Ingredients You’ll Need

Rolled oats: Old-fashioned rolled oats work best because they hold their texture after baking.

Apples: Use firm apples such as Honeycrisp, Gala, Fuji, or Granny Smith. Dice them small so they soften nicely.

Milk: Dairy milk or plant-based milk both work.

Egg: Helps the baked oatmeal set. If needed, you can use a flax egg.

Maple syrup or honey: Adds gentle sweetness.

Cinnamon: Gives the oatmeal its cozy apple-pie style flavor.

Vanilla extract: Adds warmth and makes the oatmeal taste more complete.

Baking powder: Helps the baked oatmeal feel a little lighter.

Salt: A small pinch balances the sweetness.

Optional add-ins: Chopped walnuts, pecans, raisins, dried cranberries, or a few chocolate chips if breakfast needs a little encouragement.

How to Make Apple Cinnamon Baked Oatmeal

Preheat the oven and lightly grease a baking dish.

In a mixing bowl, stir together the oats, cinnamon, baking powder, and salt.

In another bowl, whisk the milk, egg, maple syrup or honey, and vanilla.

Add the wet ingredients to the dry ingredients and stir until combined.

Fold in the diced apples and any optional nuts or dried fruit.

Pour the mixture into the prepared baking dish and spread it evenly.

Bake until the oatmeal is set, lightly golden on top, and the apples are tender.

Let it cool for a few minutes before slicing. It will smell very convincing, but giving it a moment helps it hold together.

Serve warm with yogurt, milk, peanut butter, extra apple slices, or a drizzle of maple syrup.

Tips for Success

Use rolled oats, not steel-cut oats. Steel-cut oats need more liquid and a longer cooking time.

Dice the apples small so they soften during baking.

Let the baked oatmeal rest before slicing.

Add a splash of milk when reheating if you like a softer texture.

Do not overbake it. The center should be set but still moist.

Easy Variations

Add chopped walnuts or pecans for crunch.

Add raisins or dried cranberries for extra sweetness.

Use pears instead of apples.

Add a spoonful of peanut butter or almond butter to the batter.

Use plant-based milk and a flax egg for a dairy-free version.

Add a little nutmeg for more warm spice flavor.

What to Serve With It

Apple cinnamon baked oatmeal is great with Greek yogurt, fresh fruit, coffee, tea, scrambled eggs, or a smoothie.

For a quick breakfast, warm a slice and add a spoonful of yogurt on top. It feels like effort, but really the oven did the responsible part yesterday.

How to Store Baked Oatmeal

Store leftovers in an airtight container in the refrigerator for up to 4 days.

Reheat individual slices in the microwave until warm.

You can also freeze baked oatmeal slices for up to 2 months. Wrap them individually, then thaw overnight in the refrigerator or reheat from frozen.

If the oatmeal feels dry after reheating, add a splash of milk.
