You all enjoyed my Pumpkin Baked Oatmeal so much I immediately knew I wanted to create another flavor variation, which happens to be my favorite combo of all time: Nut butter, banana, chocolate!

It’s so easy and comes together in 1 bowl with 10 ingredients you likely have on hand right now. Let’s bake!

This baked oatmeal starts with a flax egg and mashed ripe banana. It’s then naturally sweetened with a little maple syrup, seasoned with cinnamon, and moistened with dairy-free milk and a little oil (which can be omitted or subbed with applesauce if needed).

Next comes oats, nuts, and dark chocolate! We also recommend adding a little nut butter on top for garnish to give each serving even more richness. Plus, bananas and nut butter just belong together.

After an optional sprinkle of coconut sugar for a brûlée effect, it’s into the oven for a 30 minute bake. And just like that, breakfast is on the table!

We hope you all LOVE this baked oatmeal! It’s:

Hearty
Comforting
Nutty
Reminiscent of banana bread
Naturally sweetened
& SO delicious

This would make a delicious lazy weekend brunch to enjoy with friends or family. It would also be a satisfying breakfast to bake ahead of time and warm up in the mornings before work! I think it would travel especially well in a mason jar or glass container with a little dairy-free milk to be reheated at the office!

Does it keep? 3-4 Days

Ingredients

  • 2 batches flax eggs* (2 flax eggs = 2 Tbsp flaxseed meal / 14 g + 5 Tbsp / 75 ml water)
  • 1/2 cup mashed ripe banana (the riper the better // plus more sliced banana for topping)
  • 2 Tbsp maple syrup (or sub coconut nectar or agave nectar)
  • 2 Tbsp melted coconut oil or avocado oil (if avoiding oil, sub applesauce or omit)
  • 1/4 tsp sea salt
  • 1/2 tsp ground cinnamon
  • 2 cups dairy-free milk (we used 1/2 almond milk, 1/2 light coconut milk)
  • 2 ½ cups gluten-free rolled oats
  • 3/4 cup chopped walnuts or pecans (or sub other nut or seed of choice)
  • 1/3 cup dairy-free dark chocolate chips (or chopped chocolate // use naturally-sweetened to keep recipe refined sugar–free)
  • 1-2 Tbsp coconut sugar (optional)
  • 2-3 Tbsp nut butter (optional)

Instructions

  • Preheat oven to 350 degrees F (176 C) and grease a 2-quart (or similar size) baking dish with oil (or vegan butter), or line with parchment paper.
  • Prepare flax eggs in a large mixing bowl. Then add ripe banana, maple syrup, oil, salt, and cinnamon and whisk to combine.
  • Add dairy-free milk and whisk once more. Then add oats, nuts, and half of the chocolate chips and stir to combine. 
  • Transfer mixture to the prepared baking dish and top with additional banana slices, nuts (optional), and remaining chocolate chips. Sprinkle with coconut sugar for a “swirl” effect (optional). You can also drizzle with a little nut butter — such as almond or peanut — for even more flavor (optional).
  • Bake for 30-35 minutes or until the top is golden brown, the edges are slightly caramelized, and it has some springiness in the center. Remove from oven and let cool a few minutes.
  • Serve warm with desired toppings, such as warmed coconut milk or almond milk and a drizzle of maple syrup or additional nut butter.
  • Store leftovers covered in the refrigerator 3-4 days (or in the freezer up to 1 month), though best when fresh. Reheat in a 350-degree F (176 C) oven or in the microwave until hot, adding more dairy-free milk as needed to moisten.

    I made this today and I love it! I didn’t have enough oats, so I used 2 cups oats 1/2 cup quinoa flakes. Didn’t have any nuts either so I had to (sadly) leave those out. I used almond butter for the topping and will definitely add more next time. I really like how it came out, so I think I’d continue the oats/quinoa flake combo the next time I make this. Delicious! (Also I saw someone else’s comment about using blueberries instead of chocolate chips – I think I’ll try that too). I can definitely see myself making this again and again. Spoonie approved!

