Why You’ll Love These Banana Peanut Butter Bars:
Wholesome, nutritious and easily adaptable using your favorite mix-ins. These bars my go-to for healthy, homemade snacks.
Here are all the times these bars come in clutch:
- When that 3 o’clock crash hits and you just need a little something to tide you over.
- For breakfast-on-the-go when you need something fueling (see also my Banana Bread Bars.
- For dessert when you’re craving something sweet but trying to avoid a sugar crash.
Basically, any time the snack craving strikes, these bars will have your back.
They’re chewy, nutty and subtly sweet. (Think baked oatmeal mixed with a peanut butter chocolate chip cookie.)

Recipe Ingredients:
Many of the ingredients in these bars can be modified based on your preferences/allergies. Here’s what you need:
- Bananas: Two ripe bananas add natural sweetness and moisture to these bars. If you’re not a fan of banana, use 2/3 cup of pumpkin puree instead.
- Rolled oats: Use a certified gluten-free brand, such as Bob’s Red Mill, if you need to make these bars 100% gluten free.
- Peanut butter: Look for a natural, drippy peanut butter that only includes peanuts and salt on the ingredient list. Alternatively, you can almond butter or cashew butter instead.
- Maple syrup: Any kind of liquid sweetener will do the job, such as honey, agave, or brown rice syrup. However I love the richness of maple syrup, especially paired with nut butter.
- Chocolate chips: Totally optional, however a little bit of chocolate makes these bars feel indulgent. Alternatively, feel free to use dried fruit or chopped nuts.
- Coconut oil: Coconut oil adds moisture and chewy goodness to these oat bars.
I also like adding a couple scoops of collagen for a protein boost. You can choose to leave this out, or add ~20g of your go-to protein powder.
See the recipe card below for the complete list of ingredients and quantities.
Substitutions/Additions:
- Add nuts: Either in addition to or in place of the chocolate chips, walnuts are a wonderful addition that slip in extra heart-healthy fats.
- Make Vegan: These banana peanut butter bars are naturally vegan as long as you don’t add collagen powder. You can, however, add a scoop of your favorite plant-based protein powder.
- Make Nut-Free: If you have a nut allergy, sunflower seed butter will work in place of the peanut butter.
- Add Fruit: I love adding dried cherries to these bars! Their sweet-tart flavor complements the chocolate beautifully.
The Directions:
These homemade granola bars only take 10 minutes to make, and ~20 minutes to bake. Here’s how to make them:
Step 1: Mash the banana in a large bowl until pureed.
Step 2: Add wet ingredients, including peanut butter, maple syrup, coconut oil, and vanilla extract. Mix the ingredients until well-combined.
Step 3: Stir in dry ingredients, including oats, protein powder/collagen (if using), and salt. Lastly, Next, fold in the chocolate chips and walnuts (if using) and stir to combine.
Step 4: Pour mixture into an 8×8 baking pan and top with some additional chocolate chips. Bake at 350 degrees F for 27-32 minutes, until set.
Let cool completely before slicing into 12 bars and enjoying!
Recipe FAQs
These oat bars are naturally vegan without the chocolate chips. In lieu, you can use cacao nibs, dried fruit, or extra chopped nuts. I personally love dried cherries, walnuts, or pecans.
Once the bars completely cool, slice them into pieces and place in an airtight Tupperware container. You can store the bars in the refrigerator or at room temperature, if you prefer. I personally love them both ways, however they do tend to dry out more in the fridge.
Either way, they will last 4 to 5 days if properly stored.
Yes, you can freeze these banana peanut butter bars. Here’s how:
First, let the oat bars cool to room temperature.
Next, slice them into individual squares, and wrap each square in plastic wrap.
Place the bars in an airtight container and store in the freezer for up to 3 months.
To reheat: remove the plastic wrap and warm on a microwave-safe plate for 30-60 seconds.

Notes
Nutrition
I calculate these values by hand to ensure accuracy, however expect up to a 10% variable depending on food brands.
Can I substitute the collagen protein whit Greek yogurt or anything else?
Because I don’t have powder protein
I haven’t tried using yogurt… I would probably just omit the collagen/protein powder entirely.
These are so delicious and filling! I’ve made these now several times. Would swapping unsweetened applesauce for the maple syrup work?
I haven’t tried so I can’t say for sure… I’d maybe use half applesauce and half maple syrup to start.
These are THE BEST!! A friend shared the recipe towards the beginning of the year and I’ve made them about every 2 weeks since then. They are just so good & the latest batch I have in the oven I’m taking with me to snack on for a big convention I’m headed to.
I’ve been meaning to make these for awhile and your story yesterday reminded me to do so! They are great!! A perfect sweet but healthy treat – and a wonderful way to use up two overly ripe bananas! Thank you 🙂
As someone that craves a little bite of something sweet daily, these really hit the spot! I have made several times now and shared with friends/family who also loved them!
These are a staple in our home!! My two kids and husband normally polish off the batch within a day or two!
YAY! So thrilled to hear that, Campbell! Thank you for leaving a review!
Love how simple and tasty these are. I make them every month in my house.
Love these
These are the best protein bars I’ve made so far! My teenagers love them. They have almost the same ingredients as our usual raw ones but taste so much better baked! I baked these in an air fryer lined with baking paper & they were perfect! 5 stars!
