These Banana Peanut Butter Oatmeal Bars are just what you need for a healthy and delicious breakfast, snack or treat. These bars are easy to make and packed with nourishing ingredients like oats, bananas and peanut butter.

There’s nothing I love more than a snack made with oats, like these Oatmeal Banana Cookies or these Oat Flour Banana Muffins. Oats are so versatile and packed with fiber which leave you feeling full and satisfied.
And these Peanut Butter Banana Oatmeal Bars are no exception! They can be enjoyed as a healthy breakfast, snack or even dessert. This recipe only takes 10 minutes to prepare and 20 minutes to bake and is vegan and gluten-free. (Just make sure to use gluten-free certified oats!)
When I shared this recipe to the Choosing Chia Instagram it went viral with over 15 million views and 300,000 people saving the recipe to make it later. It’s a tried and true recipe that has quickly become a readers favourite in the Choosing Chia community. Enjoy these bars on their own or try them with a green protein smoothie on the side.
Recipe Highlights
- Healthy choice: These bars are gluten-free, vegan and are healthy enough to enjoy for breakfast. Also make sure to try these cookie baked oats for another healthy breakfast you’ll love!
- Easy to Make: With simple ingredients and straightforward steps, these bars are a breeze to whip up!
- Versatile: Have them for breakfast, a midday snack or a sweet treat with a cup of homemade chai latte.
- Nutrient-rich: These bars have fibre, protein and whole grains to keep you feeling satisfied.
Key Ingredients And Substitutions

- Bananas: The more ripe the bananas, the sweeter the bars will be. I recommend using overripe bananas in this recipe. If you don’t like bananas you can substitute with applesauce. Have extra bananas? Turn them into some Vegan Gluten-Free Banana Bread or some Almond Flour Banana Muffins.
- Peanut Butter: You can use any type of nut or seed butter if you want to keep the recipe nut-free. If you love peanut butter also try these Chocolate Peanut Butter Protein Bars and Peanut Butter Chia Pudding!
- Honey: These bars can be sweetened with honey, maple syrup or agave syrup.
- Rolled Oats: You can use rolled oats or quick oats for this recipe. Rolled oats will give you a chewier texture. (I personally recommend rolled oats for these bars.)

How To Make Banana Oatmeal Bars

Step 1: Mash the overripe banana in a mixing bowl.

Step 2: add the peanut butter, maple syrup and vanilla extract and mix together.

Step 3: In a separate bowl mix the oats, baking powder and cinnamon.

Step 4: Mix the wet and dry ingredients together to combine.

Step 5: Add chocolate chips and mix.

Step 6: Add the mixture to an 8×8 inch pan lined with parchment paper

Step 7: Bake at 350 degrees for 20-25 minutes.

Step 8: Let cool completely, then slice into bars.
Recipe Variations
- Double Chocolate: add 1/4 cup of cocoa powder to these bars to make them extra chocolatey.
- Add some crunch: Add chopped walnuts or almonds for an extra crunch and a boost of omega-3s.
- Berry Oatmeal Bars: Fold in some fresh raspberries or blueberries.
- Add More Protein: Mix in a scoop of your favourite protein powder like I add to these Protein Banana Muffins for an added protein kick.
How To Store
Store these oatmeal bars can be stored in an airtight container at room temperature for up to 4 days, or refrigerated to extend their freshness to a week.
To freeze, wrap the bars individually in plastic wrap and place them in a freezer bag. They can be frozen for up to 3 months. To defrost let the bars thaw on the countertop, and reheat in the microwave for 20-30 seconds.
Expert Tips
- Use overripe bananas: these will give the bars the best natural sweetness and moisture.
- Quality peanut butter: Opt for natural, unsweetened peanut butter for a healthier option and better texture. Use leftover peanut butter in a batch of Peanut Butter Chia Pudding.
- Line your pan: Use parchment paper to line your pan for easy removal and clean-up.
- Don’t overmix: Mix the ingredients until just combined to avoid dense bars.
- Cool completely: Allow the bars to cool completely in the pan for easier slicing and better texture. If you try to remove them too quickly they can fall apart.
