Baked Banana Oatmeal Recipe Base Recipe
If you’re looking for easy breakfast recipes that can be thrown together in less than five minutes, or made ahead of time for some breakfast meal prep, this baked oatmeal is for you. Full of whole grains, healthy fats, fiber and protein – a satisfying meal to keep you full for hours.
The Main Ingredients
- over ripe bananas – the spottier, the better. See notes below regarding added sugar.
- flaxseed meal – Also known as ground flaxseed. Adds a boost of healthy fats while keeping this recipe vegan. Alternatively, one tablespoon of chia seeds might also work (though I haven’t tested this).
- vanilla extract – always a good idea
- non-dairy milk of choice – Any milk will work here such as almond milk, cashew milk, oat milk, etc. If you’d like to keep this recipe nut-free, use something like soy or hemp. If you’d like a richer texture and flavor, opt for half canned coconut milk.
- rolled oats – Be sure to use rolled oats (also known as “old-fashioned oats” versus quick oats or steel cut oats. Using quick oats will make the texture too thick and steel cut oats won’t cook the same. Use gluten-free oats as needed for a dietary friendly recipe.
- ground cinnamon – for a warming spice. Brands have different flavors depending on what you get. I’ve found that store brands are spicier, while name brands (i.e. Watkins) are more mild.
- baking powder – the leavening agent to help the oatmeal rise a bit.
- fine sea salt – to enhance flavor.
The above ingredients are what will be your base recipe. You can make banana baked oatmeal using the above ingredients as is, or use any of the mix-in flavor ideas below.
Mix-In Ideas
You can flavor the base recipe in different ways, depending on what you’re in the mood for, or ingredients you have on hand.
Blueberry Banana

Walnut Banana Bread

How to Make Baked Oatmeal
Step 1 – Mash Bananas & Add Flaxseed
In a large bowl mash bananas until only small clumps remain. Add in flaxseed meal, vanilla and milk, stirring into the mashed bananas. Then allow the mixture to rest for a few minutes.
Step 2 – Add Dry Ingredients
Add rolled oats, cinnamon, baking powder and salt into the wet ingredients and stir to combine.
Then add your desired mix-ins – blueberries, peanut butter, chocolate chips, etc.
Step 3 – Transfer batter & Bake
Pour the oat mixture into the prepared baking pan. Bake for 30-35 minutes, or until edges are golden brown and middle is set.
More Flavor Combinations
You could use peanut butter or almond butter as well as add blueberries, strawberries or raspberries…
Combine chopped walnuts with blueberries…
Add just chocolate chips...
You could also do rows of each flavor on top, as shown in the pictures.
Or, leave plain and put out bowls of toppings if serving a crowd.
Double the Recipe
Doubling the recipe is easy! Just double the ingredients (you can use the scale feature in the recipe card below) and use a 9×13 pan. Bake at 375ºF for about 25-30 minutes, or until edges are golden and middle is set.
Notes about the Sugar
I opted for no added sugar in this recipe because I used very brown bananas. The more brown your bananas, the sweeter this baked oatmeal will be. If you’re using unsweetened milk and your bananas are not over ripe, I would suggest adding 3-4 tablespoons of brown sugar to bananas while mashing.
Alternatively you could add pure maple syrup, but I wouldn’t add more than 3 tablespoons. OR you could just serve this warmed baked oatmeal with a little maple syrup.
Serving Suggestions
You can serve this oatmeal immediately and portion into bowls, adding toppings like fresh fruit, your favorite nut butter, maybe some hemp hearts or chia seeds.
If you’d like to serve this baked oatmeal as bars for individual servings, you can grab and go, allow the pan to cool for about 20 minutes (chill in the fridge to speed things up) then slice and serve.
This banana baked oatmeal works great for meal prep too!
Storing Leftovers
Store any leftover baked oatmeal in the fridge, covered, and enjoy within 3-4 days for best flavor.
To freeze, place completely cooled oatmeal in an airtight container and freeze up to three months. You can also freeze individual squares.
Reheating
To reheat, allow the frozen baked oatmeal to thaw in the fridge overnight. Then you can reheat the (thawed) oatmeal in the toaster oven at 350ºF for about 10 minutes.
It can also be reheated in the microwave, for about 20 seconds per piece.
