The Ingredients You’ll Need to Make Baked Apple Cinnamon Oatmeal
Old fashioned oats: if you have a gluten sensitivity or allergy be sure to grab certified gluten free oats.
Eggs: these help bind everything together so you can get a delicious slice of baked oatmeal.
Almond milk: I love the neutral flavor of almond milk in this recipe but cashew, coconut, or oat milk would also work well.
Unsweetened applesauce: using unsweetened applesauce allows you to better control the sugar content in the baked oatmeal.
Maple syrup: for a little sweetness, this recipe uses maple syrup which works well with all of the other warm and cozy flavors in the oatmeal. You could also use honey if you prefer.
Melted butter: this adds a little extra richness and great flavor to the oatmeal.
Fresh apple: fresh diced apple chunks help to give this oatmeal even more texture and apple flavor.
Spices & Vanilla extract: warm spices and vanilla extract are a must in this baked oatmeal.
How to Make This Recipe
Step One: Start by preheating your oven to 350 degrees and spray a 9×13 baking dish with a little oil or non-stick baking spray.
Step Two: To a large mixing bowl, add the eggs, almond milk, apple sauce, maple syrup, melted butter, and vanilla extract. Whisk all of the wet ingredients together until well combined.
Step Three: Next, add the gluten free oats, baking powder, ground cinnamon, and salt to a separate mixing bowl and stir the dry ingredients until well combined.
Step Four: Next, fold the dry ingredients into the wet ingredients until you have a well mixed batter.
Step Five: Lastly, fold the diced apples into the batter until well combined.
Step Six: Transfer the baked oatmeal batter to a greased 9×13 baking dish. Bake the oatmeal at 350 degrees for 25-30 minutes until the oatmeal is just set.
Step Seven: Serve the baked oatmeal with a drizzle of icing if you like or almond butter and Greek yogurt.
Delicious Baked Oatmeal Mix-Ins
- chopped nuts – walnuts, pecans, or sliced almonds would all work really well in this recipe to give it even more texture and some crunch.
- fall spices – use a combination of your favorite warming spices instead of just cinnamon; you could use a teaspoon of apple pie spice or a blend of cardamom, ginger, and nutmeg.
- dried fruit – adding a handful of dried cranberries, raisins, or shredded coconut would all be delicious.
Frequently Asked Questions
Can I use a flax egg?
Yes! Several readers have reported that they have used flax eggs as a substitute in my baked oatmeal recipes with great results. You could also use you favorite egg replacement instead.
What can I substitute for butter?
Melted coconut oil or melted ghee will both work well as a substitute for melted butter in this recipe. If you’re feeling fancy you could swap the regular butter for brown butter instead.
Do I have to use dairy free milk?
No! Feel free to use regular whole milk if you prefer.
Can I use steel cut oats instead of old fashioned rolled oats?
No. For the best texture and results, I’d recommend using old fashioned whole grain oats or quick oats in this recipe, not steel cut oats.
How do I reduce the sweetness?
This baked oatmeal is pretty forgiving when it comes to the sweetness. I’ve actually made it without sweetener altogether at times and while it definitely is less sweet, the texture is not impacted at all.
If you would like to reduce the amount of sweetness in this baked oatmeal you can halve the amount of maple syrup or leave it out entirely.
Can I use another fruit instead of apples?
Sure! Feel free to use whatever fruit you like. I think pears would be a delicious substitute.
I don’t have applesauce, can I use something else?
If you like, you can use mashed banana but it will change the flavor of the recipe. I’d recommend making another one of my baked oatmeal recipes instead.
How to Serve Baked Oatmeal
There are so many delicious ways to serve this apple cinnamon baked oatmeal. Feel free to get creative with your toppings and other fun additions!
Here are a few of my favorites:
- drizzle on an easy glaze made with powdered sugar and almond milk
- add a dollop of Greek yogurt
- pour on a bit of maple syrup or honey
- sprinkle on extra cinnamon and fresh apple slices
Can I Meal Prep This Recipe In Advance?
Option One: Because the oats will soak up all of the liquid in the batter, I do not recommend prepping the batter in advance and baking the next morning. Instead, I find it more helpful to prep all of the dry ingredients and all of the wet ingredients separately the night before.
Option Two: The second option is my personal favorite which is to bake the oatmeal the night before and then reheat in the morning.
How to Store and Reheat Leftover Baked Oatmeal
- Store the baked oatmeal in an air-tight container in the fridge for 4-5 days.
- Reheat the baked oatmeal in the microwave for thirty seconds at a time until warm or in the oven at 350 degrees, wrapped in foil, until warmed through.