  2. Katie says

    Made this this morning with some substitutions: I don’t care much for banana so I replaced the mashed banana with applesauce and then did blueberries instead of chocolate chips. I initially cooked for 35 minutes but wanted the oats to be a bit more well done so ended up doing 50 minutes total. Super tasty, loved the blueberry + cinnamon + almond butter combo. Will be repeating this one.
    Thanks as always! Ya’ll are my go-to recipe source and I always recommend this site for people interested in cooking more plant-based.

      We’re so glad you and your family enjoyed it, Mariham! Thanks so much for the lovely review!

  3. Kris says

    I just made this for breakfast and it was a hit with the family. It turned out moist and not too sweet. I used 2 flax eggs and subbed applesauce for oil. I didn’t add nuts but definitely chocolate chips. I loved that it was simple and quick to make. Would make it again. Thank you!

  4. Vicki says

    Easy to make and delicious… especially if you accidentally dump in ALL the chocolate chips and then get more for the top. :)

  5. Carole says

    Wow! So good. Was easy to make and delicious!
    I added a ¼ cup of coconut as we love coconut in our home. Love your recipes.
    Please keep posting ❤️

  6. Panos says

    I’m looking forward to trying this recipe! I think there is a mistake with the metric ingredients as it mentions
    12-24 Tbsp coconut sugar and 32-48 Tbsp nut butter (optional) :O

  7. Carolyn says

    This is a really yummy recipe. My family all LOVES it! I make it without the nuts and chocolate chips since I have different food allergies in my family, but for those who can have it, we sprinkle the chocolate chips and almond butter on individual servings when it’s still hot from the oven. My girls ask for this every time they have friends over. Thanks so much!

  8. Mira says

    Thank you Dana for making this recipe easily halved!

    I made quite the mistake not using a pan with a larger surface area because the crust that forms is so so SO yums! I wanted to just scrape off the entire top and call it breakfast but I’m a (sort of) responsible adult and only had 1 serving. I want to say that it’s a rather rich breakfast especially if you top it off with a nut butter but it’s filling in a way that makes you satisfied and not overly bloated and groggy. The serving may look small but she’s mighty (and delicious. Did I mention that already?)

  9. Lori says

    Hi Dana, another awesome recipe :) made exactly as written including the optional toppings. Silky texture inside and an nice crust on the outside and all that melty chocolate…yum !! Not at all sweet but tastes so good just the way it is. I didn’t add any maple syrup to mine just a dab of yogurt. I said to my husband this would be delicious for dessert with some vanilla ice cream. Thanks for another terrific recipe Dana. I’m going to try the apple ginger sauerkraut next, it looks amazing :)

  10. Darcie Clark says

    I made it this morning and will have delicious baked oatmeal for my husband and me for several days now. Yay! I subbed the chocolate chips for 1/2 cup blueberries and put in half pecans, half walnuts for the nuts. Dollops of peanut butter and sliced banana on top before baking made this extra tasty. Thanks for a most comforting recipe at this time!

  11. Diana says

    I have made this a few times now and I love it.
    Especially when you are busy, its so easy. Just make it the night before and in the morning, you just heat it up (I add some almond milk or almond yoghurt) and more blueberries.
    It lasts me about 5 days.
    I love it so much, its tasty and healthy!

  12. Ariane says

    I made this recipe, and it is absolutely delicious! However, I did not have any maple syrup, so I used coconut sugar instead. I will definitely be making this again!

  13. James Zwolak says

    Have been eating this for breakfast everyday for awhile! Very tasty! Freezes well and reheats perfectly. I made some edits leaving out the salt and trying to reduce sugar. It’s not as good as the original recipe, but it certainly hits the spot!

  14. Mara says

    Love the recipe. I actually used regular milk (I’m not vegan), and used regular milk chocolate chips (all I had on hand), and it turned out superb! Thanks for all of the great recipes.

  15. Jessie says

    Delicious – despite intentional and unintentional modifcations!
    **Intentional changes: Increased bananas and cinnamon by 50%, no chocolate chips, added 2 tablelespoons ground flaxmeal, substitute 2 whole eggs for flax eggs.
    **Unintentional change: FORGOT THE EGGS! Found them resting whole on the counter as I slid the pan into the oven. DOH!

