How to Make Apple Cinnamon Baked Oatmeal Recipe
Step 1: Prepare Your Oven and Baking Dish
Start by heating your oven to 375°F (190°C) and greasing an 8×8 inch baking dish. This simple step ensures your baked oatmeal doesn’t stick and browns evenly, setting the stage for a flawless bake.
Step 2: Mix Dry Ingredients
In a large bowl, whisk together the rolled oats, baking powder, cinnamon, nutmeg, and salt. This blend of dry ingredients ensures each spoonful is perfectly spiced and balanced with the right texture and lift from the baking powder.
Step 3: Combine Wet Ingredients
In a separate bowl, mix the milk, maple syrup, melted butter (or coconut oil), beaten egg, and vanilla extract. Whisking these wet ingredients thoroughly creates a smooth, flavorful liquid that will soak the oats and carry their flavors beautifully.
Step 4: Bring Dry and Wet Together
Pour the wet mixture into the bowl of dry ingredients, stirring gently just until everything is combined. Avoid over-mixing to keep your final oatmeal tender—this ensures a moist yet structured dish.
Step 5: Fold in the Apples and Nuts
Gently fold diced apples and optional nuts into the batter. The apples add juicy bursts of sweetness and a tender texture, while nuts contribute a satisfying crunchy contrast that’s absolutely delightful.
Step 6: Transfer and Top
Pour the oatmeal batter evenly into your prepared baking dish and smooth the top. If you like a lightly sweet, caramelized crust, sprinkle the optional brown sugar over the surface now—this little touch creates magic when baked.
Step 7: Bake to Golden Perfection
Bake for about 35 to 40 minutes until the oatmeal is fully set and the top turns a light golden brown. A toothpick inserted in the center should come out clean, confirming it’s perfectly cooked through—warm, fragrant, and ready to enjoy.
Step 8: Cool Slightly and Serve
Let cool for a few minutes before serving to allow the oatmeal to set further and for easier portioning. This short wait rewards you with perfectly textured squares of comforting apple cinnamon goodness.
How to Serve Apple Cinnamon Baked Oatmeal Recipe

Garnishes
Fresh garnishes can elevate this baked oatmeal from great to unforgettable. Try a dollop of Greek yogurt or a splash of vanilla cream to add creamy tanginess, or sprinkle some chopped nuts or a dusting of cinnamon for extra aroma and crunch. A drizzle of warm maple syrup or honey is always a welcome finishing touch.
Side Dishes
Keep breakfast balanced and delicious by pairing this Apple Cinnamon Baked Oatmeal Recipe with fresh fruit like sliced bananas, berries, or oranges. A side of crispy bacon or a soft scrambled egg adds protein and contrast, turning this cozy dish into a complete morning feast.
Creative Ways to Present
For a brunch, consider cutting the baked oatmeal into squares and serving them on a platter with assorted toppings on the side—nuts, whipped cream, fruit compote—so guests can customize their bowls. You can also turn leftovers into individual jars layered with yogurt and fruit for a grab-and-go breakfast that feels gourmet.
Make Ahead and Storage
Storing Leftovers
Once cooled, store leftovers in an airtight container in the refrigerator for up to 4 days. This Apple Cinnamon Baked Oatmeal Recipe holds its flavor and texture beautifully, making it perfect for enjoying quick breakfasts throughout the week.
Freezing
If you want to enjoy this comforting dish anytime, slice the baked oatmeal into portions and freeze them individually. Wrap each piece tightly in plastic wrap and place in a freezer bag. Frozen oatmeal squares keep well for up to 3 months and thaw quickly when you need a fast nutritious meal.
Reheating
Reheat refrigerated or thawed portions in the microwave for about 1 to 2 minutes or in a warm oven until heated through. Adding a splash of milk or a pat of butter before reheating restores moisture and brings back that freshly baked taste we all crave.
FAQs
Can I use instant oats instead of rolled oats?
While instant oats cook faster, they tend to create a mushier texture in baked oatmeal. Rolled oats provide the perfect balance of chewiness and structure in this Apple Cinnamon Baked Oatmeal Recipe.
Do I have to peel the apples?
Peeling is optional but recommended if you prefer a smoother texture. Leaving the skin on adds extra fiber and a bit of color but can slightly change the mouthfeel.
Can this recipe be made vegan?
Absolutely! Use a plant-based milk like almond or oat milk, replace butter with coconut oil, and omit the egg or use a flax egg to keep it vegan-friendly without losing flavor or texture.
How do I make it less sweet?
You can reduce the maple syrup or omit the brown sugar topping for a less sweet version. The natural sweetness of the apples still shines through, so you won’t miss the added sugar.
Can I add other fruits or spices?
Definitely! Pears, berries, or dried fruits all mix wonderfully. You might also enjoy adding a pinch of cardamom or ginger for more spice variation—feel free to personalize this Apple Cinnamon Baked Oatmeal Recipe!
