Baked apple oatmeal has all the comforting flavor you crave, with tender bits of apple and warming cinnamon in each slice. It tastes like apple pie, only not quite as sweet. Sprinkle some brown sugar on top before baking if you’d like a little extra sweetness.

Bake this recipe over the weekend as part of your meal prep routine and reheat individual portions for an easier morning. You’ll thank yourself later!

Ingredients You’ll Need

This baked oatmeal recipe is made with old-fashioned rolled oats, eggs, maple syrup, and your favorite milk. I used almond milk when testing this recipe, but any other milk should work, too. (Non-dairy milk or regular cow’s milk is okay!)

oats, applesauce, cinnamon, eggs, vanilla, and milk on a cutting board.

Paired with unsweetened applesauce, coconut oil, vanilla extract, and spices, you can quickly stir this together in one bowl. Feel free to add any extras you love, like raisins, chopped walnuts, or pecans. 

When it comes to the apple, choose a sweet variety like Pink Lady, Braeburn, Gala, Fuji, or Honeycrisp apples. 

Make Apple Cinnamon Baked Oatmeal

Preheat your oven to 375ºF and lightly grease an 8-inch square baking dish. Press a piece of parchment paper into the bottom of the pan if you want to guarantee easy removal later. (This is optional, though.)

In a large bowl, combine the rolled oats, cinnamon, baking powder, and salt.

Stir the dry ingredients together, then add in the wet ingredients like the applesauce, eggs, milk, maple syrup, vanilla extract, and coconut oil. If you don’t want any coconut flavor, use melted butter or olive oil, instead.

Stir well, then fold in the chopped apple. Add raisins or chopped nuts at this point, if you’d like to. Pour the oat mixture into the prepared pan and spread it out evenly. 

Bake at 375ºF for 40 minutes, or until the edges look golden and the center feels firm to the touch. Let the apple cinnamon oatmeal cool for at least 15 minutes before slicing into it.

Serve it with a dollop of yogurt or a drizzle of maple syrup, if you like.

Store any leftovers in an airtight container in the fridge for up to 5 days. Reheat a slice in the microwave for 30 to 45 seconds if you’d like to enjoy it warm again.

Frequently Asked Questions

What’s the texture of baked oatmeal like?

Baked oatmeal is firm enough to be sliced, but still moist in the center, almost like a muffin but with extra texture. You’ll be able to eat it with a fork, rather than a spoon. 

Is this recipe gluten-free?

Yes, when you use certified gluten-free oats. Oats are naturally gluten-free, but they can be contaminated during the manufacturing process, so it’s important to look on the label for a gluten-free label when needed. 

Can I use different spices?

Yes, of course! You can swap the cinnamon for an apple pie spice blend if you prefer. Or add in a pinch of ginger, nutmeg, or allspice if you like. 

Will honey work instead of maple syrup?

Yes, but honey tends to taste sweeter than maple syrup, so you may want to use only 1/4 cup in that case.

Notes

Nutrition information is for 1 of 9 slices made with cow’s milk and the optional raisins. This information is automatically calculated using generic ingredients, so it’s just an estimate and not a guarantee.
Gluten-Free Note: Oats are naturally gluten-free but can be contaminated during processing. Look for a “certified gluten-free” label on the package if you need a gluten-free recipe.
Vegan Note: If you need an egg-free recipe, you can swap the eggs for 2 flax eggs instead. This will make the baked oatmeal slightly more fragile to slice into, so just keep that in mind. Use coconut oil and a non-dairy milk to keep this vegan.

  1. I first made these with quinoa flakes, then oatmeal. The oatmeal version are the best! Just the right sweetness and the texture is delicious!

    1. I’ve made this slice several times now and I’m liking it more each time I make it. I have made a couple of small changes to ingredients; I cant get unsweetened applesauce ( only the sweetened one) so Ive backed the maple syrup to one tablespoon. I’m using safflower oil instead of coconut or butter (even though I know they’re tastier) as its a much healthier alternative.

  2. These were a hit with everyone in our family, especially our 6-year-old! We are vegan so I did flax eggs, and also left the oil out (personal preference), and they still turned out amazing. Will definitely be making these on a weekly basis!

    Side note: these worked great for a nut-free snack to pack in our kiddo’s lunch for school.

  3. I made this and loved it! Really great warmed up. I froze each piece separately and it’s wonderful when I don’t have time for breakfast.
