🍌 What Is Banana Baked Oatmeal?
Banana Baked Oatmeal is a hearty, oven-baked breakfast dish that combines the creamy comfort of oatmeal with the flavor and texture of banana bread. Instead of standing over a stove stirring oats, you simply mix everything in one bowl, pour it into a dish, and let your oven do the work. The result? A warm, soft-baked casserole that’s slightly sweet, deeply satisfying, and totally customizable.
Unlike traditional stovetop oatmeal, banana baked oatmeal holds its shape, making it easy to slice or scoop. It’s packed with nutrient-dense ingredients like rolled oats, ripe bananas, and eggs, offering a solid mix of fiber, healthy fats, and protein to keep you energized all morning.
Whether you’re looking for a healthy breakfast for the kids, a make-ahead option for busy weekdays, or a cozy weekend treat, baked oatmeal with bananas delivers both taste and nutrition in one easy dish.
🥄 Ingredients You’ll Need for Banana Baked Oatmeal
Making Banana Baked Oatmeal only requires simple, wholesome ingredients — many of which you probably already have in your pantry. Here’s what you’ll need:
🌾 Main Ingredients
- Old-Fashioned Rolled Oats (3 cups)
The base of your baked oatmeal. These oats hold their shape and absorb moisture perfectly for a soft, yet sturdy texture. - Ripe Bananas (1 cup, mashed)
Use bananas that are spotty and very ripe — the sweeter, the better. They provide natural sweetness, moisture, and flavor. - Milk (1⅓ cups)
Choose dairy or a plant-based milk like almond, oat, or soy. It adds creaminess and binds the oats. - Eggs (2 large)
These help hold everything together and provide protein. For an egg-free version, substitute with ⅓ cup applesauce or more banana. - Pure Maple Syrup (⅓ cup)
Adds just the right amount of sweetness. You can also use honey or brown sugar. - Unsalted Butter (¼ cup, melted)
Brings richness and prevents the oatmeal from tasting rubbery. For a dairy-free option, use melted coconut oil. - Pure Vanilla Extract (1 tsp)
Enhances the banana flavor and gives the oatmeal that “banana bread” aroma.
🧂 Dry Ingredients
- Baking Powder (1 tsp)
Helps lift the oatmeal slightly and keeps it from being too dense. - Ground Cinnamon (1 tsp)
Adds warmth and spice — feel free to increase if you love cinnamon! - Salt (¼ tsp)
Balances the sweetness and brings out the other flavors.
🥜 Optional Add-Ins
- Chopped Walnuts (¾ cup)
Adds crunch and healthy fats. Pecans, almonds, or sunflower seeds also work. - Toppings:
Try a drizzle of peanut butter, sliced bananas, maple syrup, fresh berries, or even a sprinkle of chocolate chips for a treat.
👩🍳 How to Make Banana Baked Oatmeal (Step-by-Step)
One of the best things about Banana Baked Oatmeal is how quickly it comes together. With just one bowl, one pan, and a handful of ingredients, you’ll have a healthy, comforting breakfast that’s oven-ready in under 10 minutes.
🥣 Step 1: Preheat & Prep Your Pan
Set your oven to 350°F (177°C) and move the oven rack to the lower third position. Grease a 9×9-inch square or 11×7-inch rectangle pan with nonstick spray. (Avoid using an 8×8-inch — it’s too small.)
💡 Pro Tip: A white ceramic or glass casserole dish gives the best presentation and even baking.
🥄 Step 2: Mix the Wet Ingredients
In a large mixing bowl, whisk together:
- 1⅓ cups milk (dairy or non-dairy)
- 2 large eggs
- ⅓ cup pure maple syrup
- ¼ cup melted unsalted butter
- 1 cup mashed ripe bananas (about 2 large)
- 1 tsp pure vanilla extract
Mix until everything is fully combined.
🌾 Step 3: Add Dry Ingredients
Add to the same bowl:
- 3 cups old-fashioned rolled oats
- 1 tsp baking powder
- 1 tsp ground cinnamon
- ¼ tsp salt
Whisk everything together gently. If you’re using chopped walnuts, fold in ¾ cup now.
🥘 Step 4: Pour & Bake
Pour the batter into your prepared dish and smooth the top.
- Bake for 30–35 minutes until the edges are golden and the center appears almost set (for soft texture).
- Want a firmer texture? Bake an additional 5–10 minutes until fully set.
⏱️ Step 5: Cool & Serve
Let cool for 5 minutes before serving. You can spoon it into bowls or slice it into squares. Add your favorite toppings like banana slices, berries, peanut butter, or more maple syrup.
