Ingredients You’ll Need

The magic of this Apple Cinnamon Baked Oatmeal Recipe lies in its simple but essential ingredients. Each one plays a role in creating the perfect balance of texture, flavor, and color, turning everyday pantry staples into something truly delicious.

2 cups rolled oats: These provide a hearty, chewy base that holds everything together beautifully; avoid instant oats for the best texture.
1 teaspoon baking powder: Adds a slight lift so the oatmeal isn’t too dense.
1/2 teaspoon ground cinnamon: The star spice that brings warmth and depth to the dish.
1/4 teaspoon ground nutmeg: A subtle touch of nutmeg complements the cinnamon perfectly.
1/4 teaspoon salt: Enhances all the flavors and balances the sweetness.
2 cups milk: Use dairy or your favorite non-dairy alternative for creaminess.
1/4 cup maple syrup: Natural sweetness that blends beautifully with the apples and spices.
2 tablespoons melted butter: Adds richness and a slight buttery flavor; coconut oil works great for a dairy-free option.
1 large egg: Helps bind the ingredients while keeping the oatmeal moist.
1 teaspoon vanilla extract: Brings a lovely aromatic note that enhances the maple and cinnamon.
2 medium apples, peeled and diced: Fresh apples provide sweet juiciness and a delightful texture.
1/4 cup chopped walnuts or pecans (optional): Adds crunch and nutty flavor if you want a little extra texture.
2 tablespoons brown sugar (optional): Sprinkle on top for a caramelized, crunchy finish after baking.

How to Make Apple Cinnamon Baked Oatmeal Recipe

Step 1: Prepare Your Oven and Dish

Start by preheating your oven to 375 degrees Fahrenheit (190 degrees Celsius) and greasing an 8×8 inch baking dish. This step is essential to prevent the oatmeal from sticking and ensures even browning during baking.

Step 2: Mix the Dry Ingredients

In a large bowl, combine your rolled oats, baking powder, cinnamon, nutmeg, and salt. Give these a good whisk to make sure the spices and baking powder are evenly distributed, which helps the dish bake uniformly and taste balanced.

Step 3: Whisk the Wet Ingredients

In a separate bowl, whisk together the milk, maple syrup, melted butter (or coconut oil), the lightly beaten egg, and vanilla extract. This mixture brings moisture and sweetness to the dish, making it soft, flavorful, and slightly custardy once baked.

Step 4: Combine Wet and Dry

Pour the wet ingredients into the dry mixture and gently stir just until combined. Over-mixing can lead to a dense texture, so keep it light and airy to maintain a deliciously tender bite.

Step 5: Fold in Apples and Nuts

Carefully fold in the diced apples and nuts if you’re using them. This step adds bursts of juicy freshness and a lovely crunch throughout the oatmeal, elevating every spoonful into a texture-rich delight.

Step 6: Bake and Finish

Pour the mixture into your prepared baking dish, spreading it out evenly. If you want a sweet, crispy topping, sprinkle the brown sugar over the surface. Bake for 35 to 40 minutes or until the oatmeal is set and the top is lightly golden. You’ll know it’s done when a toothpick inserted in the center comes out clean.

Step 7: Let Cool Slightly

After baking, allow the oatmeal to cool for a few minutes. This resting time makes it easier to cut and serves to let the flavors deepen and meld together.

FAQs

Can I use quick oats instead of rolled oats?

While rolled oats give the best texture for this Apple Cinnamon Baked Oatmeal Recipe, you can use quick oats if that’s what you have. Just expect the baked oatmeal to be softer and less chewy.

Can I add other fruits or mix-ins?

Yes, this recipe is very versatile. Try adding dried cranberries, raisins, chopped pears, or even a handful of chocolate chips for a different twist. Just be mindful of moisture content to keep the texture right.

How can I make this recipe vegan?

To make the Apple Cinnamon Baked Oatmeal Recipe vegan, use a flax egg (1 tablespoon flaxseed meal + 3 tablespoons water, mixed and set aside) instead of a regular egg, and swap butter for coconut oil or a vegan butter substitute.