    Peanut butter drizzle = A+! This is delicious – I look forward to making it again WITH eggs! Next time I’ll increase the salt, it could use a bit more flavor enhancing.

  16. Dawn says

    This is so yummy!! I’ve made this recipe 3 times this week because it keeps getting eaten up. I mixed peanut butter into the mixture as well as on top per my husband. Can’t go wrong with peanut butter, chocolate, oats and bananas!

  17. Diana says

    This was so tasty! I happened to have everything on hand when I saw this recipe so I decided to give it a try. I think maybe a little bit more salt may have added to the flavor. My husband likes to drizzle some honey on it to make it sweeter but I think it’s perfect!

  18. Ashleigh says

    Can the flax eggs be swapped for real eggs? I can’t seem to find flaxseed meal anywhere.
    I am planning to make this for breakfast soon, looks delicious!

    • Avatar for Dana @ Minimalist BakerSupport @ Minimalist Baker says

      That should work! 1 flax egg generally = about 1 small chicken egg. Let us know if you give it a try!

  19. Bernadette says

    I love how easy, healthy and tasty this is! Perfect if you need a more substantial breakfast to go! Pair with peanut butter and you are all set! Love this as a snack too! My boys enjoy this as much I do :) Thank you!!!

  20. Julie S. says

    I made this for breakfast when we had houseguests over. It was super easy and was delicious. We topped with melted cookie butter to splurge a little bit.

  21. Cassie Autumn Tran says

    This looks to die for! I LOVE baked oatmeal and I would totally love to create some myself <3 Banana bread is, additionally, one of the BEST flavors for oatmeal and any porridge recipe!

  22. Elise Takahashi says

    Hi there,

    I just made this last night and it was a HIT with my boyfriend and I. I then decided to bring some for my friends at work…and needless to say I might be getting a raise! Its incredibly delicious and comforting and just SO GOOD!

    Also- I had the container sitting out on the counter as I was warming some up and a co-worker was like “OMG is that Minimalist Bakers recipe?!” You have many fans in our office!

    I’m thinking of bringing it to my boyfriends parents house on Saturday for Sunday brunch. Do you think I could make it Saturday and keep it in the fridge to bake off Sunday morning? Let me know!

    Thanks so much!

    • Avatar for Dana @ Minimalist BakerSupport @ Minimalist Baker says

      Hi Elise, so glad to hear this- thanks for sharing! Yes, it can definitely be prepped the night before and baked in the morning!

  23. Lola says

    I made this with avocado oil, cow’s milk, no nut butter, and extra chocolate chips (half a cup or so) and it’s so good (even when cold)!

    • Avatar for Dana @ Minimalist BakerSupport @ Minimalist Baker says

      Hi Debbie, we haven’t tried that, but it might work! You may want to use more liquid or try a smaller batch to test it out. Hope that helps! If you give it a try, we would love to hear how it goes!

  24. Nicole says

    I was out of cinnamon so I used nutmeg and it almost did the trick but not quite. I also sliced my bananas pretty thin and they were fairly dry when they came out of the oven so I suggest thicker slices for the topping. This wasn’t really my cup of tea but I can see why folks who really like oatmeal would dig this recipe.

    Still <3 all things Minimalist Baker!

  25. Skata Rae says

    This was excellent – made it for my entire (non-vegan) family for breakfast after a sleepover get together. They all loved it and had more than 1 serving!

  26. Sarah says

    Followed the recipe exactly… maybe adding a few more chocolate chips. Yum! A quick and easy recipe for the work week!

  27. Nina Javez says

    OK I am most definitely making this for a potluck dessert, it is TO DIE FOR! Almost like a bread pudding! thanks so much for sharing

  28. Heidi says

    This was super yummy, my kids & husband ( who usually doesn’t like oatmeal) loved this! I made modifications, but used the recipe as a base. I used honey instead of syrup, powdered milk, omitted the chocolate chips, added grated apple and bit of shredded coconut, topped with banana & pecans. Baked for about 30 minutes, realized I forgot to drizzle with peanut butter, added it, then baked another 5-10 minutes.
    We served it with yogurt, shredded coconut and cinnamon!
    Next time I will also add frozen blueberries!

