Recipe Ingredients Needed
All you need to make this oatmeal breakfast bake are 10 simple, healthy ingredients:
- rolled oats
- baking powder
- cinnamon
- salt
- almond milk
- vanilla extract
- bananas
- walnuts
- peanut butter
- dark chocolate chips
Recipe Modifications & Ingredient Swaps
While this vegan oatmeal recipe tastes delicious as is, here are some easy ways you can modify this recipe to suit your needs:
- Instead of peanut butter, try this with another nut butter like almond or cashew butter. I made it with almond butter too, and I LOVED it!
- I used almond milk for this recipe, but feel free to swap that with your milk of choice (cow’s milk, soy milk, cashew milk, etc.) My only advice is to choose one that’s unsweetened.
- If you don’t have walnuts, you can easily replace them with pecans – they’ll taste just as good. A sprinkle of coconut chips on top would also taste divine!
- For a nut-free version, you could try swapping the peanut butter with sunflower seed butter instead. As well, omit the walnuts on top.
- If you follow a strict gluten-free diet, be sure to use certified gluten-free rolled oats.
- If you’re a strict vegan, make sure to use vegan (dairy-free) chocolate chips. I like these ones!
How To Store & Reheat Baked Oatmeal
While it tastes best straight from the oven, baked oatmeal can be an excellent addition to your weekly breakfast meal prep routine!
Baked oatmeal can be stored in an airtight container in the fridge for 4 days. If you’d like to further extend the shelf-life of baked oatmeal, it can be stored in the freezer for up to 6 months.
The easiest way to reheat baked oatmeal is in the microwave.
TIP: You may find that the leftover oats have absorbed more of the liquid over time, making them a bit dry. Simply add a splash of milk of choice and give it a stir before reheating!
Peanut Butter Nutrition Benefits
Peanut butter is an awesome source of heart-healthy fats and plant-based protein.
It’s also packed with other nutrients like:
- magnesium
- vitamin B6
- iron
- phosphorus
- niacin
TIP: be sure to go for the unsweetened variety of peanut butter. I always look for brands where the only ingredient is peanuts!
Banana Nutrition Benefits
Bananas are a great source of fibre – one medium banana provides 3g of fibre
They’re also a good source of micronutrients like:
- potassium
- vitamin C
- vitamin B6
- magnesium
Oatmeal Nutrition Benefits
Rolled oats are a great source of dietary fibre and plant-based protein.
Oats contain a ton of B-vitamins, like thiamin, folate, and pantothenic acid.
They’re also packed with essential minerals, like:
- manganese
- phosphorus
- magnesium
- copper
- iron
- zinc

Super easy and my kids loved it!!
Hi Debby! Thanks so much for sharing your experience – I’m so happy you loved it and that it was kid-approved 🙂
So good, Carrie! I really love the mouth-feel of baked oatmeal (your scrumptious pear baked oatmeal was my introduction). The recipe flavors and texture of add-ins make it a breakfast I’ll definitely be putting on repeat. I used some toasted coconut almond milk mixed with straight up coconut milk because that’s what I had on hand, which inspires me to add grated coconut next time. And some flax seed–because it’s a simple way to get my Omegas in. Thanks for providing such a great start to my day, Carrie!
Hi Susi! Yay I’m so so happy to hear that you’ve found a love for baked oatmeal through my recipes :). Thank you so much for sharing your experience as well as all the yummy additions you made. Sounds so good!!
PS. I think you would LOVE my pineapple baked oatmeal – it’s soo tasty during the summer months!!
Easy and delicious 🤤 🤩
Thank you so much, Ray!!
Can I make and freeze, before baking, in smaller containers OR will it loose its consistency?
Hi Laura! Thanks so much for your question. I have not personally tried freezing the oatmeal mix before baking, so I’m not entirely sure if that will work. That said – you can definitely bake the oatmeal and then freeze leftovers in smaller portions! I hope that helps 🙂
Yum!!! I made this yesterday to eat for breakfast the next few days. Even my fiancé who despises oatmeal said he liked it and would eat it again! I used what I had on hand, which was frozen (thawed) bananas, Ripple pea-protein milk, reconstituted PB Fit peanut butter powder, semi-sweet chocolate chips, and pecans instead of walnuts. I also halved the recipe, but the cooking time remained the same. Thanks for the great recipe as always, I’ll definitely be making this again.
