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 ⅔ 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 8x8 baking pan and top with some additional chocolate chips. Bake at 350 degrees F for 25-28 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.

Used agave/honey since I didn't have syrup. Also used a 9x13 to make more and to make these thinner and crunchier. I also threw these in the fridge to set overnight. They are such a yummy alternative to store-bought bars!
