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 cinnamon 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 oats, but this version is just as tasty and cooks up a bit faster. Here’s the baked steel cut oatmeal recipe, if you’re interested.
Ingredients in Apple Cinnamon Baked Oatmeal
- rolled oats – makes for a super creamy bowl of oatmeal and are my personal favorite! Make sure you grab certified gluten-free if necessary. I like Bob’s Red Mill Gluten Free Whole Grain Rolled Oats.
- unsweetened applesauce – make your own homemade applesauce or use store-bought. Just make sure it’s unsweetened if you go that route.
- non-dairy milk – I like using unsweetened vanilla almond milk. You can also make homemade almond milk using my recipe. You can use whatever milk you prefer!
- flaxseed – flaxseeds are great sources of healthy fats, fiber and even plant-based protein!
- maple syrup – one of my preferred natural sweeteners. You can totally skip this or use another liquid sweetener like honey or agave.
- coconut oil – gives the baked oatmeal a nice moist texture.
- baking powder – rising agent that helps lighten the texture of the baked oatmeal. It prevents it from becoming too dense or heavy.
- vanilla extract, cinnamon and sea salt – to enhance the flavors!
- apples – you’ll need about 1-2 apples, peeled and finely chopped into pieces.
- raisins – the perfect companion to apples and cinnamon!
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 into 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.
Can You Make Baked Oatmeal Ahead of Time?
Yes, you can totally make baked oatmeal ahead of time, and that makes it perfect for meal prep! There are a couple of options that work really well.
Option 1: Bake and Then Reheat Before Serving
- Prepare baked oatmeal as the recipe suggests. Once baked, let the oatmeal cool, then cover the baking dish and place in the fridge. You can do this 1-2 days in advance. When ready to serve, take oatmeal dish from fridge, cover with foil and reheat in a 350°F oven for about 20 minutes. For individual portions, set toaster oven to 350°F and bake for 5-10 minutes or reheat in the microwave for 1 minute.
Option 2: Prep as Much as You Can Without Baking
- Mix together your dry ingredients in a bowl, cover and let sit out on the counter until morning.
- Mix together all the wet ingredients in another bowl, cover and store in the fridge until morning.
- In the morning, simply mix the wet and dry ingredients together, pour oatmeal mixture into your prepared baking dish and bake as recipe suggests.

This baked oatmeal is soooo good! I replaced the vegetal milk by 1% milk, flax seeds by chia and vanilla extract by rum extract (yum!) the result was really delicious 🙂 The raisins bring a little sweetness, the apples weren’t overcooked and the cinnamon was on point! 🙂 Thanks again for your fantastic recipes
