This peanut butter banana baked oatmeal is moist, fluffy, and incredibly delicious! It’s a vegan and gluten-free breakfast made with healthy ingredients like overripe bananas, rolled oats, and creamy peanut butter. Enjoy this oatmeal bake as a nutritious weekend brunch or for meal prep throughout the week!
You may have tried my chocolate banana baked oatmeal, but today I’m bringing you peanut butter banana baked oatmeal. It’s like the older, less rebellious sister. You know what I mean? No? Just me?
This recipe is my new favorite breakfast. Ok, I think I declare something as my “new favorite” every week. But, I can say with certainty that – at this very moment – it’s my favorite. I don’t foresee this opinion changing any time soon. I ate this breakfast for the last week straight, and that says a lot for someone who isn’t a creature of habit!
So, what’s this baked oatmeal all about? Well, for starters, it’s vegan and gluten-free. No refined sugar is used in the recipe. The flavor is lightly sweet with hints of vanilla while the texture is fluffy and moist. The banana flavor is not too over powering and each bite contains creamy peanut butter.
Oh, and let’s not forget – it’s a great option for meal prep because you can store leftovers in the refrigerator for up to four days. Simply reheat a slice by popping it into the microwave for 30 seconds!

This recipe is very easy to create! All of the ingredients can be mixed together in just one bowl. Round of applause for the easy clean-up process, right? Let’s get started!
First, we’ll mash the ripe bananas. The recipe calls for 1.5 cups which is approximately 4 medium-sized bananas. I recommend measuring to get the exact amount.
Next, add creamy peanut butter, maple syrup, applesauce, melted coconut oil, vanilla, cinnamon, and salt. Mix the ingredients together. Add almond milk and mix together again until well combined. Finally, fold in the rolled oats and baking powder.
It’s now time to assemble the batter and toppings. Pour the batter into a lightly oiled baking dish. Then, add your desired toppings. Bake at 375 degrees F for 40 minutes or until a toothpick comes out clean.
We’ve reached the finish line! After allowing the peanut butter banana baked oatmeal to cool, slice it into 12 squares and serve. It pairs great with a cold glass of almond milk. Also, feel free to add additional sliced bananas and peanut butter on top. Mmmmmmm.
- Use ripe bananas! You may be wondering how to tell if your bananas are ripe enough. The answer is simple; a ripe banana will have a yellow peel with small brown specks all over it. Ripe bananas are sweet and perfect for baked oatmeal, banana bread, and banana oatmeal cookies.
- Got toppings? This peanut butter banana baked oatmeal is delicious all on its own, but I love tossing some additional banana slices, creamy peanut butter, and hemp seeds on top. Also try: berries, walnuts, pecans, chocolate chips, or this insanely delicious maple almond butter. Seriously – I ate a slice drizzled in maple almond butter for a week straight after making this recipe. Sooo good!
- Rolled oats work best. I recommend sticking to rolled oats instead of trying to substitute quick oats.
- Keep any leftovers stored in the refrigerator to maintain freshness. The leftovers should keep for 3-4 days. To reheat, warm in the microwave or oven at 350 degrees F.

Love this recipe!
I’ve made it several times now, usually with a few minor modifications, and it always comes out great.
Thank you for an easy-to-make, tasty breakfast option!
Thank you so much, Alicia! I’m so happy to hear you love this recipe 🙂 Since you’re really enjoying this one, I highly recommend checking out the Chunky Monkey Baked Oatmeal too!!
I’m out of coconut oil— do you suggest any substitutes?
Since it’s just 1 tbsp, it should still work fine without it 🙂
Can I sub the applesauce for anything ?
Hi, Nika! Since only 2 tbsp are used, you should be fine just omitting it from the recipe 🙂
What are your thoughts on making this the night before and baking in the morning? I wonder if the bananas might oxidize and change in flavor 🤔
I haven’t tried it, but I also think the bananas would oxidize and, therefore, change in flavor/texture/appearance. If you want to make it ahead of time, bake it and then store it in the refrigerator inside an airtight container after it has cooled. In the morning, you can simply reheat however many slices you want to serve. Just pop them in the microwave or oven 🙂 I’ve done this many times and it works well! I love adding peanut butter on top, too!
Will try it soon sounds real good as my husband is a diabetic and he gets tired of eating oatmeal the same way
Hope you both love it, Lynn! Let me know once you try 🙂
