Baked Apple Cinnamon Oatmeal Recipe Ingredients

For the Oatmeal Base

Rolled oats – Use old-fashioned oats for the perfect chewy texture that holds up well when baked.
Milk – Choose your favorite milk, dairy or plant-based, to add creaminess and keep the oatmeal moist.
Egg – Helps bind the ingredients together while adding a boost of protein to the Baked Apple Cinnamon Oatmeal Recipe.
Maple syrup – A natural sweetener that brings warmth and depth without overpowering the cinnamon.

For the Apple Cinnamon Layer

Apples – Peel and chop tart or sweet apples like Granny Smith or Fuji for tender, flavorful bursts in every bite.
Ground cinnamon – The key spice that lends that comforting, aromatic touch everyone loves in this dish.
Nutmeg (optional) – Adds a subtle warmth and complexity to balance the sweetness.

For Topping and Serving

Chopped nuts (walnuts or pecans) – Toasted for a crunchy contrast and extra nutrition.
Greek yogurt or cream – Dollop on top for creaminess and a tangy finish.
Honey or extra maple syrup – Drizzle over before serving for an indulgent touch.

How to Make Baked Apple Cinnamon Oatmeal Recipe

Preheat your oven to 350°F and lightly grease an 8×8-inch baking dish with butter or cooking spray. This ensures the oatmeal won’t stick and bakes evenly for a perfect crisp edge.
Combine Base in a large bowl by whisking rolled oats, milk, egg, maple syrup, and a pinch of salt until smooth and creamy.

For the Apple Cinnamon Layer:

Toss chopped apples with ground cinnamon and a pinch of nutmeg (if desired) in a medium bowl until each piece is coated in fragrant, warming spices.
Layer the dish by spreading half of the oatmeal base evenly, topping with the cinnamon-spiced apples, then pouring the remaining oat mixture over for a balanced bake.
Bake uncovered on the middle rack for 35–40 minutes, until the oatmeal is puffy, golden brown around the edges, and set in the center when gently shaken.
Rest the baked oatmeal for 5 minutes out of the oven; this cooling step helps it firm up nicely and deepens the cozy cinnamon-apple flavors.
Serve the oatmeal warm, garnished with toasted nuts for crunch, a dollop of Greek yogurt for creaminess, and a drizzle of honey or extra maple syrup.

Optional: Sprinkle extra cinnamon and toasted pecans for added crunch.

Don’t Overmix: Stir ingredients until just combined to keep the oatmeal tender, not dense or gummy.
Even Apple Coating: Toss apples well in cinnamon and nutmeg to ensure every bite bursts with warm spice flavor.

Baked Apple Cinnamon Oatmeal Recipe FAQs

How long can I store leftover Baked Apple Cinnamon Oatmeal in the fridge?
You can store leftovers in an airtight container in the refrigerator for up to 3 to 4 days. Be sure to reheat gently to preserve the moist, tender texture.