  29. Heather says

    I made this yesterday and it’s fantastic! I skipped the coconut sugar and nuts but otherwise followed the recipe. I used Oatly and gluten-free quick oats as well.

    Topping with banana slices is absolutely a must! I will definitely be making this again.

  30. Emily Kogel says

    I used 3x the mashed banana the recipe calls for (1.5 cups), halved the non-dairy milk (1 cup), omitted the oil, and used quick oats instead of rolled. It came out perfectly! Thanks for a quick, delicious, healthy breakfast that I can go to every morning this week!

  31. Colleen says

    New way to get my oats in, made it exactly, except I put all walnuts. I did not add the coconut sugar, but I will next time. Sent some to work for my hubby’s breakfast. Winner! So delish, thanks for sharing.

  32. Pam says

    I live alone so I modifies the recipe a bit so I would have just a single serving. I microwaved the oats, flax and banana then stirred everything else in. Yum! I might have added a few too many chocolate chips but what the heck? It’s Sunday breakfast.

  33. Ellie says

    I would love to make this an many of your other recipes, but I have a nut intolerance. Many of your recipes require nuts or nut butters. Can you omit tremor do you have ideas for substitutions?

      • Colleen says

        You could skip the nuts, and the nut butter, chopped apples would be awesome in this dish, and I think raisins too. Actually going to try this as well.

        • Avatar for Dana @ Minimalist BakerDana @ Minimalist Baker says

          Lovely suggestions, Colleen! Any seasonal fruit or your favorite seed/seed butter would do!

  34. Jana says

    This is so stinking good! I didn’t do any extras – just the main mix of oats, bananas, maple, chocolate chips, etc. (but I used chicken eggs) – super tasty and doesn’t need anything beyond a splash of non-diary milk. I’ve been heating it up all week at work and it’s such a delicious treat for breakfast, and under 400 calories per serving!

  35. Caroline says

    You’ve done it again! You created another recipe that’s filled my belly with happiness! I made this today and the only change I made was that I omitted the chocolate. I’m always telling my daughter chocolate isn’t for breakfast so I have to abide by those rules too ;) It’s absolutely delicious and it feels pretty decadent because it’s like eating banana bread for breakfast. I can hardly wait until tomorrow morning for more! The recipe is so easy and so delicious that it will be added to my regular roster of breakfast plans, like so many of your recipes. Thank you!

  36. Evelyn Mackiewicz says

    I made this last night as my breakfast meal prep for a few days. Instead of using oil or apple sauce in the recipe, i just added extra mashed banana and used only almond milk. I forgot to add sliced banana as the oatmeal topping, but it still came out delicious and I’m adding fresh banana on the side. 30 seconds in the microwave this morning warmed it up to perfection and it was great alongside my coffee. Thank you for this easy recipe; as someone with Hashimoto’s, sometimes I don’t have the energy to spend a lot of time in the kitchen prepping to cook and washing all the pans afterward. I dirtied one bowl for prep, one fork for mashing/stirring, and one pan for baking (which I’m leaving the oatmeal in as I consume) so this was a perfect recipe for me. I think next I’ll try this same base but half/half light coconut cream with almond milk, blueberries, and lemon zest for a different variation.

  37. Helen says

    We all loved this including my toddler. I was looking for easy, but good, make ahead breakfasts and this was perfect. I used real eggs, left out the chopped nuts because the toddler isn’t ready for them and instead included melted nut butter in the mixture itself. Made it the night before and it came out great although I had to bake it longer since it was cold to start.

    Thanks so much. Can’t wait to try the pumpkin one.

  38. Shene says

    This beautiful and yummy dish as my home smelling a wonderful bakery. The smelled stirred up childhood memories when my mom use to bake on Saturday mornings. What a wonderful treat! So delicious! I am going to make this often!