✅ Expert Tips for Perfect Banana Baked Oatmeal
Even though Banana Baked Oatmeal is super simple, a few smart tips can make the difference between good and unforgettable. Here’s how to get it just right every time:
🍌 1. Use Overripe Bananas
The riper the bananas, the sweeter and more flavorful your baked oatmeal will be. Look for bananas with brown spots — they mash easier and blend beautifully into the batter.
🥛 2. Choose the Right Oats
Stick with old-fashioned rolled oats for the perfect soft-and-chewy texture. Quick oats can make the bake too mushy, while steel-cut oats require pre-soaking and longer baking time.
⏳ 3. Don’t Let the Batter Sit
Once the ingredients are mixed, get it into the oven ASAP. Letting the batter rest too long allows the oats to soak up all the liquid, leading to a dense, gummy texture.
🧁 4. Want Portable Portions? Use a Muffin Tin
For on-the-go breakfasts or lunchbox snacks, divide the batter into a greased 12-count muffin tin. Bake for 28–30 minutes. No liners needed — just spray the pan well!
🥥 5. Going Dairy-Free or Egg-Free?
- Replace butter with melted coconut oil
- Swap eggs for ⅓ cup applesauce or extra mashed banana
These substitutions keep the recipe moist and flavorful without sacrificing structure.
🌡️ 6. Test for Doneness
For a soft, spoonable texture, bake just until the center is almost set. For firmer, sliceable squares, bake 5–10 minutes longer until fully set in the center.
🔄 Flavor Variations & Dietary Swaps
One of the best things about Banana Baked Oatmeal is how endlessly customizable it is. Whether you want to switch things up for the season or accommodate dietary needs, these variations will keep breakfast exciting and inclusive.
🍫 1. Chocolate Chip Banana Baked Oatmeal
Add ½ to ¾ cup of chocolate chips (dark, milk, or mini) to the batter before baking. You’ll get gooey chocolate pockets in every bite — perfect for kids or a brunch treat.
🫐 2. Blueberry Banana Oatmeal Bake
Gently fold in ¾ cup of fresh or frozen blueberries for a fruity twist. For even more flavor, sprinkle cinnamon-sugar on top before baking.
🌰 3. Nut-Free Version
Skip the walnuts and use sunflower seeds or pumpkin seeds for added texture. Or leave them out completely for a smoother bite — still delicious and school-lunch safe.
🌱 4. Vegan Banana Baked Oatmeal
- Replace eggs with applesauce or flax eggs (1 tbsp ground flax + 3 tbsp water = 1 egg)
- Use plant-based milk and coconut oil instead of dairy
🥥 5. Tropical Twist
Swap cinnamon for cardamom and stir in shredded coconut and diced pineapple. Top with toasted coconut flakes for a vacation-in-a-bowl vibe.
🍯 6. Sweetness Adjustments
Prefer less sugar? Use only 2 tablespoons of maple syrup or none at all if your bananas are super ripe. Want more? Drizzle extra syrup after baking for a sweeter touch.
💡 Pro Tip: Keep add-ins under 1 cup total to maintain the right texture and bake time.
🧊 Storage, Reheating, and Freezing Tips
One of the top perks of Banana Baked Oatmeal is its incredible shelf life. Whether you’re meal prepping for the week or freezing leftovers for later, this dish holds up beautifully.
🧺 How to Store
After baking, let your banana baked oatmeal cool completely. Then:
- Cover tightly with plastic wrap or foil
- Or transfer to an airtight container
- Refrigerate for up to 1 week
Slicing it into single servings makes grab-and-go breakfasts easy and mess-free.
🔥 How to Reheat
- Microwave: Place one slice or scoop in a bowl and microwave for 30–60 seconds
- Oven: Cover with foil and bake at 350°F (177°C) for about 10 minutes to rewarm multiple servings at once
💡 Tip: Add a splash of milk before reheating to refresh the texture and keep it moist.
❄️ Can You Freeze Banana Baked Oatmeal? Absolutely.
This recipe freezes incredibly well. Just follow these steps:
- Let it cool completely
- Slice into individual portions
- Wrap each in plastic wrap or parchment
- Store in a freezer-safe bag or container for up to 3 months
To thaw:
- Defrost in the fridge overnight
- Or microwave a frozen portion for 1–2 minutes until heated through
This makes it perfect for batch-cooking breakfast for a month in advance.

❓ Frequently Asked Questions About Banana Baked Oatmeal

Yes! Replace the eggs with ⅓ cup of unsweetened applesauce or extra mashed banana. For a vegan option, flax eggs work well too.
