Apple Cinnamon Oatmeal Bake

This baked apple oatmeal recipe creates a light and moist chewy texture with crispy brown bites on top. Kind reminds me of the texture of oatmeal cookies with moisture retained…and NOT, well, soggy oatmeal texture. Yay for that!

If there is one reason why I prefer this apple oatmeal bake over traditional oatmeal, it’s the texture.

In fact, I don’t love traditional oatmeal because I cannot handle that mushy texture. The texture in this apple oatmeal bake reminds me of the textures of overnight oats – the rolls oats is soft, retaining its chewy texture, but not mushy and soggy.

Whenever I make these baked oatmeal with apples, I usually reheat and eat it for the next few days. Top it with a little maple syrup for some extra sweetness if you like, and maybe even a dollop of whipped cream…yum yum yum.

It reminds me of a less sweet, much healthier version of dessert. Wow, I just basically described the best breakfast ever – dessert for breakfast, with much less sugar! 🙂

These baked oatmeal with apples has raisins in them, but dried cranberry can be substituted in place of raisins. And I always get requests from readers to omit raisins and/or cranberries…which is totally fine!

Another lovely thing about this baked apple cinnamon oatmeal recipe is that it is so very versatile.

If you are looking for a healthy breakfast option especially during the Fall (but really I make this year round), this Baked Apple Oatmeal is it.

If you and your family are anything like us, prepare to make this over and over again.

Ingredients

Here are the key ingredients that make up this delicious oven baked oatmeal with apples:

apples – Any kind of fresh apples work well for this recipe. Make sure to dice them into smaller bite size pieces. I like to peel the skin but if you want to keep the skin on, go for it! There are a lot of nutrients on there, I just prefer the skin-off texture.
raisins – You can substitute with cranberries or any other dried fruit. You can also omit it if you don’t care for it. I love my apple oatmeal bake with raisins in it because it adds moisture and sweetness to it.
rolled oat – also known as old fashion oats, it is the most common type of oats used in most recipes out there. Quick oats can also be used.
ground cinnamon – This is a key ingredient that brings out all those delicious Fall flavors.
milk – any kind of milk can be used, even non-dairy milk.
egg – this will help the oats stick together and not crumble apart too much.
vanilla extract – use pure vanilla extract for best flavor.
brown sugar – this gives our baked oatmeal a nice rich flavor along a little sweetness…you won’t even need maple syrup for your final product!
baking powder – a leavening agent that will give our baked apple oatmeal a light and airy texture.

How to Make Baked Apple Oatmeal

Baked Apple Oatmeal is an easy and quick recipe ready under 10 minutes of prep and 40 minutes in the oven.

Start by greasing a 9′ x 9′ (or similar size) baking dish. We want to do this so that you’ll be able to remove the baked apple oatmeal easily from your baking dish when it is ready.

Next, bring together wet ingredients (melted butter, milk, egg and vanilla) in a medium mixing bowl. Whisk until a slightly fluffy.

Add dry ingredients (oats, baking powder, cinnamon, brown sugar, and salt) into the mixture.

Mix well to combine.

Add diced apples and raisins to the oatmeal mixture, then fold to combine.

Pour the mixture into the greased square (9′ x 9′) casserole dish, spread it out evenly and gently press the mixture down.

It will look a bit liquidy to start with (it solidifies as it bakes in the oven) but the oats will soak up the majority of the liquid mixture when baking.

Send baked apple oatmeal into the oven to bake at 325℉ for 35-40 minutes, or until oatmeal is set and liquid is completely absorbed.

Cook until the tops of the oatmeal are browned. Insert toothpick into the center of baked oatmeal to test for doneness – toothpick should come out slightly moist but not overly wet.

Let baked apple oatmeal cool for a few minutes before digging it.

Top with more milk, apple slices, or if you want a little sweetness, drizzle some maple syrup on top.

As you enjoy this delicious oatmeal bake, you’ll find hidden bites of sweet raisins and soft, flavorful apples along with the chewy oatmeal that is packed with hints of cinnamon flavor.

This one of my favorite things to cozy up with on a cooler day…it warm my heart and my tummy!