  39. Mahika Mehta says

    I am not an oats fan, but this recipe quickly changed that! I used Muesli instead of oats only, since I already had it in my pantry. We ate it right out of the oven as dessert with some crunchy almond butter and 2% milk, and absolutely loved it. It’s the perfect amount of sweet. We plan to have this for breakfast for rest of the week. Thanks for this amazing recipe. Will definitely remake it.

  40. Chandni says

    So delicious! I didn’t have flax seeds so I subbed for chia eggs and it came out great (I didn’t have regular eggs at home either). I used coconut milk, cashews, and dark chocolate chips for my recipe. I ended up using rolled oats, because that is what I had on hand. I didn’t have an issue with baking, since I let the mixture sit overnight. The oats softened enough to cook perfectly in the oven for 30 minutes. I topped the oatmeal with chocolate chips, cashews, cinnamon, almond butter, and sugar. I’m eating a serving right now and it is delicious. I love that I have a few portions that I can vary a little each day, but keep the same delicious base!

  41. Helen says

    Wow, you put this all in one bowl? I’m amazed! Usually I would have eaten my oatmeal and its toppings in multiple, smaller separate bowls. I find this really helps with my mindful awareness for the day and also to loosen my IBS. But putting many things in just one bowl is just amazing. I can’t wait to try it!

  42. MaLea says

    This just came out of the oven at 7pm in Singapore. I’ve had a taste and wow, it’s delicious! I subbed honey for maple syrup as I’d run out. For the nuts I used a mixture of walnuts and almonds. And for chocolate I roughly chopped 90% dark chocolate (I like my chocolate really dark). The coconut sugar was a really nice touch! I love that this baked oatmeal isn’t too sweet – exactly how I like my food. Thank you for a great recipe!

  43. Karson says

    Could quick cooking oats be used for this?? It looks delicious, but I live in South America and quick oats are the only I can easily find.

  44. Nancy says

    Just made this and had it for breakfast. Very easy and very yummy! I used the applesauce instead of the oil, spooned some peanut butter and sprinkled 1 TB coconut sugar on the top before baking. Plenty sweet. Ate it with some warmed up non dairy milk. Highly recommend!!!

  45. Sarah says

    I’ve never been a fan of oatmeal, yet was intrigued by baked oatmeal as I love to bake. This was delicious and so filling! wow! I love the banana chocolate combo and I added pb onto it after it baked. I subbed applesauce for the oil as I had some to use up.
    A great lazy Sunday morning breakfast to make and now I have lots for the rest of the week too. Another fantastic recipe! Thanks!

  46. Rachel Muir says

    Loved this recipe! So easy and satisfying, esp with the nut butter! Also love the leftovers :)

    10/10

  47. Nora says

    Yum! Another winner. Baked mine for 40 minutes because I like my oatmeal on the drier side. So looking forward to eating this all week – thank you!

  48. Cynthia Garofalo says

    Delicious Sunday breakfast with leftovers for the week. It was easy to make and even though I am not Vegan and made with regular eggs, it came out great. Definitely a keeper! Thanks Dana.

    • Avatar for Dana @ Minimalist BakerDana @ Minimalist Baker says

      Susan, you can try that but I suspect you’ll need to increase the liquid : oats ratio (more liquid), try covering it while it bakes, and bake longer as steel cut oats require more time to cook through. Let us know if you give it a try!

  49. Melinda says

    This looks wonderful! I have a work breakfast coming up and I was wondering if this would be something I could put together the night before, then bake early the next day. Thoughts? Thank you for all your wonderful recipes! We make your meals at least 4 out 7 days a week! ❤️

    • Lara says

      I prepped her pumpkin baked oatmeal overnight and it turned out perfect. I’ve also experimented and have done a cinnamon/apple/walnut version. So good. The morning I bake it I just add a splash of almond milk to the top.

      • Avatar for Dana @ Minimalist BakerDana @ Minimalist Baker says

        Thanks for sharing, Lara! Yes, it can definitely be prepped the night before and baked in the morning!

    • Amanda says

      Did you end up trying this? I would think maaaaybe it might need a bit more liquid as it would all be soaked up by morning and that would be the point of the baking?
