Banana Peanut Butter Oat Bars are made with just 7 ingredients for a healthy, simple snack. Rich in fiber and protein, these homemade granola bars will keep you full and fueled.
Why You’ll Love These Homemade Granola 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 more sustenance than just a piece of fruit.
- 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.)
Banana Peanut Butter Oat Bar 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 up of pumpkin puree instead.
- Old fashioned 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: Feel free to use almond butter or cashew butter instead. Or, alternatively, if you have a nut allergy, use sunflower seed butter.
- 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 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. Additionally, chopped walnuts are always a win for even more heart-healthy, satiating fats.
Step-by-Step Instructions:
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
Add the two bananas to a large, wide-rimmed bowl. Use a fork to throughly mash each banana until they look pureed.
Step 2: Stir in the Peanut Butter, Maple Syrup, and Coconut Oil
Next, stir in the peanut butter, maple syrup, coconut oil, and vanilla extract. Mix the ingredients until well-combined.
Step 3: Stir in the Oats and Protein
Stir in the oats, protein powder/collagen (if using), and salt. Next, add the chocolate chips and walnuts, if using, and stir to combine. Transfer the mixture to an 8×8 baking pan lined with parchment paper, and top with some additional chocolate chips.
Step 4: Bake the Oat Bars
Bake the bars at 350 degrees F for 22 to 24 minutes, or until the mixture appears to be set. Next, remove them from the oven and let cool completely, which may take about 1 hour. Once cool, slice into 10 bars and enjoy!
FAQs About This Recipe:
Can I Make These Oat Bars Vegan?
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 raisins (oatmeal raisin cookie bars FTW!), walnuts, or macadamia nuts.
How to Store Oat Bars:
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.
Can you Freeze Oat Bars?
Yes, you can freeze this banana peanut butter oat 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.

The whole family loves these. Easy quick tasty breakfast or snack!
My husband has been asking me to make them again, so I just made two batches. First batch has dried tart cherries, chopped walnuts, cacao nibs, 2 scoops vanilla protein powder. no syrup or honey. I scattered unsweetened grated coconut over the top prior to baking. Second batch has chopped macadamia nuts, grated coconut, and crunchy peanut butter. Great basic recipe, super easy to put together in a heavy mixer. I prefer the flavor of less ripe bananas, and no syrup or honey. My version more than doubled protein too.
Sounds delish! Thanks for sharing your substitutions!
I have made these multiple times and my kids love them! Thanks for the easy healthy recipe.
Hi Sandra – I’m so glad you enjoyed this one! Thank you for taking the time to leave a review!
Love these. Making them now for the 3rd time in about a month! Kids love them . Ask for me to make every week. I’m getting creative with adding cranberries and Coconut. I don’t add the chocolate. I too prefer honey to syrup. These are a great healthy and filling snack option. This is a keeper for sure!
Woohoo! I’m so glad you enjoyed these, Ingrid. Thank you for taking the time to leave a review!
Can I use butter instead
Hi Derrick – melted butter should work fine!
Okay! Seriously….I’m kind of a picky jerk….but these are remarkable and incredibly delicious! I followed the recipe with two exceptions…. I only had half the amount of maple syrup needed so I substituted honey for the rest and I used my vanilla protein powder because that’s what I had on hand. They come together quickly and easily. Thank you for this recipe!!!! It’s definitely going to be part of my regular rotation! 🙏🏼🥰
Hi Deborah – I’m so thrilled you enjoyed these bars!! Thanks for leaving your substitutions for other readers to see. And thank you SO much for leaving such a fab review!
These look awesome but I do not have any protein powder, will they be okay without or do you recommend using oat flour or almond flour instead? Or any other substitute? Thanks so much!
Hi Kate—you can use 3-4 Tbsp. oat flour or almond flour instead!
This a great alternative to banana bread for using up old bananas. Very tasty!
I’m so glad you enjoyed them, Angie! Thank you for taking the time to leave a review!
If I don’t have coconut oil on hand can I sub vegetable oil or olive oil instead?
Hi Hannah, yes either of those will work fine!
I made these last night and wow! They are so so so good. My mom decided to take one work and she said she loved it so much that she ate it too quickly and then was sad that there wasn’t any left. They’re soft, have a nice sweetness, and the perfect balance of banana, peanut butter, and chocolate. I used honey instead of maple syrup simply because I prefer the flavor but seriously, this was one of the best things I’ve had in awhile. Thanks for the recipe!
Made a batch last night, brought them to work this morning – the boys devoured them all. We had a wonderful workout after thanks to the energy – Truly a hit , thanks!
Yayy, I’m so thrilled to hear that, Christine!! Thanks so much for coming back and sharing! Cheers.
These sound super delicious. Thanks for sharing this recipe with us.
