How to Make Apple Cinnamon Baked Oatmeal
Making this dish is straightforward and stress-free. You start by mixing your dry ingredients in one bowl and your wet ingredients in another. Once you combine them, you fold in your fresh apple pieces. Pour the mixture into a greased baking dish and pop it into the oven. The magic happens as the oats soak up the liquid and the apples soften into sweet, tender nuggets. In about 35 to 40 minutes, you will have a beautiful, steaming dish of breakfast goodness ready to be sliced and served.
Ingredients
- 2 cups old-fashioned rolled oats (do not use instant oats)
- 1 teaspoon baking powder
- 1 teaspoon ground cinnamon
- 1/2 teaspoon ground ginger
- 1/2 teaspoon salt
- 2 cups milk (dairy or unsweetened almond/oat milk)
- 1 large egg, room temperature
- 1/4 cup pure maple syrup or honey
- 2 tablespoons melted butter or coconut oil
- 1 teaspoon pure vanilla extract
- 2 medium apples (like Honeycrisp or Granny Smith), peeled and chopped into small cubes
- 1/2 cup chopped walnuts or pecans (optional for crunch)
Directions
- Preheat your oven to 375°F (190°C). Lightly grease an 8×8-inch or 9×9-inch baking dish with butter or non-stick spray.
- In a large mixing bowl, whisk together the rolled oats, baking powder, cinnamon, ginger, and salt until well combined.
- In a medium bowl, whisk the milk, egg, maple syrup, melted butter (or oil), and vanilla extract until smooth.
- Pour the wet ingredients into the dry ingredients and stir with a spatula until just combined.
- Gently fold in the chopped apples and the nuts if you are using them.
- Pour the mixture into the prepared baking dish. Spread it out evenly with your spatula.
- Bake for 35 to 40 minutes, or until the top is golden brown and the center is set (it shouldn’t jiggle too much when you shake the pan).
- Remove from the oven and let it cool for 5 to 10 minutes before slicing. This helps the oatmeal set so it doesn’t fall apart.

How to Serve Apple Cinnamon Baked Oatmeal
This oatmeal is delicious on its own, but you can elevate it with a few simple toppings. Serve a warm slice in a bowl with a splash of cold milk or a dollop of Greek yogurt for extra protein. If you like it sweeter, drizzle a little extra maple syrup or honey over the top. For a bit of luxury, add a spoonful of almond butter or peanut butter. If you are serving this for a weekend brunch, a side of fresh berries or a few slices of turkey sausage makes it a complete and beautiful meal.
How to Store Apple Cinnamon Baked Oatmeal
Storing this dish is very easy. Once the oatmeal has cooled completely, cover the baking dish tightly with plastic wrap or foil. You can also transfer individual slices to airtight containers. It stays fresh in the refrigerator for up to 5 days. If you want to keep it longer, you can freeze it! Wrap individual portions in plastic wrap and place them in a freezer bag. They will last for up to 3 months. To reheat, simply microwave a slice for 45-60 seconds or warm it in the oven at 350°F until heated through.
Expert Tips for Perfect Apple Cinnamon Baked Oatmeal
- Use Rolled Oats: Avoid using “quick” or “instant” oats. They will turn mushy in the oven. Old-fashioned rolled oats provide the best chewy texture.
- Apple Choice: Use firm apples that hold their shape when baked. Granny Smith adds a nice tartness, while Honeycrisp or Fuji offer a lovely sweetness.
- Don’t Overbake: Check the oatmeal at the 35-minute mark. You want it to be firm but still moist. Overbaking can make it dry.
- Toast the Nuts: If you are adding walnuts or pecans, toast them in a dry pan for 2 minutes before adding them to the batter. This brings out a much deeper flavor.
- Let it Rest: Resist the urge to cut it immediately! Letting it sit for a few minutes allows the oats to finish absorbing any remaining liquid.
Delicious Variations
- Berry Blast: Swap one of the apples for a cup of fresh blueberries or raspberries for a tart, colorful twist.
- Pumpkin Spice: Replace half of the milk with pumpkin puree and use pumpkin pie spice instead of just cinnamon.
- Chocolate Chip: Stir in 1/4 cup of dark chocolate chips for a treat that feels like a real indulgence.
- Vegan Option: Use a flax egg (1 tbsp ground flaxseed mixed with 3 tbsp water) instead of the chicken egg and use coconut oil and plant-based milk.
- Pear and Cardamom: Use chopped pears instead of apples and add a pinch of ground cardamom for an elegant, floral flavor profile.
Frequently Asked Questions
1. Can I make this ahead of time?
Yes! You can assemble the wet and dry ingredients separately the night before. However, don’t mix them until you are ready to bake, or the oats will soak up all the liquid and become too soft before they hit the oven.
2. Can I use steel-cut oats?
No, steel-cut oats require much more liquid and a longer cooking time. This specific recipe is designed for rolled oats.
3. Is this recipe gluten-free?
Oats are naturally gluten-free, but they are often processed in facilities with wheat. To make this 100% gluten-free, ensure your oats are certified gluten-free.
4. Can I omit the sugar?
The maple syrup provides moisture and sweetness. If you omit it, you might want to add a bit more milk or applesauce to keep the texture right. The apples will provide some natural sweetness.

5. Do I have to peel the apples?
That is up to you! Leaving the skin on adds extra fiber and a bit of color, but some people prefer the softer texture of peeled apples.
6. Why is my baked oatmeal soggy?
This usually happens if you didn’t bake it long enough or if your measurements were off. Make sure to use the exact amount of milk listed.
7. Can I bake this in a muffin tin?
Yes! These make great “oatmeal cups.” Just grease the muffin tin well and reduce the baking time to about 20-25 minutes.
8. What can I use instead of eggs?
A “flax egg” or 1/4 cup of unsweetened applesauce works well as a binder in this recipe.
9. Is it okay to use frozen apples?
Frozen apples release a lot of water as they thaw, which might make the oatmeal soggy. It is best to use fresh apples for the best texture.
10. How do I make the top crunchy?
Sprinkle a tablespoon of brown sugar or some extra oats and nuts on top right before you put it in the oven.
