Ingredients You’ll Need

• 2 ½ medium honeycrisp apples (about 2 cups), peeled, cored, and diced: These sweet, juicy apples add wonderful flavor and moisture. Feel free to substitute with Granny Smith or Fuji apples for a different twist.
• 1 ½ teaspoons ground cinnamon, divided: This spice brings warmth to the dish. Use fresh ground cinnamon for a more intense flavor.
• ½ cup (160 g) real maple syrup, divided: Pure maple syrup not only sweetens but also adds a rich, complex flavor. If you need an alternative, agave syrup can work well.
• 2 ⅓ cups (206 g) rolled oats: Old-fashioned rolled oats are best for texture. Quick oats might lead to a mushier consistency, so stick with rolled oats if possible.
• 1 teaspoon baking powder: This ingredient helps the oatmeal rise and gives it a fluffy texture.
• ¾ teaspoon kosher salt: Balances sweetness and enhances overall flavor.
• ¼ teaspoon ground nutmeg: This adds a cozy warmth and pairs beautifully with cinnamon.
• 2 large eggs, room temperature: They help bind the mixture and give it structure.
• 2 cups (488 g) whole milk: Adds creaminess to the baked oatmeal. You can substitute with almond milk or oat milk for a dairy-free option.
• ¼ cup (½ stick / 57 g) unsalted butter, melted: This provides a rich flavor and moist texture.
• 1 teaspoon vanilla extract: Enhances all the other flavors, making the dish even more delightful.
• ¾ cup (88 g) walnuts, chopped: They add crunch and healthy fats. If you have nut allergies, you can skip them or substitute with sunflower seeds.

How to Make Apple Cinnamon Baked Oatmeal

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C). It helps ensure even cooking for the oatmeal.
2. Prepare the Apples: In a small bowl, toss the diced honeycrisp apples with ½ teaspoon of cinnamon and 1 teaspoon of maple syrup until they’re well-coated. Set aside.
3. Reserve Topping Apples: Measure out about ½ cup of these coated apples and reserve them for topping later. Set the remaining apples aside to mix into the batter.
4. Mix Dry Ingredients: In a medium bowl, whisk together 2 ⅓ cups of rolled oats, 1 teaspoon of baking powder, ¾ teaspoon of kosher salt, the remaining cinnamon (1 teaspoon), and ¼ teaspoon of ground nutmeg.
5. Combine Wet Ingredients: In a large bowl, whisk the 2 large eggs until well combined. Add in 2 cups of whole milk, ¼ cup of melted unsalted butter, and the remaining ½ cup of maple syrup along with 1 teaspoon of vanilla extract. Whisk until the mixture is smooth.
6. Incorporate Oat Mixture: Gradually add the oat mixture to the wet ingredients, stirring until everything is well combined. Then, fold in the chopped walnuts and the reserved apples (excluding those set aside for topping).
7. Transfer to Baking Dish: Pour the entire mixture into a prepared 9×9-inch baking dish, spreading it into an even layer. Scatter the reserved apples evenly over the top.
8. Bake: Place the dish in the preheated oven and bake for 45 to 50 minutes. The edges should be golden brown, and a toothpick inserted in the center should come out clean.
9. Cool Down: Allow the oatmeal to cool for 5 to 10 minutes before serving. This helps it set up a bit more, ensuring nice, clean squares when you cut it.

Storing & Reheating

Store any leftovers in an airtight container in the refrigerator for up to a week. If you find yourself with more than you can eat, this baked oatmeal freezes beautifully! Just cut it into squares, wrap them tightly in plastic wrap, and place them in a freezer-safe container or bag. It can last up to 3 months in the freezer. To reheat, simply pop it in the microwave for about 30-60 seconds, or until warmed through. Be aware that freezing may slightly change the texture, but a splash of milk before reheating can help refresh it!

Chef’s Helpful Tips

• Always use room temperature eggs and milk for a smoother batter and better incorporation.
• If you prefer a softer, creamier texture, slightly underbake the oatmeal; a toothpick should show a few moist crumbs.
• Feel free to mix in other fruits like berries or sliced bananas for variety.
• If you’re not a fan of nuts, consider adding dried fruit instead for a chewy texture.
• This recipe is great for meal prep; you can make it in advance and enjoy it throughout the week!

There’s something about Apple Cinnamon Baked Oatmeal that feels special, yet it’s so wonderfully simple. It’s packed with flavors that sweep you away to a cozy autumn morning, no matter the season. I encourage you to make a batch, serve it warm with a drizzle of extra maple syrup, and maybe even a dollop of yogurt on the side. Enjoy every bite!

Recipe FAQs

Can I use quick oats instead of rolled oats?

Using quick oats can change the texture of your baked oatmeal, making it more mushy rather than hearty and chewy. Stick to rolled oats for the best results; they hold their shape and create a nice texture.

Can I prepare this recipe ahead of time?

Absolutely! You can prepare the batter the night before and store it in the refrigerator. Just pour it into the baking dish in the morning, add your apple topping, and bake it fresh for breakfast.

What can I substitute for milk to make it dairy-free?

Almond milk or oat milk works wonderfully as a dairy-free substitute. Just keep in mind that different milk varieties can affect the overall creaminess a bit.

Can I add other fruits or toppings?

Yes! Feel free to mix in other fruits like blueberries or sliced bananas, or top it with a dollop of Greek yogurt or a sprinkle of granola for some extra crunch. The possibilities are endless!
