I thought it would be fun to kick off the New Year with a new baked oatmeal recipe that’s perfect for all your healthy eating goals. No matter how much you indulged over the past few weeks (or months!) you can always decide to make a change. Start with one small change… like eating a healthy breakfast every day!

Why is Eating Breakfast Important?

Breakfast is often deemed the most important meal of the day? Isn’t it funny that it’s probably the most skipped meal of the day? So why is it so important anyway?

  • Kick start your metabolism – The earlier you eat in the day, the more calories you’ll burn! Seriously.
  • Energy – Food=fuel. Eating breakfast will give you energy to get important tasks done all day long.
  • Concentration – Do you notice that you can’t focus on anything but food when you’re hungry? THAT is why eating breakfast improves concentration throughout the day!

Peanut Butter Banana Baked Oatmeal Recipe

I sound like a broken record but this recipe is so simple to make! Start by mixing the dry ingredients together in a large bowl. Mix in the wet ingredients as well as two sliced bananas. Stir well to combine everything. Pour the mixture into a baking dish that has been sprayed with cooking spray and top with additional banana slices. Bake until golden brown, drizzle with more peanut butter and enjoy! You just made the best gluten-free, dairy-free breakfast around. 😉

Can You Make Baked Oatmeal Ahead of Time?

Yes, you can totally make baked oatmeal ahead of time. There are two options that work really well.

Option 1: Bake and Then Reheat Before Serving

  1. Prepare baked oatmeal as the recipe suggests. Once baked, let the oatmeal cool, cover the baking dish and place in the fridge. You can do this 1-2 days in advance.
  2. When you’re ready to serve, take oatmeal dish from fridge, cover with foil and reheat in a 350°F oven for about 20 minutes. For individual portions, set toaster oven to 350°F and bake for 5-10 minutes or reheat in the microwave for 1 minute.

Option 2: Prep as Much as You Can Without Baking

  1. Mix together your dry ingredients in a bowl, cover and let sit out on the counter until morning.
  2. Mix together all the wet ingredients in another bowl, cover and store in the fridge until morning.
  3. In the morning, simply mix the wet and dry ingredients together, pour oatmeal mixture into your prepared baking dish and bake as recipe suggests.

    1. I usually buy store brand natural peanut butter… ones with only 1-2 ingredients (peanuts + salt), I like Kroger Simple Truth PB or the store brands from Target, Trader Joe’s or Whole Foods. There’s usually oil on top and once you mix it, the peanut butter is drippy and you can drizzle it. Of course, once you get the bottom of the jar, it’s drier and no longer drizzly.

  1. Just a tip, but you should offer directives on a non-vegan alternative for the milk. I for one am very interested in trying your oatmeal bars, but nowhere am I finding which percentage of milk I should use, or even if I should use more or less of it than almond milk. Any tips would be really appreciated.

    1. Hi Cynthia. Great question… any percentage of milk will work, but 2% is probably the most similar to the consistency of almond milk.

  2. This looks good! I am thinking adding some strawberries would give it a nice PBJ vibe! Can’t wait to try it!

    Thank you for the recipe! Can’t wait to try! Quick question – can you substitute the maple syrup with honey?

  4. 5 stars
    LOVE this recipe! PB and banana are one of my favorite combos and this didn’t disappoint.
    I didn’t have flaxseed so I just left it out and it was delicious. This will be a regular for me.

    1. Ahhh that makes me so happy to hear, Lori. So glad the recipe turned out for you and that you loved it. Thanks for taking the time to leave a comment and star rating. It’s super helpful to other readers. 🙂

  5. Am I assuming correctly that the flaxseed included in this recipe for pb banana baked oatmeal should be ground?

    Looks delicious, I’m excited to try it out. Going to go ahead and grind the flaxseed for this try as it will definitely make a consistency difference.

  6. Me: delicious food! what’s the best way to try all these brilliant recipes. Thinking… Solution: send Britanny marriage proposal.

    Waiting… lol joking. Thanks for the recipes.

    I’ve been loving these big baked oatmeal recipes. This one is no exception. I usually double the batch and have been adding 2 eggs or so for a little extra protein. It serves myself, my hubs, and toddler for breakfast most of the week and keeps well, reheats beautifully, and we can all add the toppings we like (syrup for the kiddo every recipe!) I’m thinking of making your chia jam To go with this for PB&J baked oatmeal.

