This peanut butter baked oatmeal is our family’s all-time favorite breakfast, and we aren’t just saying that🥜 We love making baked oatmeal at the cabin for a large group of people because it’s such an easy breakfast for the masses. People devour it for breakfast, and if there is any left, it’s a sweet treat throughout the day.
why we love this pb banana baked oatmeal recipe
This particular oatmeal bake recipe is wonderful for so many reasons:
- It’s 100% gluten-free! It’s made with rolled oats and ground oat flour. Great for those that can’t gluten or that are allergic.
- Oatmeal bakes are just an all-around winning breakfast. They taste like dessert, but are actually good for you!
- This peanut butter banana oatmeal baked recipe combines all of my favorite things…peanut butter, banana, and oats. LOLZ.
Ingredients Needed for Peanut Butter Banana Baked Oatmeal
- Banana: We used ripe bananas for this recipe as they’re sweeter than less ripe bananas. They add natural sweetness, moisture, and a wonderful banana flavor to the oatmeal. We mash them up to bind everything together and create a delicious base for the other ingredients.
- Eggs: They act as a binder, helping the oatmeal hold its shape and giving it a nice fluffiness once baked.
- All-natural peanut butter: This creamy goodness is what makes this recipe peanut butter banana! It adds protein, healthy fats, and, of course, that classic peanut butter taste we all love.
- Vanilla: A splash of vanilla extract is like a magic touch. It enhances all the other flavors in the recipe.
- Pure maple syrup: This natural sweetener adds a touch of sweetness without being overly processed.
- Unsweetened almond milk: This is the liquid base that helps cook the oats and keeps everything nice and moist. You can use regular milk too if you’re not avoiding dairy.
- Rolled oats: These are the foundation of the oatmeal! They provide a satisfyingly chewy texture and keep you feeling full for longer. We like to use rolled oats because they offer a nice bite compared to quick oats, which can get mushy.
- Oat flour: This is a fantastic option for a denser and more cake-like oatmeal texture.
You can’t go wrong with that ingredient list, people. Plus, if you’re sick of overnight oats, baked oatmeal is the PERFECT substitute!
Baked Oatmeal Customizations
- Almond Butter or Cashew Butter: If you’re not a fan of peanut butter or have nut allergies, this recipe is easily adaptable! Almond butter or cashew butter creates a delicious twist.
- Chocolate Drizzle: Take your oatmeal to the next level with a decadent chocolate drizzle! Melt some dark chocolate, semi-sweet chocolate, or even white chocolate and drizzle it over the top of the baked oatmeal for a decadent touch.
- Chocolate Chips: Who can resist chocolate chips? Fold in a cup of your favorite chocolate chips (dark, semi-sweet, milk chocolate, or even white chocolate chips) into the batter before baking. They’ll melt into gooey puddles of joy throughout the oatmeal.
- Drizzle of Peanut Butter: Double down on the peanut butter flavor with a drizzle after baking! Warm up some additional peanut butter (or your chosen nut butter) until it’s pourable, then drizzle it over the baked oatmeal for an extra peanut buttery punch.
- Non-dairy Milk: This recipe is naturally friendly for those who are lactose intolerant or vegan. Simply replace the almond milk with your favorite non-dairy milk! Coconut milk adds a subtle tropical flavor, while soy milk offers a more neutral taste.
here’s a tip!
Keep an eye on your oatmeal while it bakes. Once a toothpick inserted in the center comes out with a few moist crumbs, it’s done. Overbaking can dry it out.

FAQ

I was wondering can the oat flour be replaced with almond flour?
Yes!
Shockingly, this is the first time I’ve ever put peanut butter in an oatmeal recipe. It was so good! Love an oatmeal that’s healthy but can also easily feed a gaggle of kids in the morning. Thanks for the recipe.
What can replace Oat Flour?
White whole wheat or all-purpose!
Love this recipe!! I’m starting ultimate portion fix, and I’m trying to figure out how this recipe will translate to the colored containers, because I definitely want to keep using this recipe!
It’s so good, right?!
My 1 and 3 year old love this “banana cake”. Question – have you ever made the mix as muffins? If so what cooking time would you recommend? Thanks!
Not this mix specifically, but I make oatmeal cups all the time! 16-18 minutes. Here’s one they might love. V similar –> https://fitfoodiefinds.com/peanut-butter-chocolate-chip-baked-oatmeal-cups/
Thought it tasted like cardboard – shared the recipe with my friends anyway.
It was good, albeit a little dry. I ate my twin afterwards as I was unsatisfied.
Twin??
quoted from above…. “Honestly – my biggest fear in life is that my children are either going to despise peanut butter or worse off, be allergic to it. #thehorror”
I have been a big fan of yours for some time and am constantly sharing your recipes but lady im absolutely disgusted, you have some serious nerve to mock and belittle children with food allergies. wow just wow.
It’s clearly a joke about how much she loves peanut butter, lighten up
lol. She is obviously joking. I have a life threatening peanut allergy, and I can see appreciate the humor in this comment. I make this with almond butter. Still amazing!!
They are simply amazing, Lee. Thanks!
This was my first time making baked oatmeal and it was perfect for my 1 year old! Do you store baked oatmeal in the fridge?
Yes, store it in the fridge!
Love this recipe!! How would this translate I to Ultimate portion fix from Beachbody? I want to keep using this recipe, but I need to figure out how the serving size translates to the colored containers.