Can You Freeze This Baked Oatmeal?
Yes! To freeze the oatmeal, let it come to a complete cool and then transfer to a freezer safe storage container. You can reheat the oatmeal in the oven at 350 degrees wrapped in foil until warmed through or in the microwave.

I’ve never tried baked oatmeal before but I prepped this on a Sunday to eat during the week and it’s delicious. It reheats well. I used a bit less maple syrup and a whole cup of apple sauce like other reviews mentioned. Great with Greek yogurt and a little maple syrup on top.
I’m so glad you loved it, Tess!
This is the best recipe! I used peaches instead of apples and it was so good. I also only used 1/4 cup syrup and 1 cup apple sauce like another review mentioned and it was perfect sweet. This will be frequent breakfast in our home
so glad you liked it, Rachel!!
I’ve made this recipe at least 5 times now – it’s fantastic!
I use half the maple syrup and use a full cup of apple sauce. One of my favorite dishes to have on hand as breakfast or a snack for the week.
so glad you loved it, Liz!
I FORGOT TO GET ANY INGREDIENTS TO MAKE SOMETHING FOR BREAKFAST FOR THE WEEK, BUT I KNEW I HAD OATS AND APPLES, SO I MADE THIS WORK AND IT IS EASY AND DELICIOUS!!!!
Hello! I just wanted to say that I already made them a few times and I love them, but now I’m in trouble… My husband tried them and loves them. I guess I’ll need to cook them more often. It’s a good problem, they’re easy to make😅
My 3 year old and I whipped this up this morning and it’s delicious. Used half the maple syrup because we ran out and it was perfectly sweet. Live your recipes! They’re always a hit.
So happy y’all loved it, Emm!
This was so easy and it tasted like fall. My son and I loved it. My husband doesn’t do oatmeal (texture) and he said, “if I liked oatmeal, I’d eat this in one sitting.” So, that’s something, too! I froze 1/2 will see how it thaws in a few weeks.
Made weekday breakfast so easy and delicious!! the perfect fall meal prep, especially now that its apple season!
This was so good! My husband loves baked oatmeal but I’ve never found a recipe I like until this one. Great texture and the flavor is amazing. Unfortunately my toddlers agreed—I was hoping this would give us a good 3-4 days of meal prep but they ate more than the adults so it won’t even last us two days! Super easy to whip up though so it’ll be super easy to add to our regular rotation.
This is delicious! I added some pecans and golden raisins in mine as well as topping with the icing glaze. *chef’s kiss*
We loved this recipe! I used honeycrisp apples and apple pie spice. I added some toasted pecans for a nutty flavor and more texture. So, so good! Thank you for the great recipe!
You’re baked apple cinnamon oatmeal is amazing!!! I don’t like oatmeal but this might convert me
This was wonderful! Easy to make, and much tastier and healthier than instant oatmeal. Thank you!
I loved this! A great and simple breakfast idea. I peeled and grated my apples, and added walnuts. Additionally, I cooked it another 15 mins to firm it up and cut it into squares for “take to work” breakfast. Love this website and your beautiful meals… can’t wait to cook more!
thanks for sharing, Sarah! happy you loved it!
Super delicious, served enough for breakfasts all week and was super easy for grab & go. Satisfying!
Tried this for the first time. Loved it! The apples were still a little crunchy but that was no problem. I eat a low or no sugar diet and I used half the maple syrup and it was plenty sweet. This will be on my regular breakfast rotation and next time I will eliminate the maple syrup. It was great cold the next day too!
This is so easy and delicious to make!! I actually was a half cup short of the oats and it still turned out great!
This was quick and easy to make and it came out perfectly. I used half agave and half maple syrup, but followed the recipe otherwise. I love that I already had everything I needed. I will definitely be making again for quick weekday breakfasts!
Really delicious and easy to put together. Tastes even better the next day! I added dried cranberries and walnuts and would definitely recommend that. Might also use more spices next time because I love cinnamon. Super tasty and will absolutely be in my fall rotation!
Made this tonight with some apples that needed to be used. So simple & delicious! We served it with a scoop of ice cream, but it’s going to be perfect on its own as breakfast this week.
This looks amazing and I want to make ASAP ha! I don’t have apple sauce or bananas on hand, but I have apple butter… could I use that instead?
Hi, Hailey! I think that could work, if the apple butter has a similar consistency to applesauce!
Can I make this with a flax egg?
Hi, Peggie! I cover this in the blog post. Hope you love the recipe!
