I started making this Apple Maple Baked Oatmeal Recipe on the coldest mornings of the year, mostly because I wanted breakfast to feel like a hug instead of a chore. I mix everything in one bowl, slide it into the oven, and let the smell of cinnamon and baked apples fill my whole kitchen while I get ready for the day.
It’s become one of those recipes I lean on constantly, especially when I want something that tastes indulgent but is secretly pretty wholesome. If you’ve been hunting for a healthy apple oatmeal bake with yogurt on the side or just a cozy make-ahead breakfast, I think this one is going to become a regular in your house too.
Cooking Time
- Prep Time: 10 minutes
- Cooking Time: 35 minutes
- Total Time: 45 minutes
Ingredients
- 2 cups old-fashioned rolled oats — gives the finished bake a chewy texture, quick oats will turn mushier
- 1 teaspoon baking powder — helps the oatmeal set into more of a cake-like texture instead of staying dense
- 1 teaspoon ground cinnamon — brings the warm, cozy flavor that pairs so well with apples
- ¼ teaspoon salt — balances the sweetness and keeps the flavor from tasting flat
- 2 cups milk — any kind works here, so use whole, low-fat, or a non-dairy option depending on your preference
- 1 large egg — helps bind everything together as it bakes, skip it for a fully vegan version
- ⅓ cup maple syrup — this is the main sweetener, so use real maple syrup for the best flavor
- 2 tablespoons melted butter — adds richness, swap in melted coconut oil if you want it dairy-free
- 1 teaspoon vanilla extract — rounds out the sweetness and deepens the overall flavor
- 1 medium apple, diced — any variety works, though a firmer apple holds its shape better while baking
- ½ cup chopped walnuts — adds crunch and a classic pairing with apples, leave out for a nut-free version
Note: this recipe serves 6.
Equipment You Need
- Large mixing bowl — for combining your dry ingredients together
- Medium bowl — for whisking the wet ingredients before combining
- Whisk — helps blend the egg, milk, and maple syrup smoothly
- 9-inch square baking dish — the right size for even baking and a good texture throughout
- Butter or oil for greasing — keeps the oatmeal from sticking to the dish
- Oven mitts — for safely handling the hot dish once it’s out of the oven
How to Make Apple Maple Baked Oatmeal Recipe?
This recipe really doesn’t ask much of you, which is exactly why I make it so often on busy mornings. Everything mixes together in two bowls before it goes into the oven to bake. Here’s the process I follow every single time.
Prep Your Baking Dish and Oven
Preheat your oven to 375°F and grease your 9-inch baking dish with butter or a light coating of oil. This step keeps the finished oatmeal from clinging stubbornly to the sides once it’s baked. Set the dish aside while you prepare your ingredients.
Mix the Dry Ingredients
In your large mixing bowl, combine the oats, baking powder, cinnamon, and salt. Stir them together until they’re evenly distributed throughout the mixture. This ensures every bite has the same balanced flavor once it’s baked.
Whisk the Wet Ingredients
In your medium bowl, whisk together the milk, egg, maple syrup, melted butter, and vanilla extract. Whisk until the mixture looks smooth and fully combined, with no streaks of egg remaining. This forms the custardy base that holds the whole bake together.
Combine Everything Together
Pour the wet mixture into the bowl with your dry ingredients, then add the diced apple and walnuts. Stir everything gently until it’s just combined, being careful not to overmix. You want the apple pieces distributed evenly throughout the batter.
Bake Until Golden
Pour the mixture into your prepared baking dish and spread it into an even layer. Bake for 30 to 35 minutes, until the top turns golden brown and the center feels set when you press it gently. Let it cool for a few minutes before slicing and serving.
Additional Tips for Making This Recipe Better
I’ve baked this more times than I can count, and here’s what I’ve learned along the way.
- I always dice my apple into small, even pieces so it bakes through completely instead of staying firm in the middle.
- I like to toast my walnuts in a dry pan for a few minutes first, since it makes their flavor so much richer.
- I never skip greasing the dish well, because the edges are my favorite part and I don’t want to lose them to sticking.
- I sometimes swap half the milk for buttermilk, which gives the bake a slightly tangier, richer flavor.
- I let mine rest for a good five minutes after baking, since it firms up and slices much more cleanly that way.
Common Mistakes to Avoid
- I once used quick oats instead of old-fashioned, and my bake turned out mushy instead of having that nice chewy bite.
- I overmixed the batter one time trying to get it perfectly smooth, and the texture came out denser than I wanted.
- I forgot to dice my apple small enough once, and the pieces stayed too firm even after a full bake.
- I pulled mine out of the oven too early because I was impatient, and the center ended up wet and undercooked.
- I skipped greasing the pan one busy morning, and half my oatmeal stuck to the dish when I tried to serve it.
How to Serve Apple Maple Baked Oatmeal?
I like to serve this warm, straight from the dish, with a small pitcher of extra maple syrup on the side for anyone who wants more drizzle. A dollop of yogurt or a splash of cold milk poured right over a warm slice makes it feel extra comforting.
Scattering a few extra apple slices and a sprinkle of cinnamon on top right before serving makes it look a lot more special for a weekend brunch. If you’re building out a rotation of cozy baked breakfasts, this pairs beautifully next to something like a strawberry baked oatmeal for mornings when you want to offer a couple of flavors side by side.
Variations
- Swap the apple for pears for a slightly different, softer sweetness
- Use coconut oil and a flax egg instead of butter and egg for a fully vegan version
- Add a scoop of protein powder to the wet ingredients for high protein apple cinnamon baked oats
- Skip the added maple syrup and rely on the natural sweetness of the apple for a lower-sugar take
- Stir in raisins or dried cranberries along with the apple for extra bursts of sweetness
- Try baked oatmeal with maple syrup swapped for honey if that’s what you have on hand

Make Ahead and Storage
You can prep this the night before by mixing the dry and wet ingredients separately and storing them covered in the fridge, then combining and baking fresh in the morning for an overnight baked apple oatmeal shortcut.
Store leftover baked oatmeal in an airtight container in the refrigerator, where it will stay fresh for up to five days.
To reheat, warm individual portions in the microwave for about 30 seconds, or freeze baked squares for up to two months and thaw overnight in the fridge before reheating.

This one has earned a permanent spot in my breakfast rotation, and here’s why I think you’ll feel the same.

- It’s naturally customizable: Whether you want it dairy-free, higher in protein, or lower in sugar, the base recipe adapts easily.
- It tastes like a treat: The warm apple and maple flavor feels indulgent, even though it’s a genuinely healthy apple oatmeal bake for weight loss-friendly mornings.
FAQs
Can I use quick oats instead of rolled oats?
You can, but the texture will turn out softer and less chewy, so old-fashioned rolled oats are the better choice here.
Can I make this a healthy apple oatmeal bake with yogurt added?
Yes, stirring a spoonful of yogurt into your bowl right before eating adds creaminess and a boost of protein without changing the base recipe.
How do I know when it’s fully baked?
The top should look golden brown and the center should feel set rather than jiggly when you gently press it.
Can I prep this the night before like an overnight baked apple oatmeal?
Definitely, just keep your wet and dry ingredients separate in the fridge overnight, then combine and bake fresh the next morning.
Is this similar to the pioneer woman apple cinnamon baked oatmeal style?
It follows the same comforting, cinnamon-apple approach, just with my own simplified method and lightly sweetened maple flavor.
If you love this kind of cozy, oat-based breakfast, it’s worth trying a fruitier variation too, like this blueberry baked oatmeal for mornings when apples aren’t in season.
