Easy Cinnamon Sugar Baked Oatmeal - a healthier breakfast recipe! Baked oatmeal is a fast and easy breakfast - freeze it for fast mornings!

Post originally written in 2016, updated in 2019.

We got a new addition to our family for Christmas and I’m so excited to share the news with all of you. It’s a girl, and she’s adorable. You’re probably thinking a puppy or a kitten, but nope. Not a baby either!

For Christmas, I got an iRobot Roomba Vacuum. We named her Maude. And I love her so much!

Maude is such a super welcome addition to our family. She joins us and our dog, a Golden Retriever. If you have a dog – especially a golden – you’ll know why Maude’s arrival was like something from heaven. Every day Maude turns herself on, announces herself to the room, not unlike an actual child, and vacuums my entire downstairs. In fact, my floors are being cleaned right now and I am not having to do it.

While she’s cleaning I have more time to cook and bake!

Baked Oatmeal is one of my favorite easy breakfast recipes. It tastes sinful but it’s healthier and so much better than plain old cereal.

Maude and I are still getting to know each other. She’s not perfect, but hey, who is? Sometimes she runs for 10 minutes and then docks herself and I think, What the heck? Stay up too late and now you’re shirking your responsibilities? Or sometimes she gets so tired while trying to get unstuck from under the dining room table that I have to go rescue her. <–That one is pretty funny.

All in all though, that old gal and I are going to be BFFs. Move over Dyson, my robot is in town! (Seriously, if you’re considering adding a robot to your family, do it. She’s worth every single penny. But don’t tell her I said that. I think she’d be upset if she knew I bought her love.)

Plus, having something else vacuum for me frees up my time so I can do other things I love, like workout and create new breakfast recipes that I can enjoy as a second breakfast. I’m all about the second breakfast, as you all know. I’m not hungry at o’dark thirty when we have to leave for school and the gym so I just drink a quick smoothie, but I’m starving after. And while I’d love to live on banana bread (even the healthier kind), sometimes a girl has to eat her oatmeal.

This recipe is similar to the other baked oatmeal recipes I’ve made, one with blueberries and one that makes individual muffins. It’s one bowl, easy, no mixer, and you bake it. The texture is not like your normal oatmeal – I do not like regular oatmeal but I love it baked! It’s kind of like a soft granola bar when you bake it, and it’s not mushy at all.

Can you make oatmeal in the oven? Heck yes you can! It tastes so much better than regular oatmeal.

Warm from the oven this baked oatmeal is sweet and chewy and everything breakfast is asking for.

This recipe was meant to be kind of like snickerdoodles married oatmeal: the pan of oatmeal is sprinkled with some cinnamon sugar before baking. It’s still a pretty healthy breakfast though – there’s no oil and not much sugar baked into it. Slice and serve it with syrup (sugar-free, if you’re reducing that sugar intake) or just serve it with berries and/or some yogurt. Then, because it’s in bar form, you can slice it and freeze it for easy mornings.

How to make Cinnamon Sugar Baked Oatmeal:

  • I use regular old fashioned oats in this recipe, but you could use instant steel-cut (like I did here).
  • I use almond milk almost exclusively in my oatmeal, but you can use nonfat cows milk or any kind of dairy-free milk (like cashew or soy).
  • I used mashed banana in this version, but you can use an equal amount of unsweetened applesauce if you prefer.
  • Made as directed this recipe has only 135 calories per servings.

Enjoy this Cinnamon Sugar Baked Oatmeal as an easy breakfast. It’s delicious plain or with fruit!

  1. I’ve always wanted a Roomba! And Maude is a perfect name. She’ll be a very happy addition to your family. Usually additions take more work, but she’ll actually help. While you watch TV or nap. It’s amazing!
    Except, you know, when the robots and drones take over the world Terminator-style. 😉
    So baked oatmeal is  the only way to go. Otherwise it’s just too mushy. This looks perfect!

  2. Oh that vacuum sure does sound fun! As does this oatmeal…I love the cinnamon sugar flavor! It’s been way too long since I’ve made a baked version, so I’m loving this!

  3. YES. I had something similar to this at a cafe in Delaware (what?!?). And I have basically not been able to think of anything else since. I have to make this happen. 

  4. My brother bought one of those Roombas too, and he is a huge fan. He gets to set the time the vacuum cleans so his carpets and floors are clean by the time he gets home from work. Love this oatmeal – too bad the Roomba can’t make that for you too! 😉

  5. OMG I’m cracking up. YES to the rescues. We haven’t had a Roomba in years, but it was wonderful. I mainly used it in bedrooms, and I loved how it would get under those beds for me. Downside: it also picked up stray earrings, money, and bobby pins!
    I think i need to give this baked oatmeal a try, looks delicious!

  6. I love that you have Maude! I need a Maude in my life and now that I read about how good of a job she does, I’m going to research one!

