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 the 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.

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!

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

  1. 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!

  2. 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!

  3. 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!

  4. 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!

  5. 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!