    1. Ohhh yes, my chia jam recipe would be amazing with this baked oatmeal!! I’m so glad you loved this recipe, Sonya. Thanks for coming back to leave a comment and star rating. It means the world to me. <3

    This is delicious! I made it this weekend and my family and I ate it all within a day. Will make some more this week! 🙂

    1. Woo-hoo! I’m so glad this baked oatmeal was a hit with your family! Thanks so much for coming back to leave a comment and star rating. It means the world to me. 🙂

  9. Please can we have the recipes in grams and ml – cup sizes are not universal and it’s a waste of ingredients guessing and getting it wrong

    1. Hi Helen. I don’t currently provide grams or ml for my recipes, but I will certainly make note of the request. In the meantime, there are online converters that you can use. Sorry for any inconvenience.

    This is so amazing! I don’t actually like oatmeal in any form (stove top, microwave, overnight) but I love this. My kids love any kind of oatmeal and this was no exception!

    1. Ahh that makes me so happy to hear, Selena!! I’m so glad you and your kids love this baked oatmeal. Thanks for coming back to leave a comment + star rating, I so appreciate it. <3

    1. Hey Lynzi – Did you add any extra liquid to the recipe or change anything about the recipe? And did you let it set prior to eating it? It could have just taken longer due to your oven. Cook times definitely vary based on the heat of your oven. I’m glad you enjoyed it though!!

  11. My friends loved this recipe, I want to do it again, but can I leave out the peanut butter? or do I need to substitute with something else? Thank you!

  12. 5 stars
    Yum! I made this today with an egg in place of the flax, plus added 1/4cup chia seeds. I cut it into pieces, wrapped in foil and sick in the freezer for easy breakfasts. Can’t wait to really dig in!

    1. Yay!! So glad you enjoyed this recipe, Laura!! Thanks for trying it and for coming back to leave a comment and star rating. I really appreciate it. <3

    I made these for the first time this afternoon and made a few minor changes because of what I had in my pantry. I used only two bananas because that’s all I had, snd used peanut butter powder mixed with water for the drizzle on the top. Saved a ton of calories! Also in place of the cinnamon I used Bakers Chai powder (available at the Savory Spice Shop on line ) and they came out delicious! I snuck a taste and can’t wait for breakfast. I made them all summer with blueberries and peaches and froze them and reheated whenever I wanted one!!
    Delicious and so simple and versatile!

    1. So glad you loved this recipe, Trudy! Thanks for making it and for coming back to leave a comment + star rating. I so appreciate it. <3

  18. I have made a few of your baked oatmeals & they’re yummy BUT there are a # I can’t make (including this one) as they’re way too high in FODMAPS. (So no peaches, no apples & only minimal bananas.) Would it be possible to make this w/ only 1 banana thus lowering the fructose load that my tummy can’t handle? Also, my son is allergic to peanut butter, could this be made with another nut butter? Thanks.

    1. Hey Julie – Yes, you can use almond butter instead of pb and as far as the banana goes, I would swap the second one with applesauce if you can have that.

  19. 4 stars
    So easy to make as I typically always have all ingredients on hand. Super filling and lots of yummy flavors! Just wish my 7 year old liked it!

    This tastes really good. I might try a slightly larger dish next time because this came out really tall and didn’t quite bake through. I baked it for 35 minutes and then put it back in the warm oven for another five minutes. I also added cocoa chips. I didn’t have the flax seed. I’m curious to see if the texture changes after fully cooling.

    1. Hey Melissa – I’m glad you enjoyed the taste of this recipe! The chocolate chips probably added a bit more liquid once melted so the baked oatmeal probably just needed some extra time to cook. Let me know how this ended up turning out for you!!

  21. 5 stars
    Made this this morning, and I only slightly fiddled, adding a handful of chocolate chips. Delicious and kid approved! #EBFrecipeclub

    1. Woo!! So glad you loved this recipe, Carla. Thanks for making it and for coming back to leave a review. I so appreciate it!

  22. 5 stars
    Perfect for a snow day! Warm, filling and leftovers! My husband who is not nearly on the oatmeal train as I am loved it as well. That’s a win in my book. I plan to reheat this with a little drizzle of nut milk over top. 10/10 recommend!

