Apple Cinnamon Baked Oatmeal

This apple cinnamon baked oatmeal is inspired by traditional Amish baked oatmeal and studded with apples, raisins and loads of cinnamon flavor. It’s vegan, gluten-free and great for meal prep.

I’ve said it before and I’ll say it again… baked oatmeal is the best thing since overnight oats! I’ve been on a baked oatmeal kick this year and I’m so glad you’re just as obsessed as me because that means I get to keep trying and sharing new flavor combinations.

Each month, I’ve been making a seasonal baked oatmeal flavor and this month we’re going with apple cinnamon. Late September is the start of apple season so the timing is perfect. Head to a local apple orchard or grab some fresh apples from your local market and whip up this delicious apple cinnamon baked oatmeal.

This apple baked oatmeal is inspired by one of my favorite seasons: fall! I love visiting apple orchards and creating alllll the apple recipes. My ideal weekend would involve a cool, crisp morning, a cozy sweater and some sort of baked apple treat.

Who Invented Baked Oatmeal?

Since my obsession with baked oatmeal, I’ve been determined to figure out who invented baked oatmeal. I’ve yet to find the answer, but a lot of the old baked oatmeal recipes I’ve found come from the Amish, who made baked oatmeal to fuel their long days working on the farm.

Most of the Amish baked oatmeal recipes involve apples, raisins, and cinnamon so the recipe I’m sharing is inspired by that flavor combination, but without the butter, eggs, and milk! We’re keeping things vegan and dairy-free for my version!

I’ve made a similar version before with steel-cut oatmeal, but this version is just as a tasty and cooks up a bit faster. Here’s the apple cinnamon baked steel-cut oatmeal recipe, if you’re interested.

Ingredients in Apple Cinnamon Baked Oatmeal

  • rolled oats
  • unsweetened applesauce
  • milk – I like using unsweetened vanilla almond milk but you can use whatever milk you prefer!
  • apples and raisins
  • flaxseed
  • maple syrup
  • coconut oil 
  • spices and misc cinnamon, baking powder, vanilla extract, sea salt

How to Make Apple Baked Oatmeal

Baked oatmeal is pretty much just a matter of mixing and baking. Nothing fancy! In a large bowl, start by mixing together the rolled oats, cinnamon, baking powder, salt, almond milk, flaxseed, unsweetened applesauce, maple syrup, coconut oil, and vanilla. Fold in the raisins and diced apples.

Pour the mixture in a prepared baking dish, top with a few extra apple slices and bake at 375ºF for about 40 minutes or until the center is set.

This apple cinnamon baked oatmeal recipe is absolutely delicious with a drizzle of almond butter, a splash of almond milk, or maple syrup on top.

You can prep the baked oatmeal in advance and store in an airtight container for 4-5 days in the fridge. It’s such an easy meal prep option!

Ingredients

  • 2 cups rolled old-fashioned oats

  • 1 Tablespoon coconut oil 
  • 1 teaspoon vanilla extract
  • 1 cup diced apple, divided
  • 1/2 cup raisins

  1. Preheat oven to 375°F. Spray an 8×8 baking dish with non-stick spray.
  2. In a large bowl, mix together rolled oats, cinnamon, baking powder, salt, almond milk, applesauce, maple syrup, flaxseed, coconut oil and vanilla.
  3. Fold in raisins and 3/4 cup of the diced apples.

  1. I’m loving this recipe I need something easy like this that I could make I take a can of apples and put that on top I didn’t have regular apples but I did want to test if Apple’s I had to substitute for the maple syrup I had to use honey because I have some time I have a sugar attack early in the morning when I get up so I have to have something that’s not going to Spike my sugar up

  2. Ok, this is seriously delicious. This has been my meal prep breakfast for 3 weeks now and I haven’t gotten tired of it yet lol! It’s delicious without needing any extra maple syrup on top 😋

    Question: Can I add protein powder to this recipe? Would I need to adjust any of the ingredients? TIA!

