Apple Cinnamon Baked Oatmeal

Everyone has been absolutely loving our new Peanut Butter, Banana, Chocolate Chip Baked Oatmeal, so we decided to make another amazing version!

You CANNOT go wrong with apple and cinnamon baked in an oatmeal, right? This flavor combination reminds me of the little oatmeal packets I used to have when I was a kid, but of course cleaned up and using whole ingredients that I feel good about baking with and eating. It’s so easy to put together, using only one bowl and once it’s mixed together you place it in the oven and forget it. It’s perfect for breakfast, an after school snack or to bring along to a potluck.

  1. Pre-heat oven to 350 degrees and grease an 8″ x 8″ oven-safe dish. If desired, prepare a parchment sling by cutting out a piece of parchment paper slightly larger than the pan and placing it inside.
  2. In a large bowl add eggs and whisk to combine. Then almond milk, maple syrup, apple sauce, oil, and vanilla and whisk to fully combine.
  3. To the wet ingredients add oats, baking powder, chia, cinnamon, salt and grated apples and mix until fully combined.
  4. Pour into prepared 8″x 8″ dish and bake for 30-35 minutes, until the center is just barely firm.
  5. Scoop and serve warm as is or with almond milk, or cool and slice into 9 square portions.



We topped the oatmeal bake with a few pieces of diced apple. Reserve a small piece of the apple before grating if desired to top the oatmeal bake with.

  1. This baked oatmeal was so easy to make and is very delicious. I love all of your baked oatmeal recipes and make them regularly. They are the perfect nutritious breakfast dishes to serve to my family.

  2. I absolutely LOVE this recipe!!! I make it almost every week portioning it out into individual reheatable containers that I can have each morning.

    I’ve also tried this recipe swapping out the apples for frozen mixed berries (I like blueberries, blackberries, and raspberries), and it works perfectly for those without any other changes needed to the recipe (and a little faster to prepare).

    I recently tried adding some lemon zest to my berry version and it was like eating a (healthier) berry crumble, the only thing missing was some ice cream!

  3. Hi! I made this today and I loved it! I made a couple of changes to the recipe since I read that for some people the final product was a bit dry. I doubled the milk and the apple sauce. Also, I added ground flax and lowered the amount of chia seed. I used pumpkin spice instead of cinnamon. I really liked it!

    1. Hi Tara! Sorry you didn’t enjoy the final result. I actually ended up testing this recently and that wasn’t my experience with it at all, as the grated apples added quite a bit of moisture. Any chance your apples were on the small side?

  4. This looks so yummy! Is there a way to substitute the eggs in this recipe for something else? We have an egg allergy in our family. Thanks for all you do!

  5. I made this apple cinnamon oatmeal last night, I find it much drier than the banana chocolate chip and not too much flavor to it. Is there anything I can add to make it not so dry (maybe more applesauce?) and anything to add for more flavor?

  6. This is a new favorite in our house! It totally reminds me of a clean version of my favorite oatmeal packets growing up. The apple cinnamon was always the first to disappear 🙂

    To up the fiber, I left the skin on the apples and added 2 tablespoons of ground flax seeds. Next time I’ll try adding some collagen protein to the mix to add some extra protein. I did sprinkle the top with extra cinnamon, the smell of it baking had my hubby coming into the kitchen asking if I was baking apple pie. SO GOOD! I told him it was Lexi’s recipe (the one that came up with the best gluten free birthday cake) and he said, Thanks, Lexi! Lol

  7. Looks amazing! Wondering if replacing some of the oats with protein/collagen to up the protein content would be a possibility?
