When it comes to wholesome breakfast recipes, oatmeal ranks high on my list of favorites. And when your wholesome breakfast tastes like a combination of banana bread, banana cake, and banana pudding, what is better than that?!
Made with fiber-rich oats, calcium-rich milk, and potassium-rich bananas, not only is this recipe for Banana Baked Oatmeal incredibly rich and and sweet, it is packed with nutrient-dense ingredients that will keep you going strong for hours!
Made with Simple Ingredients
Banana Baked Oatmeal recipe uses ingredients you probably always have on hand, like oats, milk, and eggs. And this recipe saves those overripe bananas from being thrown away!
- Oats: Old-fashioned rolled oats or quick-cooking oats can both be used when making baked oatmeal. Do not use steel-cut oats.
- Milk: Any variety of milk or non-dairy milk, such as almond milk or soy milk, works perfectly in this baked oatmeal recipe.
- Ripe Bananas: The riper your bananas, the sweeter this oatmeal will be.
- Maple Syrup: Just a little bit of pure maple syrup helps to sweeten the oatmeal. If you don't happen to have maple syrup on hand, honey will work as well.
- Egg: The egg will give this baked oatmeal a more bread budding or cake-like consistency. Think banana cake in oatmeal form. YUM!
- Butter/Coconut Oil: A tad bit of either melted coconut oil or melted butter is added to give this baked oatmeal richness.
- Baking Powder: Baking powder is a bit of a surprise in oatmeal, but it helps the oatmeal to rise slightly and form a thick, custard-like consistency.
5 Minute Prep
Baked Banana Oatmeal only takes 5 minutes of prep and can be made in advance, making it a great option for busy weekdays and lazy weekends. It is as easy as mash, whisk, and bake. Super simple, and perfect every time.
Serve Warm or Chilled
Banana Baked Oatmeal can be served warm from the oven, at room temperature, or even chilled. It is delicious served plain or with sliced bananas, chopped walnuts, additional maple syrup, and/or a drizzle of nut butter.
Recipe Modifications
- Egg-Free Modification: Simply omit the egg, keeping in mind that the baked oatmeal won't set up quite as much, but will still be delicious.
- Dairy-Free Modification: Use your favorite non-dairy milk, like almond milk, coconut milk, or soy milk and opt to use coconut oil instead of butter.
- Sweeter Oatmeal: Increase the amount of sweetener added by up to an additional ¼ cup if you like really sweet oatmeal.
- Oil-Free Baked Oatmeal: Use nut butter (any variety) in place of the coconut oil.
- Banana Chocolate Chip Oatmeal: Add ⅓ to ½ cup chocolate chips to the oatmeal batter before baking for a decadent treat.
- Peanut Butter Banana Oatmeal: Replace the oil with creamy peanut butter.
Make-Ahead & Storage Instructions
- Assemble Up to 24 Hours In Advance: Combine all the ingredients together and pour the mixture into a greased baking sheet. Cover tightly and refrigerate for up to 24 hours. When ready to bake, remove the dish from the fridge, uncover, and let it sit at room temperature while the oven preheats to 350 degrees F. Bake for 40-45 minutes, or until set.
- Meal-Prep for the Week: Assemble and bake as directed. Once baked, let the oatmeal cool and then slice into individual servings. Store the sliced oatmeal in airtight, heat-safe containers for up to 5 days in the in the refrigerator. Reheat the oatmeal in the microwave for 45-60 seconds, or until warmed through.
- Freeze Banana Baked Oatmeal: To freeze, I recommend slicing the oatmeal, wrapping it in parchment paper, and then freezing it in a large freezer bag. You can unwrap each slice and place it in a heat-safe bowl. Reheat it in the microwave in 30-second intervals, until warmed through.

Banana Baked Oatmeal
Ingredients
- 2 cups rolled oats quick-cook or old-fashioned
- 1-½ cups milk any variety
- 1 cup mashed bananas about 2 large or 3 small bananas
- ¼ cup maple syrup optional
- 1 teaspoon ground cinnamon
- ¼ teaspoon kosher salt
- 1 teaspoon baking powder
- 1-½ tablespoons melted coconut oil or butter plus more for greasing
- 1 large egg
- 1 teaspoon vanilla extract
Instructions
- Preheat the oven to 350℉. Grease a 2 quart or 8-inch square pan with butter or coconut oil.
- In a large mixing bowl, use a fork to mash the bananas until they are broken down and smooth. Add the milk, maple syrup, vanilla, butter/oil, egg, cinnamon, baking powder, and salt to the bananas and mix until well combined.
- Add in the oats and stir just until incorporated and the oats are coated. Let sit until the oven fully preheats, which will give the oats time to soften and absorb the milk.
- Pour the oatmeal mixture into the prepared pan and bake for 25-30 minutes, until oats are tender and moisture has been absorbed.
- Serve warm or at room temperature with additional maple syrup and chopped walnuts if desired.

Can you sub the coconut oil for Canola, olive, or vegetable oil
Kristen Chidsey
Canola oil or melted butter will work in place of coconut oil.
Nicole
I've made this a few times now and have to say it's my favorite of all the different ones I've tried. Simple. Very little prep. Delicious.
I always add walnuts. Sometimes I make several batches and freeze them.
Kristen Chidsey
Thanks for sharing, Nicole! I love to hear you enjoy this oatmeal.
Larry
Hi. Could you add walnuts into the recipe. Also, any reason why cannot be frozen?
Kristen Chidsey
Hi Larry! Feel free to add up to 1/2 cup of chopped walnuts to the oatmeal before baking. And this recipe does freeze well. You can freeze individual slices, or servings, wrapped in parchment paper in a freezer-safe bag for up to 3 months. Defrost, unwrap, and heat as desired.

Oh my goodness…This was literally the best baked banana oatmeal I’ve ever had!
Kristen Chidsey
Fabulous! Thank you so much for sharing that!
Mollie
Loved this! Brought it to the office and it was a hit.
Have you tried omitting the banana and using pumpkin purée?
Kristen Chidsey
Hi Mollie! So happy to hear you enjoyed this oatmeal! I have made this many times using sweet potato and pumpkin puree, following my recipe for Baked Sweet Potato Oatmeal 🙂 It is very similar, just adds in warming spices.
Gigi
Amazing! I love this baked oatmeal. Prepping ingredients tonight to bake in the morning for my company staying over. This will be my third time making a double batch in 9 x 13 pan. I used coconut oil and for the liquid Fairlife 2% the first time and the second time I used 1/2 Fairlife 2% and Califia Coconut Milk for the other half. Each time making the recipe, I used maple syrup as the sweetener, cutting the amount in half. This recipe will be made over and over as it is so delicious, filling and healthy.
Kristen Chidsey
I love hearing this is a staple at your house now, Gigi! Thanks for sharing and enjoy your company.

So yummy and easy to prepare! I keep it in the fridge and when it's breakfast time, heat it up and drizzle some peanut butter on top.

Roslyn
so good. Kids loved it. I used it for baby led weaning. Omitted the maple syrup and added in a bit of unsweetended coconut flakes and chia seeds. 10 month old loved it. For the 3 year old we drizzled some honey on it when served.
Kristen Chidsey
What a great idea to use for baby led weaning! I am so happy to hear your kids (and you) enjoyed the oatmeal. Thanks for sharing.
