Ingredients You Need
- Rolled Oats – These little nutritional powerhouses are the base of the bars and soak up all the goodness of the other ingredients.

- Sea Salt – Just a pinch of sea salt brings out all the sweet and nutty flavors.
- Ground Cinnamon – Cinnamon adds warmth to the bars, making them extra irresistible.
- Nutmeg – Nutmeg gives the bars a subtle touch of spice.
- Overripe Bananas – Overripe bananas are naturally super sweet and creamy, making your bars moist and flavorful.
- Creamy Peanut Butter – Creamy peanut butter adds the signature nutty flavor and rich texture that defines these delicious bars!
- Vanilla Extract – A splash of vanilla extract brings out all of the flavors and gives them an amazing aroma.
- Pure Maple Syrup – Pure maple syrup adds natural sweetness and a hint of maple goodness that we absolutely love!
- Large Egg – A lightly beaten egg helps to bind everything together, ensuring your bars hold up beautifully.
- Whole Milk – Whole milk adds creaminess and makes the bars super moist.
Topping:
- Creamy Peanut Butter – While it’s optional, we love drizzling even more peanut butter over the top.
- Chocolate Chips – Chocolate chips add little pockets of melty, chocolatey bliss!
How to Make Peanut Butter Banana Baked Oatmeal Bars
- Mix Together Wet Ingredients. Fold together the mashed bananas and peanut butter in a large bowl before adding the vanilla, syrup, and egg. Once combined, pour in the milk and stir together.
- Combine the Dry and Wet Ingredients. Pour the oats, baking powder, sea salt, and cinnamon into the banana and peanut butter mixture and mix together until completely combined.
- Bake the Bars. Transfer the oat mixture to the prepared baking dish that has been greased. Sprinkle chocolate chips on top and place in the oven to bake for the recommended time.
- Top and Serve. After removing the pan from the oven, top with more peanut butter if desired. Allow the bars to cool briefly, then slice. Serve immediately or allow the bars to reach room temperature before storing. The bars can be served cold as well.
Variations
- Berries – Mix in dried berries like blueberries, raspberries, or cranberries for a fruity twist.
- Crunchiness – Add chopped nuts like peanuts, almonds, walnuts, or pecans for an extra crunch.
- Chocolate – Swirl in some melted dark chocolate or cocoa powder for even more rich, chocolatey flavor.
- Coconut – Mix in shredded coconut for a tropical flair that pairs perfectly with peanut butter.
- Protein Boost – Stir in a scoop of your favorite protein powder to make these bars a great post-workout snack.
- Pumpkin Spice – Replace bananas with pumpkin puree and add pumpkin pie spice for a fall favorite.
- Nutella – Swirl in some Nutella with the mashed bananas for a heavenly chocolate-hazelnut combination.

Can you substitute non-dairy milk such as almond or oat for the milk?
Absolutely!

Alia & Radwa
Could you add a scoop of vanilla protein powder to this for added protein or substitute liquid protein instead of the milk?
We haven’t tested it, but it should work! However, you may need to play with ingredient ratios, especially when adding protein powder. We’d love to know how it goes if you do give it a try!

I’ve also had a failed attempt as a few others have mentioned in their reviews. I used rolled oats (as suggested) and followed the recipe precisely. I also gave extra time in the oven, hoping that the oats might better come together. Unfortunately, the oat bars still came out very mushy. I think the recipe has to be altered to add additional oats and reduce the amount of milk.
We’re sorry to hear this but appreciate the feedback, Meri! We hope you continue to enjoy our other recipes.

Just made them and am eating a square right now. Delicious and so easy to make. My modifications:
Cooked 35 minutes total.
Used extra crunchy peanut butter – it’s what I like and have on hand.
Used honey instead of maple syrup, which I don’t care for.
I did drizzle the peanut butter and used dark chocolate chips. I couldn’t wait for it to cool properly because smelled so good, so a little soft but kept its shape and I ate it with a fork. I think when it’s completely cool it will be perfect. Thanks for a great recipe.
Soggy and texture with oaty bits ……not for us.
Used the rolled oats and definitely stuck to the measurements (although always a pain converting from cups to grams or ounces.) Weird texture and too crumbly to cut into bars. Maybe British rolled oats are somehow different to US?

Soo yummy! Maybe could have added more cinnamon or nutmeg for flavor but it came out soft & was a household hit.
Thank you, Jess! You can definitely add more spices to suit your preferences. 😊

The recipe really needs to add some kind of flour so it’s not so mushy/gooey. I split the recipe into 2 pans hoping that would help with the soggy-ness, & even over baked them. It still had a weird goey texture & very messy falling apart
We’re sorry to hear this, Briana! What kind of oats did you use?

These turned out great! Super easy to make, I had everything mixed up before the oven was even preheated. The texture and flavour is great! Will definitely make again!
I used white chocolate chips and added some dried cherries too. Mmmmm!
(Note – the previous reviewer had an issue with it being wet/soupy but mine were fine. I used Rolled Oats per the recipe so maybe their oats was their issue?)
Thank you for your feedback, Frances! We’re so glad you enjoyed the recipe! 😊

Can you substitute Almond milk for the whole milk?
Sure! The flavor just won’t be quite as rich. 😊

Made this yesterday. Easy and yummy recipe. Mine came out kinda soft so unable to cut into bars. But still very good!
It might have just needed to baked a tiny bit longer, but we’re so glad you enjoyed it, Tammy!

Yuck! Followed directions exactly. No flavor, soggy. Drizzled with peanut butter and tried topping with maple syrup but still bad. We are a family of 10 ages 5-60 and no one liked them enough to get past a bite or two. Wasted time and ingredients. And I am an excellent cook so I know it wasn’t something I did wrong.
We’re sorry you didn’t enjoy it, Janis. We will make sure to retest it and do hope you give some of our other recipes a try!

These did NOT turn out. Wet soggy sock texture, no sweetness or flavour other than the chocolate chips.. Even left them in the oven for much longer to see if they would ever not be soggy.. an hour later still no.
Wasted ingredients 🙁
We’re sorry to hear this! What kind of oats did you use?