    Baked oatmeal is so easy and you have breakfasts ready for a few days (or longer if you freeze some) which is great on school mornings! And as you said bikini season is just around the corner!

  7. We have an auto-vac too! My husband bought it last year with our wedding gift money, and we love it. Her name is Tina (short for Robotina, the Spanish-dubbed version of Rosie on the Jetsons) 

    Part of the reason I love it is that it makes life simpler….just like this oatmeal. Who wouldn’t want to wake up to a house full of cinnamon love? Especially if I don’t have to guard it over the stove, and can spend time getting ready instead. 

  8. I’ve heard such mixed reviews about the Roomba but you have me thinking about it again! Just like I’ll be dreaming of this delicious baked oatmeal!

  9. I have a dog, but he doesn’t shed! Nonetheless, I can COMPLETELY see the appeal of a Roomba- good to know they’re worth it! It’s always nice to have something to pick up after you (kinda reminds me of the vacuum in the Teletubbies, haha!) This baked oatmeal looks amazing- a delicious way to stick to my resolutions 🙂

  10. I totally thought you were talking about a dog.  I think I’d rather have the roomba though!  This baked oatmeal looks perfect for a healthy morning!

  11. I love baked oatmeal and so do my kids!  Oh how a robot vacuum would be awesome!!  6 kids are probably as bad as having a shedding dog 😉

  12. This looks great. I really like the part about slicing and freezing. And now you’ve got me thinking about a Roomba again. )

  13. I’ve never even heard of baked oatmeal but it looks sooo good!
    Great idea 🙂

  14. I have never tried baked oatmeal, but now I will!  And have you ever thought of spending your extra time watching RHONJ?  Very entertaining!

  15. Hahaha “if you’re considering adding a robot to your family”…omg we are so in 2016!! It’s kind of scary but I am totally jealous of your Maude…I HATE vacuuming! This oatmeal looks aaaaamazing! Perfect for a quick breakfast 🙂

  16. I love that you named your Roomba Maude! So funny and cute! I’m glad you’re enjoying the new addition to your family – I would too! 🙂 Also, this oatmeal looks wonderful! 😀

  17. I’m def an oatmeal person. I’ve never baked it before but it sounds amazing! This recipe is right up my alley. I’m so jealous you have Maude! I need one for my cats. 😮

  18. Haha Dorothy! I hope you and Maude are very happy together – as happy as I’ll be when I try this awesome oatmeal, yum! Happy New Year 🙂

  19. We have one too! We have a husky and a lab and the vacuum probably saved my marriage lol! 

  20. Snickerdoodles married oatmeal?? I love this!! haha. And I need to get me my own Maude, STAT. I really like the idea of kicking back with some baked oatmeal while watching a robot clean my house. She cleans the toilet too, right? Right??

  21. Yum! I love oatmeal, and I definitely prefer the kind you cook on the stove instead of the instant kind, but I’ve never tried it baked. This looks great and I can’t wait to try it! … and I’m glad I’m not the only one that names my cleaning stuff. I have a vacuum named Pete. 🙂

  22. WHY have I never made baked oatmeal before? This seems so much better than mushy old oatmeal. And we have a robot vacuum too, and its seriously life changing and the best thing ever. 🙂

  23. Hahaha!! We have an iRobot too! however, we never named it. My mom rarely runs it because, although it does a good job, it doesn’t clean in a very systematic way. Oh well! This baked oatmeal looks soooo good!

  24. I can’t decide which I love more – the baked oatmeal or Maude!  I can definitely get one of them into my life today…although now I really want the other one too!  🙂

  25. I made this for breakfast today and it was excellent. I was feeling super lazy so I mixed all the wet ingredients in the food processor and stired in the oats at the end. It worked pretty well! Will definitely make this again!

  26. Giving this yummy baked oatmeal a shot this chilly January morning. Hoping it tastes as good as it smells!!

  27. If you freeze this oatmeal, how long would you reheat it for? 

  28. Can you use Quick Oats? 

  29. This was wonderful!! We were a little skeptical at first, thinking it might be “dry and too chewey”. We were wrong!!! The texture is perfect, just chewey enough…..and the flavor is amazing! It feels like your adding too much vanilla and cinnamon but I followed the recipe and was I surprised. We sprinkled a few blueberries with it in our bowl and it was delicious. It was the perfect breakfast for a cold, crisp winter morning at the cabin, thank you so much for sharing this recipe. It will now be the only way we make oatmeal! P.S. It smells great when its baking! 😊

  30. Anytime I can get oats into me and my family, I try. This was a hit, everybody loved it and it was great leftover too! Reheated beautifully, and delicious.

  31. Do you know of any substitute for the banana? I try to eat low glycemic index/low carb. Oatmeal does ok, and I can use a brown sugar substitute, but bananas spike my sugar 😒
