With bananas, oatmeal, spices and walnuts, this banana baked oatmeal is a great make-ahead breakfast that will please a crowd.

So why am I making this banana bread baked oatmeal today? Well my mother-in-law loves baked oatmeal! While I enjoy it, it's something I don't ever think about making, but when browsing some recipes on Pinterest I came across a baked oatmeal recipe that piqued my interest.
Being a huge banana bread fan myself, I thought this was the perfect recipe to get me to love baked oatmeal as much as my mother-in-law and this one didn't disappoint.
The great thing about a recipe like this baked oatmeal is you make it ahead of time and just cut up and freeze until ready. But if you want even more than the recipe below makes, just double the recipe. Trust me, you'll go through it quickly.
Being the middle of summer, people are super busy which makes this the perfect make-ahead breakfast. But it's also great if you aren't busy and just want a breakfast that will lasts a few days. So give this a try and enjoy!

Recipe Ingredients
- Old-fashioned oats - don't use quick oats as texture won't be the same.
- Light brown sugar - adds sweetness.
- Baking powder - prevents the baked oatmeal from becoming too dense and heavy.
- Cinnamon, nutmeg, allspice, salt - enhances the flavor.
- Bananas - the riper the better.
- Milk - the oats soak it up.
- Egg - helps bind everything together.
- Vanilla extract - adds flavor.
- Unsalted butter - adds some fat.
- Walnuts - adds crunch.
Step-by-Step Instructions
- In medium bowl, mix together oats, light brown sugar, baking powder and spices.
- In large bowl, mash bananas.
- Add milk, 1 egg, vanilla extract and unsalted butter to mashed bananas and mix.
- Stir in oat mixture and ½ cup walnuts into liquid mixture.
- Transfer to a square 8" baking pan.
- Bake at 350°F for 30-35 minutes or until center is set. Top with remaining toasted walnuts.
Can I Use Another Type of Milk?
Yes. I've made with almond milk as well and it tastes just as good. Use whatever type of milk you desire. The flavors will be slightly different with each but the texture will be the same.
Can You Bake with Quick Oats?
Old-fashioned oats are very similar to quick oats, but quick oats have been cut smaller. As a result, quick-cooking oats cook faster, and they offer a more delicate texture in baked oatmeal. So use old-fashioned oats if you want a heartier texture.
How Long Will Leftovers Last?
You can keep the baked oatmeal in the fridge for 4 days and then reheat in the microwave. Or just keep in an airtight container or freezer bag in the freezer for 3 months.
Pro Tips/Recipe Notes
- Use old-fashioned oats so you get a heartier baked oatmeal.
- Mix together the dry ingredients in a separate bowl before adding to the wet mixture so everything gets evenly distributed.
- The riper the banana the sweeter it is which makes for great vegan banana muffins. You want a banana that has black/brown spots on the peel.
- Don’t skip out on roasting the walnuts. By roasting them they will stay crispy in the batter and bring out the flavor.
- Add ¼ cup chocolate chips to the banana baked oatmeal if you want additional flavor.

How does this do without eggs?
Ryan says
Hey Nicole,
I haven't made this without eggs so I can't speak to it, but a lot of my recipes I replace with chia seed eggs if you are trying to be vegan and those always work great. Check out how to make those here - https://minimalistbaker.com/make-chia-egg/.