    • Ahh yay! That makes me so happy to hear, Erin! So glad you’ve been loving this recipe. You can add protein powder to this recipe. I’d start with 1/2 cup and you should be fine with the ratios as is, but you can always add a bit more liquid if you feel as though it needs some more. 🙂 Let me know how it turns out for you!

  3. Have just made this hopefully it will toast as amazing as it smells. First time I have made this

  4. Added a scoop of Coconut Milk Vanilla Yogurt on top of my serving. It tasted like dessert. Will definitely make again and again. So easy and so much flavor!

  5. Brittany,
    We LOVE your baked oatmeal! I discovered your recipes about a year ago when I was trying to find healthier breakfasts. Now I always have some baked oatmeal in the fridge and we have it almost every morning! My favourites are apple, blueberry, and peanutbutter banana. Thanks for being a great resource for healthy recipes!

    • Ahhh that makes me so happy to hear, Kaleigh!! I’m glad you guys are loving all the baked oatmeal recipes. Thanks for coming back to leave a comment + star rating. It means the world to me. <3

  6. I mixed this up yesterday and it turned out rubbery and gummy. Should this be drier or soft? I was a bit disappointed in the texture but the flavour is great.

    I was using coconut milk as I’m dairy free. Do you think that makes a difference?

  7. Delicious recipe loved by all the family. Great warm for breakfast or cold as a snack on the go.

  8. Oh my gosh, Brittany… just made this oatmeal bake this morning and it was absolutely amazing!!!! It tastes almost like an incredible bread pudding kind of situation. My husband (who doesn’t typically like anything healthy lol) couldn’t stop raving about it and literally said, “Ok, you HAVE to save this recipe. THIS is a winner!”
    Note: I didn’t have everything on hand so instead just used what I did have (#covidbaking): 1/2 an apple, yogurt in place of applesauce, omitted coconut oil, and soda water in place of baking powder (thank you, internet, for sub suggestions lol).
    Amazing recipe – will definitely repeat a ton! : )

  9. Amazing recipe and super easy to make. Gave me a little taste of home while I am away at college. Thank you so much!

    Note: I used quick oats and it decreased the cooking time by about 5-10 minutes.

  10. Hi Brittany,

    This was delicious!
    However, I made few changes to your original recipe.
    I basically used what I had in hand: dates instead of raisins, banana pure instead of applesauce and oat milk.
    Many thanks for this

    I had two squares with oat milk and cinnamon 🙂

  11. Delicious! Loved this recipe. Husband added milk to his and I drizzled almond butter on mine. So good – great way to start the day. Thanks for the great recipes!

    • Ahh that makes me so happy to hear, Michele!! So glad this baked oatmeal was a hit. Thanks for taking the time to come back and leave a comment and star rating. I really appreciate it. <3

  12. I’ve been making Brittany’s baked oatmeal recipes for breakfast prep this past month. This apple cinnamon recipe is by far my favorite! Healthy, easy to prepare and it keeps very well throughout the week. I add a big dolop of peanut butter and stick it in the microwave and its an AWESOME breakfast every time.I’m heavy handed with the apple / raisin ratio but you cant have too many!

    • Ahh this makes me so happy to hear, Jay!! I’m glad you’re loving the baked oatmeal recipes. Thank you so much for taking the time to come back and leave a comment + star rating. It means the world to me. <3

  13. I made this recipe during apple picking season, and meant to post a review. DELICIOUS! Easy to make, healthy, and tastes like autumn any time of the year. 🙂

  14. I love this recipe. I make this one and rotate with other baked oatmeal recipes from EBF every single week. It’s such an easy meal to prepare and it’s wonderful for eating throughout the week. I have gotten so fast at making it that I shortly put it in the oven after it’s done preheating. I started making this when I was out on maternity leave and continue to do so now that I am at work. I never get tired of it!

  15. This was so delicous! However, I live with many gluten-intolerant people, and I was wondering how I could make this gluten free so I can share the yummy-ness with everyone!

    • Hey Scarlett – Oats are naturally gluten-free, so this recipe is already GF 🙂 But, if the people you live with have celiac disease or an intolerance to gluten, I would make sure to get certified GF oats to ensure there is no cross contamination.