Hi Anna! Thanks so much for sharing your experience and all the additions you made! I’m so happy to hear that both you AND your fiancé enjoyed this one!! Hopefully we have an oatmeal convert haha. If he liked this one, there are some other baked oatmeal recipes on the site that he might enjoy as well!! Can’t wait to hear what you try next 🙂
Love this recipe! It was easy and made enough for a few days. Reheated well! Yum!
Look forward to trying more of your recipes.

Hi Kianna! Thank you so much for sharing – I’m so happy to hear you enjoyed this one. I look forward to seeing which ones you try next 🙂
Hi! Loved seeing this recipe and so excited to try it. Could you please tell me how many calories it will have per serving?
Hi Fatima! I’d love to know if you do!!
I don’t count calories and I intentionally choose not to include the exact nutrition breakdown of my recipes. Ultimately, focusing on numbers goes against my nutrition philosophy as a dietitian and I much prefer to highlight the various health benefits of the whole food ingredients that I use! That said, if you would like to calculate the nutrition breakdown you can always enter the recipe into a nutrition calculator like MyFitnessPal! Thank you for understanding <3
Made this exactly as the recipe stated except that I used regular milk instead of almond, making it not vegan. It turned out amazing. The combination of flavours – banana, peanut butter and chocolate chips were a winner. Not too sweet, healthy and fills you up. Everyone needs to make this… It’s so easy!
Hi Sher! Thank you so much for the kind review!! I’m so happy to hear you enjoyed this and that you found it easy to make. You can’t go wrong with banana, PB, and chocolate, right hah?! I’d love to know if you give any of my other baked oatmeal recipes a try! Thank you again 🙂
Second time making this. It is sooo delicious!
Yay!! I’m so happy to hear that you enjoy it, Jossira. Thank you for sharing that 🙂
Excellent. Just came out of the oven and my husband put coconut whip cream and it was wonderful. We did add raisins too.
Hi Loni! Thank you so much for sharing your experience – it’s so appreciated! I’m so happy to hear you enjoyed this recipe. The coconut whipped cream on top sounds AMAZING!!!
Hello! Looking for a kid-friendly healthy breakfast and this looks to fit the bill. My kids love chocolate chip banana bread. But can I sub unsweetened milk for sweetened? Either original soy milk or almond milk. Just to make it a little sweet? Or does it make it too much sugar?
Hi Jackie! Thank you so much for your question. I think this would be a hit with kids 🙂
You could totally sub the unsweetened milk for sweetened, from a technical perspective! For myself personally, I find the cooked bananas and chocolate chips sweet enough, but it’s really up to you. Instead of dark chocolate chips, you could also do semi-sweet. Another option would be to add maple syrup when serving, so the kids can get it to their desired sweetness! I hope that helps!!
This baked oatmeal was absolutely delicious and really hit the spot. Not too sweet and a wonderful combination of flavors. Although we didn’t use walnuts this time, I’m looking forward to seeing how they taste with it next time! Also really excited to try your pear oatmeal bake in the future. Thanks for providing a bit of comfort in a bowl on a chilly day!
Hi Aimee! Thank you so much for taking the time to leave this kind review. It’s so helpful and appreciated!! I’m so happy to hear that you enjoyed this one, and I hope you love the pear one too! Baked oats are seriously the best when it’s cold out 🙂
This looks absolutely amazing! Could this be prepped the night before and popped into the oven in the morning?
Hi Kristin! Thank you so much for your question and kind words!
I have (oddly enough) never thought to prep baked oats the night before, so haven’t personally tried it! But I did a quick google search and it does seem that baked oats can be prepared the night before. You can mix everything together in the baking dish, then cover and keep in the fridge overnight. Be sure to give everything a good stir together before baking as the ingredients may have separated. And of course, any toppings should be added right before baking! I hope that works 🙂
Delicious! I added raisins. I also used roasted pecans, A dollop of Greek yogurt and granola, and apricot preserves on top. Thanks for the recipe!
Hi Sherri! Thank you so much for taking the time to leave a review, it’s so appreciated. I’m so happy to hear that you enjoyed this one. Love all the delicious additions you made – those apricot preserves, yum!!
I look forward to future recipe ideas! Do you do smoothie ideas as well???
So happy to hear that, Sherri 🙂 I do! You can explore all my smoothie recipes HERE!
