This Coffee Cake Baked Oatmeal Recipe relies on simple, everyday ingredients that work together beautifully to create a deliciously textured and flavorful dish. Each component is chosen to enhance the taste, moisture, and crumbly topping that makes this baked oatmeal so special.

Old-fashioned rolled oats (2 ½ cups): The hearty base provides a chewy, satisfying texture and fantastic fiber.
Cinnamon (1 teaspoon + 1 teaspoon): Adds warm, fragrant spice to both the oatmeal and the crumbly topping.
Baking powder (1 teaspoon): Gives the oatmeal just enough lift and fluffiness.
Sea salt (½ teaspoon): Enhances all the sweet and savory flavors, balancing the dish perfectly.
Milk, unsweetened almond milk preferred (2 cups): Keeps things creamy while keeping it light and dairy-free.
Maple syrup (2 tablespoons): Natural sweetness that complements the banana and cinnamon notes.
Ground flaxseed (1 tablespoon): Adds subtle nuttiness and a nutritional boost with omega-3s.
Coconut oil (1 tablespoon solidified + 3 tablespoons for topping): Brings a rich, tropical flavor and tender crumb.
Vanilla extract (1 teaspoon): Gives that irresistible aromatic depth to the entire dish.
Ripe bananas, mashed (½ cup): Natural sweetness and moisture that helps keep the oatmeal moist and flavorful.
Coconut butter (for drizzling): An optional luscious finish that melts beautifully on warm servings.
Coconut sugar (¼ cup): Sweetens the crumbly topping with a subtle caramel note.
Oat flour (½ cup): Works with the sugar and coconut oil to create the classic coffee cake crumble.

How to Make Coffee Cake Baked Oatmeal Recipe

Step 1: Preheat and Prepare Your Dish

First things first, set your oven to 375°F. This temperature ensures the oatmeal cooks evenly without drying out. Grease an 8×8-inch baking dish with cooking spray or a light coating of coconut oil—this keeps the oatmeal from sticking and makes for easy serving.

Step 2: Make the Topping

In a small bowl, combine the coconut sugar, oat flour, cinnamon, and coconut oil. Use a fork to mix everything until crumbly and well blended. The contrast of this sweet, crumbly topping against the soft baked oats is what makes this Coffee Cake Baked Oatmeal Recipe truly sing.

Step 3: Mix the Oatmeal Base

In a large bowl, stir together the rolled oats, cinnamon, baking powder, sea salt, almond milk, maple syrup, flaxseed, the solidified coconut oil, vanilla extract, and mashed bananas. Make sure everything is evenly incorporated so every spoonful has a perfect balance of flavors.

Step 4: Assemble and Bake

Pour the oatmeal mixture into your prepared baking dish, spreading it out evenly. Sprinkle the crumbly topping over the oatmeal, making sure it’s nice and even. Bake for 35 to 40 minutes, or until the topping is lightly browned and a toothpick inserted in the middle comes out clean.

Step 5: Cool and Serve

Allow the oven-baked oatmeal to cool for 10 to 15 minutes—this step helps it set up so it holds together when sliced. Cut into six generous portions, drizzle with coconut butter if you like, and enjoy warm. Trust me, there is nothing quite like the aroma and comfort of this Coffee Cake Baked Oatmeal Recipe fresh from the oven.

Garnishes

A little extra flair goes a long way. Try a light drizzle of coconut butter or a dollop of Greek yogurt on top to add creaminess and a cooling counterpoint to the warm oats. Fresh berries or a sprinkle of chopped nuts bring a pop of color and crunch, making each bite even more delightful.

Side Dishes

This baked oatmeal pairs wonderfully with fresh fruit salad or a simple green smoothie for a balanced breakfast that’s both energizing and wholesome. If you’re serving it for brunch, a side of crispy bacon or turkey sausage adds a savory contrast that your taste buds will appreciate.

Creative Ways to Present

Want to impress guests or turn breakfast into a special occasion? Serve individual portions in small ramekins or mason jars topped with extra crumble and edible flowers or fresh mint leaves. Layer the baked oatmeal with yogurt and fruit in parfait glasses for a stunning presentation that tastes as good as it looks.

Make Ahead and Storage

Storing Leftovers

Store any leftover Coffee Cake Baked Oatmeal Recipe in an airtight container in the refrigerator for up to 4 days. This makes for a fantastic grab-and-go breakfast or snack—the flavors even deepen after a day or two!

Freezing

You can freeze individual portions wrapped tightly in plastic wrap or foil, then placed in a freezer-safe bag for up to 3 months. Thaw overnight in the fridge before reheating, and you’ll have breakfast ready in no time.

Reheating

Warm leftovers in the microwave for about 1 to 2 minutes or pop them in a preheated oven at 350°F for 10-15 minutes until heated through. Add a little more coconut butter or an extra splash of almond milk if it feels dry.

FAQs

Can I use a different type of milk in this recipe?

Absolutely! While almond milk is my favorite for its subtle flavor and creaminess, any plant-based or dairy milk will work fine. Just be sure it’s unsweetened to control sweetness.

Is it possible to make this recipe gluten-free?

Yes! Just ensure your oats and oat flour are certified gluten-free, as some oats can be cross-contaminated during processing.

Can I substitute the mashed bananas with something else?

Definitely. Unsweetened applesauce or pumpkin puree are excellent options that keep the moisture and add their own unique flavors to the Coffee Cake Baked Oatmeal Recipe.

How sweet is this baked oatmeal?

It’s mildly sweet with natural sugars from bananas and maple syrup paired with the coconut sugar topping. If you prefer it sweeter, feel free to add a bit more maple syrup into the batter or extra topping sugar.

Can I double the recipe for a larger batch?

Yes, doubling is easy! Just use a larger baking dish and increase the baking time slightly, checking until the center is set and the topping is golden.

This Coffee Cake Baked Oatmeal Recipe is honestly one of my go-to morning treats because it combines convenience, nutrition, and irresistible flavor all in one dish.
