Banana baked oatmeal made with old-fashioned oats, a touch of maple syrup for sweetness, and plenty of fresh bananas and coconut flakes. This delicious baked oatmeal is perfect as a filling breakfast or healthy afternoon snack. The best part? It is incredibly easy to make and a great recipe to meal prep in advance.
Baked oatmeal is warm breakfast casserole that usually contains old fashioned oats, eggs, and milk. One of the great things about baked oatmeal, in comparison to a traditional bowl of oats, is that baked oatmeal can be prepped, baked, and then reheated. It is a great option for when you’re on the go, and need a quick healthy start to your day.

Banana Baked Oatmeal Ingredients
Eggs: these help to hold the baked oatmeal together.
Almond Milk: this baked oatmeal recipe uses almond milk but really any milk will work. Feel free to use coconut or cashew milk, or you can use a dairy milk if you prefer.
Bananas: sweet ripe bananas are the star of the show in this recipe. Be sure to choose bananas that are tender and ripe. This recipe is a great way to use up on those spotty brown bananas you have sitting on the counter.
Maple Syrup: this gives the oatmeal the perfect amount of sweetness. You can use honey if you prefer.
Cashew Butter: to keep this recipe dairy free, it uses cashew butter instead of traditional butter. The cashew butter helps to give the baked oatmeal a bit of richness. If you prefer, you could substitute the cashew butter with peanut butter or whatever nut butter you have on hand!
Vanilla Extract: any good oatmeal always includes a touch of vanilla extract.
Old Fashioned Oats: if you have a gluten allergy you will want to look for certified gluten-free oats.
Ground Cinnamon: there is a good amount of ground cinnamon in this recipe and that is on purpose. Not only do cinnamon and oats go well together, the flavor of cinnamon and bananas also pairs nicely. The cinnamon adds a delicious warm flavor to the oatmeal that I am sure you will love.
Chocolate Chips: you can’t go wrong with chocolate chips! this is an optional addition but I think that it is absolutely delicious. The chocolate chips really work well oatmeal to give it additional sweetness!
Coconut: this is another optional addition that I think just really works. The flavor of the coconut, banana, and chocolate chips all taste so good together.
How to Make Banana Baked Oatmeal
Step One: First, start by preheating your oven to 350 degrees.
Step Two: Next, it’s time to make the baked oatmeal batter. To a mixing bowl, add the eggs, almond milk, mashed banana, maple syrup, cashew butter, and vanilla extract. Whisk all of the wet ingredients together until well combined.
Step Three: Next, add the gluten free oats, baking powder, ground cinnamon, and salt to the mixing bowl and stir until everything is well combined.
Step Four: Now, fold the chocolate chips and coconut into the batter until well combined.
Step Five: Transfer the banana oatmeal batter to a 9×13 baking dish that has been well greased with coconut or avocado oil. Top with extra chocolate chips, if you like.
Step Six: Bake the oatmeal at 350 degrees for 25-30 minutes until the oatmeal is just almost set. Let it cool before slicing and serving.
Add your favorite nuts and seeds: baked oatmeal is incredibly easy to customize. Add in a few handfuls of chopped pecans, walnuts, pumpkin seeds. or sliced almonds for a little crunch.
Use extra spices: if you want to increase the spices in this recipe go for it! If you’d like to, feel free to add in a bit of extract cinnamon.
Add fruit: skip the chocolate chips and add in your favorite fresh fruit like blueberries, raspberries, or even blackberries.
Can I Use Quick Oats or Steel Cut Oats in This Recipe?
I have not tested this recipe with steel cut oats. I think that it likely could work, however, you may have to add more liquid to ensure that the texture is not affected.
Can I Make Banana Baked Oatmeal in Advance?
Option One: Because the oats will soak up all of the liquid in the batter, I do not recommend prepping the batter in advance and baking the next morning. Instead, I find it more helpful to prep all of the dry ingredients and all of the wet ingredients separately the night before.