  16. I made this this morning and used unsweetened oat milk. It was easy and quick and so delicious. I will be making this again and try fruit variations. Thank you.

  17. This is my go to breakfast! It is so easy, and so delicious! I make it the night before and let it set in the fridge and throw it in the oven when I’m getting ready in the morning! It works perfect!

  18. Your baked oatmeal recipes are AMAZING!! I’ve tried them all and I can’t even pick a favorite… they are all SO good, AND super easy to make!

    • Ahh that makes me so happy to hear, Jill! So glad you’re loving all the baked oatmeal recipes. Thanks for trying them all and for coming back to leave a comment and star rating, I so appreciate it. <3

  19. So, so delicious! I’ve just been eating plain oatmeal but this is a total game changer- especially with some peanut butter drizzled on top. I will definitely be keeping this recipe in my household. Thank you for sharing it!

  20. I love this! I leave out the raisins bc I’m not a fan, and I replace the maple syrup with honey. This time I added some pecans on top and drizzled honey almond butter on top! Great to make ahead of time and portion out for breakfast during the week!

    • Hi, im from Mexico! I have a conventional mini oven and i baked the recepie for 1 hour and the consistency and texture is still very runny i cant cut it, its like puddin, not like cake, i followed the recepie closely, do you think i should bake it more time? Or make the batter thiner in a bigger baking dish so it cooks better?´
      Thank you

  21. Can this be mixed the night before and baked the next morning? I have the ingredients to make it for breakfast for a group tomorrow. I’m excited to try it! 🙂

    • Hey Leslie! Yes, you can totally do this, but I recommend combining all the dry ingredients in a bowl and combining the wet ingredients in a separate bowl the night before. The morning of, simply mix the two together, pour into your baking dish and bake! The oats tend to soak up quite a bit of the milk overnight (kind of like overnight oats). If you don’t have a choice and need to fully prep the oatmeal bake ahead of time, that’s fine. It might just seem a little bit drier than normal after baking. If this happens, just serve with a splash of milk. Let me know how it turns out for you!

  22. This is sooo good!!! In one week I already made two batches! We went apple picking so I am thrilled about using up those apples! Am planning on shredding the apple next time so my 11-month old can eat some too! Thanks so much!

    • Oh yay, I am so happy to hear that you’re enjoying this recipe! I love the idea of shredding the apples. Thanks so much for coming back to leave a comment and star rating. I so appreciate it, Brianna!

    • Woo!! This makes me so happy, Jema. And thank you for coming back to leave a comment and star rating on the recipe. This feedback is super helpful and the star ratings help make my recipes visible to more people! <3

  23. Loving your baked oatmeal recipes! I just made the apple one today and will enjoy this week. I make a full size, eat it for two days and freeze the rest. They freeze very well. I know your hands will be full soon, but I’m requesting a pumpkin oatmeal bake from you!

    • Ahh! I’m so glad that you’re loving the baked oatmeal recipes, Sarah. And thank you for coming back to leave a comment and star rating on the apple cinnamon baked oatmeal. It’s super helpful and means so much to me. In terms of the pumpkin baked oatmeal, it’s like you read my mind. I already have it planned for October. I love that these baked oatmeals can be frozen too. I’m planning to make some to freeze before the baby arrives.

  24. Made this and LOVED it- will be making it again in the near future- it was so delicious with the apples and raisins. Thanks for this recipe!!

  25. Absolutely delicious!! The kids love it, it’s super easy and now I can’t wait to make the other baked oatmeal recipes!! I love so many EBF recipes. I can go there any day of the week, anytime of day and find a perfect recipe!

  26. I’ve always loved oatmeal, but this takes it to a whole new level! I made it for my mom today, and she loved it! Thank you for creating such delicious and healthy recipes! I love how dedicated you are to ensuring people feed their bellies and their souls with the good stuff!

  27. This past weekend, I’ve viewed this recipe so many times because of how great it looks and sounds! I’m planning to make it soon and love that incorporates seasonal produce, like apples, which are ideal this time of year!
