Ingredients You’ll Need

These ingredients come together in a simple yet flavorful way, each playing an essential role. From the hearty rolled oats to the warm spices and naturally sweet apples, every element contributes to the dish’s inviting texture, sweetness, and color.

  • Old-fashioned rolled oats: Provides a chewy, hearty base that soaks up moisture beautifully while maintaining texture.
  • Ground cinnamon: Brings a warm, fragrant spiciness that complements the sweet apples perfectly.
  • Baking powder: Helps the oatmeal puff up slightly for a light, tender crumb.
  • Salt: Balances the sweetness and enhances all the flavors.
  • Large eggs: Bind all the ingredients together, giving the baked oatmeal structure.
  • Milk or milk alternative: Adds moisture and creaminess—choose your favorite dairy or plant-based milk.
  • Maple syrup or honey: Provides natural sweetness and depth of flavor.
  • Vanilla extract: Adds a subtle, sweet aroma that blends beautifully with cinnamon and apples.
  • Fresh apples: Peeled, cored, and diced for tender, fruity bursts in every bite.

How to Make Apple Cinnamon Baked Oatmeal Recipe

Step 1: Prepare the Apples

Start by peeling, coring, and dicing your apples into small chunks. This size ensures they soften perfectly during baking while still providing a lovely texture that complements the creamy oats. Using fresh apples brings a natural sweetness and moisture that is essential for this dish.

Step 2: Mix Dry Ingredients

In a large bowl, whisk together the rolled oats, ground cinnamon, baking powder, and a pinch of salt. This step evenly distributes the spices and leavening agent, which is key to a perfectly balanced flavor and texture throughout the baked oatmeal.

Step 3: Combine Wet Ingredients

In a separate bowl, whisk the eggs, milk, maple syrup (or honey), and vanilla extract together until smooth and well combined. This mixture adds moisture, sweetness, and that irresistible vanilla scent that will fill your kitchen as you bake.

Step 4: Bring It All Together

Pour the wet ingredients into the bowl with the dry oat mixture, then fold in the chopped apples gently. Mixing just until combined ensures the oats soak up the liquid without becoming mushy, while the apples stay nicely distributed.

Step 5: Transfer and Bake

Grease a baking dish, then pour in the oatmeal batter, spreading it evenly with a spatula. Bake in a preheated oven at 350°F (175°C) for 35 to 40 minutes. You’ll know it’s ready when the top turns a beautiful golden color and a toothpick inserted in the center comes out clean. The aroma at this point is downright irresistible!

Step 6: Cool and Serve

Let the baked oatmeal cool slightly before slicing. This resting time helps it set up perfectly so you get neat, satisfying squares that hold their shape whether you’re serving up a quick breakfast or a cozy brunch spread.

Garnishes

Top your baked oatmeal with a dollop of Greek yogurt or a splash of warm milk for creaminess. Sprinkle some chopped nuts or extra cinnamon on top to add crunch and enhance the flavors. A drizzle of maple syrup or honey at serving time can take it from good to irresistible.

Side Dishes

Pair this oatmeal with fresh fruit to brighten your plate and add refreshing contrast. Crispy bacon or sausage links offer a savory balance, while a warm cup of coffee or spiced chai rounds out the meal with comforting warmth.

Creative Ways to Present

For a fun twist, serve the Apple Cinnamon Baked Oatmeal in individual ramekins or mason jars — perfect for portion control and easy gifting. Layer it with yogurt and granola to create a breakfast parfait with extra texture and flavor that feels special.

Make Ahead and Storage

Storing Leftovers

Store any leftover Apple Cinnamon Baked Oatmeal in an airtight container in the refrigerator. It will keep fresh for up to 4 days, making it a convenient option for busy mornings or quick snacks during the week.

Freezing

This recipe freezes beautifully! Slice the baked oatmeal into portions and wrap each piece tightly in plastic wrap or foil before placing in a freezer-safe bag. Frozen portions can be kept for up to 3 months and thawed overnight in the fridge when ready to enjoy.

Reheating

To warm leftovers, microwave a slice for 30 to 60 seconds or reheat in the oven at 300°F (150°C) until hot throughout. Add a splash of milk or a spoonful of yogurt to refresh the texture and keep every bite creamy and delicious.

FAQs

Can I use other fruits instead of apples?

Absolutely! Pears, peaches, or berries make fantastic substitutions that give this baked oatmeal a new seasonal twist while maintaining the moist texture and natural sweetness.

Is this recipe gluten-free?

Yes, if you use certified gluten-free oats. Oats themselves are naturally gluten-free but can be cross-contaminated, so check your packaging if gluten sensitivity is a concern.

Can I make this recipe vegan?

Yes! Swap the eggs for flax eggs or a commercial egg replacer, and use a plant-based milk like almond or soy milk. Maple syrup is already vegan, so that part stays the same.

How sweet is the Apple Cinnamon Baked Oatmeal Recipe?

The sweetness is subtle and natural, balanced by the maple syrup (or honey) and fresh fruit, making it perfect for those who prefer a lightly sweetened breakfast without overpowering sugar.

Can I add nuts or seeds to the recipe?

Definitely! Chopped walnuts, pecans, or chia seeds can add delightful crunch and an extra boost of nutrition when stirred into the batter before baking.