To do this, add all of the dry ingredients to a mixing bowl, cover, and let sit on the counter. Next, whisk together all of the wet ingredients in a mixing bowl until well combined. Cover the mixture and place in the fridge.
The next day, when you are ready to make your baked oatmeal, just combine the wet and the dry ingredients, fold in any mix-ins and bake.
Option Two: The second option is my personal favorite which is to bake the oatmeal the night before and then reheat in the morning. You can reheat a slice of the oatmeal in the microwave for thirty seconds at a time until hot.
Ways to Serve
This baked oatmeal is perfectly good on its own but you can also add a drizzle of maple syrup for extra sweetness. I love to top it with fresh sliced bananas and a bit of extra coconut. You can also top a slice with a dollop of plain or vanilla Greek yogurt, fresh berries, sliced nuts, or nut butter.
How to Store and Reheat Leftover Baked Oatmeal
Store the baked oatmeal in an air-tight container in the fridge for 4-5 days.
Reheat the baked oatmeal in the microwave for thirty seconds at a time until warm or in the oven at 350 degrees, wrapped in foil, until warmed through.
Can You Freeze This Baked Oatmeal?
Yes! To freeze the oatmeal, let it come to a complete cool and then transfer to a freezer safe storage container. You can reheat the oatmeal in the oven at 350 degrees wrapped in foil until warmed through or in the microwave.
I hope you give this Banana Baked Oatmeal a try! This is so easy to make and perfect for a quick breakfast!

My family loves these so much. I make a 4x batch with whatever combo of fruit & nut butter I have on hand and add chia seeds, flax meal and hemp hearts (whatever I have on hand). My kids eat them for breakfast daily and think they are having a treat. I cook in two sheet pans, cut and freeze what they won’t eat the first couple days. Then pull from freezer, microwave for 30 seconds and they have daily warm breakfast.
My new favorite! The banana overnight oats used to be my favorite, but now this! I make them and refrigerate. I eat them all week. I do a quick 10-15 sec warm up in the microwave, and they are awesome!
Love this to make ahead and have all week!
This comes together so quickly and is delicious of course! I had all the ingredients to make this and was able to pull it together as last minute Saturday morning breakfast! Also would be a great desert!
This was so easy to make & is absolutely delicious!!!
So good! Added a zucchini for some veg, grated and squeezed out the water. Added a little more cook time for extra moisture. Served with greek yogurt and maple syrup. Breakfast all week!!
Hello baked oatmeal! Where have you been all my life? First meal of 2022 and it was the perfect way to begin the year. Thanks Ashlea for another outstanding recipe. It is so good!
SO delicious! This is the best baked oatmeal I’ve tried so far. Perfect for ready made, portable breakfast and freezes beautifully. Also a very adaptable recipe-I substituted flax seeds for the chocolate chips to cut out a little sugar 😋
I can’t believe I waited so long to try this. So easy and turned out perfect fist time. I always try to follow a recipe the first time as it is written, but I only had chunky peanut butter. I will definitely get some almond butter and use it next time. The peanut butter was ok, but I just can’t but think the almond butter would be more to my taste. Thanks for a great recipe.
I love all of your breakfast recipes, but this is my favorite one yet! Couldn’t be easier to make and SO delicious! I love the addition of the coconut!
The best breakfast prep, this baked oatmeal has the best texture! Love the little bits of chocolate chip, plus some extra peanut butter spread on top – yum!
I’ve tried a lot of baked oatmeal recipes, but this is my new favorite! It was really easy and made enough for breakfast all week. I also love that I can freeze individual portions for later. Definitely adding into my rotation for breakfast meal prep!
Happy to hear that, Erika! I’m so glad you enjoyed the recipe! Thanks for taking the time to leave a review!
This oatmeal tasted amazing and was so easy to throw together! It makes a lot, so would be good for groups or lots of leftovers. I’ll definitely be making it again!
I’m so glad you enjoyed the recipe, Theresa! Thanks for sharing!