    1. Woo!! That makes me so happy to hear, Amanda. I’m glad it was a hit! Thanks for making it and for coming back to leave a review. I so appreciate it!

  23. Hi! Want to try this recipe but slightly confused about the bananas. The 2 bananas that go into the mixture, are we trying to keep them whole (like whole slices) or mash/break them up as we mix it together? Thanks!

      1. Thank you! That’s what i did but the mixture seemed too wet after baking. Once I left it overnight, it was perfect. My 12 mth old gobbled it up for breakfast this morning! Do you have any tips for freezing? Would love to keep a freezer stash, if it holds up well to freezing.

        1. Yes!! I love freezing baked oatmeal. I normally cut it up into individual portions and freeze them individually versus the whole baked oatmeal together. It makes for easier reheating. 🙂

  24. 5 stars
    I haven’t tried an EBF recipe I didn’t like, but this one is definitely a favorite around here. My five-year-old and two-year-old both beg for it every time I buy bananas and love helping me make it and eat it!

    1. Ahh yay!! That makes me SO happy to hear, Rebekah! So glad this recipe was a hit. Thanks for coming back to leave a review. I so appreciate it!

    1. I love eating it cold too!! So glad you loved this recipe, Samantha. Thanks for the review. I so appreciate it!

  25. 5 stars
    Delicious and so easy to make! It’s like a dessert and a welcomed, warm change to the overnight oats we have so frequently. Baked oatmeal FTW! Thanks for the recipe!

  26. 4 stars
    The only change I made was leave out the sweetener, which made it taste pretty pain except where the banana slices were. I used frozen bananas and I don’t recommend it because they get very mushy. The flavor was a little bland so maybe adding more peanut butter or mashing the bananas into the mixture would be better. The texture is not too porridge-like or too dry, but I like mine firm enough to hold its shape in a bar, so I’ll add less liquid next time.

  27. 5 stars
    YUM! Another amazing baked oatmeal. Banana and peanut butter are my favorite combo and were delicious in this oatmeal! It has a touch of sweetness but was also very savory. Husband loved too!

  28. 5 stars
    This is my favorite of all the EBF baked oatmeals! It’s so comforting, healthy, filling, and feels indulgent! So perfect on a cold morning too:)

    1. So glad you’re loving this recipe, Jamie!! Thanks for coming back to leave a review. I so appreciate it!

  29. 5 stars
    Love this recipe, but for a dessert as opposed to breakfast, by halving the serving size. It’s easy, one of those that you’ve got all the ingredients and a great way to use bananas. We love it warmed up with real cream whipped topping and chocolate drizzled on it.

  30. I loved this so much but added turmeric and chia the second time I made it for a more prominent earthy tone to it. So so so good.

  31. 5 stars
    I made the peanut butter banana fir my family this wkend…. it was a hit! I used cashew butter as a topper. It’s a very simple recipe, easy to make with kids and not time consuming
    Healthy breakfast option ❤️

    Oh my goodness !! I love this recipe and throwing in a few chocolate chips is a bonus. Great cold breakfast on hot summer mornings.

    Love this just like I love most of your recipes. My one year old devours this for breakfast!
    (I usually reduce the amount of maple syrup when making it for her but that’s the only change I make)

    1. Woo!! So pumped this baked oatmeal has been a success, Sarah! Thanks so much for the review and star rating. It means so much to me!

    1. Happy to hear you enjoyed this oatmeal, Amber! Love the addition of blueberries as well. Thanks for the review! I so appreciate it :).

    Husband loves this. I’m not a big PB girl, myself. By request, he asked me to double the PB. Now I’ve been making this for him and the berry erosion of baked oatmeal for myself. The only thing I do differently is add 4 eggs (because we love them) and I think my non-measured cinnamon would be like 1T worth. I’ve made these like 4 weeks in a row. Such easy breakfasts. Thanks!

    1. YUM! I am so glad you and your husband are loving these baked oatmeals, Amy. Thank you so much for coming back and sharing your review & star rating, I really appreciate it! p.s I totally knew what you meant lol!

    Just love this recipe, thank you. I make it every other week but mash my bananas as they’re frozen. It seems to work well though!

    1. Amazing! I am so glad to hear that you are loving this recipe, Jane. Thank you for your review & star rating, it means so much to me!
