Ingredients for Apple Cinnamon Baked Oatmeal
- 2 1/4 cups old-fashioned rolled oats, gives the bake its hearty, chewy texture
- 1 3/4 teaspoons ground cinnamon, the flavor backbone of this whole recipe
- 1 teaspoon baking powder, helps the oatmeal rise slightly so it isn’t dense
- 1/4 teaspoon salt, balances the sweetness so the bake doesn’t taste flat
- 1 3/4 cups milk of your choice, I like unsweetened vanilla almond milk for extra flavor
- 1/2 cup unsweetened applesauce, adds moisture and natural sweetness without extra sugar
- 1/3 cup pure maple syrup, my go-to sweetener, though honey or brown sugar work too
- 2 tablespoons melted butter or coconut oil, adds richness and helps everything bind
- 2 large eggs, beaten, holds the bake together so it slices cleanly
- 2 teaspoons pure vanilla extract, rounds out the warm spice flavor
- 1 cup diced apple, I always reach for Honeycrisp, but any baking apple works
- Optional toppings: whipped cream, yogurt, nut butter, extra maple syrup, or a dash of cinnamon
Note: this recipe serves 6.

How to Make Apple Cinnamon Baked Oatmeal Recipe?
I promise this recipe is as simple as it sounds. There’s no fancy technique here, just two bowls, one pan, and a hot oven. Here’s exactly how I put it together every time.
Preheat the Oven and Prep Your Pan
I always start by preheating my oven to 350 degrees F so it’s fully ready by the time my batter is mixed. While it heats, I grease an 8×8-inch baking dish with nonstick spray. This small step keeps the oatmeal from sticking to the corners once it’s baked and cooled.
Mix the Dry Ingredients
In a large bowl, I whisk together the oats, cinnamon, baking powder, and salt. Getting the cinnamon evenly distributed here means every bite has that warm, cozy flavor. I like to give it a good stir so there are no clumps of baking powder hiding in one spot.
Whisk the Wet Ingredients
In a separate medium bowl, I combine the milk, applesauce, maple syrup, melted butter, eggs, and vanilla extract. I whisk until it’s completely smooth, since a well-blended wet mixture makes the final texture much more even throughout the bake.
Combine and Fold in the Apples
I pour the wet mixture into the dry ingredients and stir until just combined. Then I gently fold in the diced apples with a spatula. I try not to overmix at this stage, since I want the apple pieces to stay intact instead of turning mushy in the batter.
Bake Until Golden and Set
I pour everything into my prepared dish and bake for 30 to 40 minutes. I know it’s done when the top turns golden brown and the center feels set rather than jiggly. I usually start checking around the 30-minute mark so it doesn’t overbake.
Cool Slightly and Serve
Once it’s out of the oven, I let it rest for about 5 minutes before slicing. This short rest helps the squares hold their shape instead of falling apart. Then I serve it warm with whatever toppings sound good that morning.
Additional Tips for Making This Recipe Better
I’ve made this apple cinnamon baked oatmeal more times than I can count, and I’ve picked up a few tricks along the way that make it even better.
- I always dice my apples small and even, so they cook through at the same rate as the oats.
- I let my eggs come to room temperature first, since cold eggs can make the melted butter seize up.
- I double-check my oven temperature with a thermometer, because an oven running hot can dry the bake out.
- I sometimes toast the oats lightly in a dry pan first, which gives the finished dish a nuttier flavor.
- I always let the dish cool for a few minutes before cutting, or the squares fall apart on me.
Common Mistakes to Avoid
- I overmixed the batter once after adding the apples, and it made the texture gummy instead of tender.
- I used quick oats instead of old-fashioned oats one time, and the bake turned out mushier than I wanted.
- I skipped greasing the pan once, thinking it wouldn’t matter, and I regretted it when serving got messy.
- I didn’t let the oatmeal rest after baking, and the first slice completely fell apart on the plate.
- I added too much liquid trying to double the recipe without adjusting properly, so I always scale carefully now.
How to Serve Apple Cinnamon Baked Oatmeal?
I like to cut this into squares and serve it warm, straight from the pan for a casual weekend breakfast, or plated with a drizzle of maple syrup and a dusting of cinnamon for something a little more special. A dollop of yogurt on top adds a nice tang against the sweetness, and it’s an easy way to turn this into a healthy apple oatmeal bake with yogurt for a more filling meal.
I also love topping it with a handful of chopped pecans for crunch, or thin apple slices fanned over the top for a prettier presentation when I’m serving guests. A small pitcher of warm milk on the side lets everyone pour a little over their own serving, which always feels like a nice touch at the breakfast table.
Variations
- Dairy-free: swap the milk for oat milk or almond milk and use melted coconut oil instead of butter.
- Sugar-free: skip the maple syrup and rely on the natural sweetness of the applesauce and a ripe apple.
- Higher protein: stir in a scoop of vanilla protein powder or a spoonful of Greek yogurt for a high protein apple cinnamon baked oats version.
- No applesauce: replace the applesauce with an extra half cup of mashed banana or an extra diced apple for an apple cinnamon baked oatmeal no applesauce option.
- Nutty crunch: fold in chopped walnuts or pecans right before baking for extra texture.
- Warm spice boost: add a pinch of nutmeg or cardamom alongside the cinnamon for a deeper spice flavor.
- Fruity twist: mix in a handful of dried cranberries or raisins with the diced apple. If you’re in the mood for another fruit-filled baked treat, you can also try this homemade peach pop tarts recipe or homemade cherry pop tart recipe for a different breakfast option.Â

Make Ahead and Storage
I make this apple cinnamon baked oatmeal ahead all the time, since it holds up so well in the fridge. Once it’s fully cooled, I cover the pan tightly or transfer squares into an airtight container, and it stays fresh for up to a week.
When I’m ready to eat a portion, I just pop it in the microwave for about 30 to 45 seconds until warmed through. It also reheats nicely in a low oven if I want to warm a few pieces at once.
If I want to freeze it, I wrap individual squares tightly and store them in a freezer bag for up to 3 months. I let them thaw in the fridge overnight before reheating for the best texture.

FAQs
Can I make a healthy apple cinnamon baked oatmeal version of this recipe?
Yes, I just swap the maple syrup for a smaller amount of natural sweetener and rely on the apple and applesauce for most of the sweetness.
Can I use quick oats instead of old-fashioned oats?
I’ve tried baked apple oatmeal with quick oats before, and while it works in a pinch, the texture turns out softer and less chewy than with old-fashioned oats.
Do I need to peel the apples first?
I usually don’t peel mine since I like the little bit of texture the skin adds, but you can peel them if you prefer a softer bite.
Can I double this recipe?
Yes, I double it often and bake it in a 9×13-inch dish instead of an 8×8, keeping an eye on it since it may need a few extra minutes in the oven.
How do I know when it’s fully baked?
I look for a golden top and a center that feels set rather than jiggly when I gently shake the pan, usually right around the 35-minute mark.
