? Also, I don’t have any vanilla extract… Thinking I could add a titch more syrup for sweetness?

    • She Likes Food says

      Hi Caitlin, you could either re-heat in the microwave (quickest) or in the oven. I’m lazy and just eat it cold, but it would probably be better heated up! Yes, you can most definitely omit the vanilla and just add more maple syrup or brown sugar for the sweetness :)

  11. Fernando says

    Thanks for sharing . I’d like to ask you here in Brazil there is no maple syrup. Can I replace for honey? Thanks

  12. Mayra says

    I absolutely loved this recipe! I used honey instead of brown sugar and pb2 for the peanut butter and they were still delicious and easy! Thank you so much for posting! This is going to be our breakfast for the week

    • She Likes Food says

      I’m so glad you liked it, Mayra! I make it all the time and eat it for breakfast all week too! I’ll have to try it with the pb2 :)

  13. Lisa W says

    Can you use overripe bananas like you would in banana bread? That’s all I got and I want to make it tonight!

  14. Meredith says

    This was so delicious!!!…but suuuuuper wet. I even added a few minutes to bake time but it didn’t help. Any idea why or how to get a drier consistency next time? Also, do you have the nutrition information?

    • She Likes Food says

      Hi Meredith, unfortunately I dont have the nutritional info nut there are few websites you can go to to calculate it. Hmmm, not sure why it was so wet, Ive never ran into that issue. Were all ingredient measurements and oven temp correct? You could try using less milk and see if that helps. Sorry about that!

  15. Pat Pasteur says

    Love this, I would eliminate the coconut sugar and add 1 cup semisweet chocolate chips.
    Great for breakfast, thanks for sharing!!

  16. Gina Godewyn says

    This is my favorite baked oatmeal recipe. I’ve made it several times. I always make it in muffin tins so it’s portioned out for breakfasts, and then I throw them in the freezer :)

    • She Likes Food says

      That’s so nice to hear, Gina! I’ve been baking it in a muffin tin lately too, I love the individual portions!

  17. Carol says

    Love this recipe and have adapted it in many ways for fun/variety. I would be embarrassed to tell you how often I make it. Almond butter works great and adding your favorite protein powder works too! I often freeze portions too.

    • She Likes Food says

      I’m so glad you are loving it, Carol! Haha, I do the same thing with adapting it and making other fun combos! I love the idea of adding almond butter in, I will have to try that soon! :)
