Baked oatmeal is such a great way to start the day! High in fiber and protein, this breakfast will keep you feeling full until lunchtime. Not only is it good for you, but it tastes so delicious – peanut butter and banana is such a classic combination! My kids thought it was dessert when it was baking in the oven!

Ingredients

  • Oats: Use old fashioned oats for this recipe. Oats are a great source of fiber and vitamins. Use gluten-free certified oats if you have an intolerance.
  • Cinnamon: To add a little sweetness and flavor.
  • Baking powder: This helps t add a nice light texture to the oatmeal.
  • Bananas: Use overripe bananas. They are naturally sweeter and richer in antioxidants.
  • Almond Milk: I used almond milk to keep this breakfast vegan. You can use another non dairy milk or dairy ilk if you prefer.
  • Peanut butter: Use creamy peanut butter for the best texture.
  • Maple syrup: To naturally sweeten the oatmeal.
  • Ground flaxseed: Helps to bind the ingredinets together without the use of eggs.
  • Vanilla extract: For flavor and sweetness.

How do you make banana baked oatmeal

Start by mashing two ripe bananas in a bowl. Then add the wet ingredients on top, including the peanut butter, maple syrup, ground flaxseed (which combined with liquid replaces the egg) along with almond milk. Mix it all together until well combined.

Put the dry ingredients including the oats, cinnamon baking powder and salt, into a baking dish like this one and whisk them together with a fork. Pour the wet on top of the oats mixture and stir to combine.

Bake in a pre heated oven until the mixture is set.

When it comes out of the oven, you’ll notice the sides of the baking dish are browned and the banana baked oatmeal pulls away from the sides. That’s when you know it’s done! I love to add a drizzle of peanut butter and some banana slices to serve the oatmeal…delicious!

Tips for making banana baked oatmeal

  1. Use old fashioned oats for this recipe. Quick oats are chopped into finer pieces, which makes them faster to cook. Although they taste the same as rolled oats, the texture of quick oats is much finer, so they soak up more moisture and can dry out the baked oatmeal.
  2. Do not mix the oats with milk ahead of time. If you want to prep the recipe halfway before baking, you can mix the wet ingredients in one bowl and the dry ingredients in another bowl. Just don’t combine them until you’re ready to bake. Otherwise the oats will soak up all the liquid and yield a dry texture.
  3. Add more liquid for a softer consistency. The consistency of this is almost like a dense muffin but I like that it stays compact that way. If you feel the consistency is too dry, feel free to add 1/4-½ cup more milk.
  4. Double the recipe for a bigger crowd. If you double this banana baked oatmeal, use a large baking dish and just add 10 minutes to the baking time.
  5. Did you know it’s really easy to make your own peanut butter?!

Frequently asked questions

Can I make this with steel cut oats.

Sure, but the exact measurements and time will differ, so check out my baked steel cut oatmeal recipe instead.

Can you use any milk for baked oatmeal?

I use almond milk for this vegan breakfast, but it will work well with any dairy or non dairy milk. The flavor of coconut milk would work really well with the peanut butter and banana, and oat, soy or hemp would all be good substitutes. To keep this recipe vegan, I used maple syrup for the sweetener, but if you are not vegan, you can use honey instead if that’s what you have.

How long can you store it?


Baked oatmeal is perfect for breakfast meal prep. I often make a double batch on a Sunday to enjoy throughout the week. Store the cooled oatmeal bake in the fridge in an airtight container and it will keep well for up to 5 days. I like to then reheat individual portions in the microwave for about 30 seconds before serving.

Can you freeze it?

This banana baked oatmeal freezes really well, and will keep in this way for up to 3 months without affecting the texture. Wrap the oatmeal in individual portions in a foil and place in a freezer bag. Thaw it in the fridge overnight and reheat with a tablespoon of milk or water in the microwave.

  1. Love this recipe! Tried it for the first time and was so happy with the results. I used almond butter instead of peanut butter. Thank you for sharing this recipe!

  2. Hi Yumna,
    Thank you for the recipe. Very yummy. My question is, do the calories that you posted include the drizzled peanut butter & banana topping?
    Thank you, Sonia

    1. You’re so welcome! Yay!! The nutritional data does not take into consideration the toppings.

    1. Yes! This banana baked oatmeal freezes really well, and will keep in this way for up to 3 months without affecting the texture. Wrap the oatmeal in individual portions in a foil and place in a freezer bag. Thaw it in the fridge overnight and reheat with a tablespoon of milk or water in the microwave.

    2. This is such an easy, healthy, and, if you premake, a grab-and-go breakfast recipe! It makes my morning rush easier when this is in the fridge. Thank you!

  3. Do you think you could add chia seeds to this too? Would it need extra liquid? Obsessed with this recipe and a huge bonus that it’s toddler approved- thank you!!!!

    1. It’ll depend on how many chia seeds you’ll use. If you add 1-2 tablespoons, I don’t think you’ll need extra liquid! So happy it’s toddler approved too!

  4. Excellent breakfast! I made this for myself for breakfast this morning, and it’s DELICIOUS! I used unsweetened coconut milk and Erythritol for the sweetener. also I used a chai spice blend instead of cinnamon…oh man it’s so good and the smell of it baking…heaven! Great recipe, thanks for sharing! I drizzled some Torani dark chocolate sauce over it and ate it warm… so good!

  5. Made this twice now and love it! Such a great on-the-go breakfast or snack. The topping makes all the difference–you can stick with plain PB, or my favorite is to mix some PB, honey, and a bit of almond milk to make a sweeter drizzle. Dark chocolate chips work great too!
