What You’ll Need
- Banana: You’ll need a medium-sized ripe, lightly spotted banana. You can substitute applesauce or pumpkin puree but the bars will be less sweet.
- Peanut Butter: Use natural peanut butter. You can substitute almond butter to make them peanut free or sunflower seed butter to make them nut-free.
- Maple Syrup: Use pure maple syrup or substitute agave syrup.
- Vanilla: Artificial or pure vanilla extract is fine.
- Oats: Use old-fashioned oats (rolled oats).
- Oat Flour: You can use store-bought oat flour or homemade oat flour. If you’re making your own oat flour, just make sure it’s finely blended.
- Baking Soda: Watch you use baking soda, not baking powder.
- Cinnamon: Technically optional but always a nice addition!
- Chocolate Chips: You can use any dairy-free chocolate chips or dark chocolate chips such as Enjoy Life or Camino. Chopped dark chocolate would also work.
How to Make (with Photos)
Step 1: Prepare to Bake
Prepare to bake by preheating the oven to 350 F and either spraying an 8×8-inch pan with cooking spray or lining it with parchment paper.
I’d suggest parchment so the bars are easy to lift out of the pan and slice.
Step 2: Mix Wet Ingredients
In a large bowl, mash the banana into a paste with a fork then add the peanut butter, maple syrup and vanilla. Mix until completely smooth.
Step 3: Add Dry Ingredients
Add the oats, oat flour, baking soda, salt and cinnamon and mix to combine, then stir in the chocolate chips.
Step 4: Bake the Bars
Spread the mixture into the prepared baking pan, spreading evenly with a spatula, wooden spoon or even your fingers. Sprinkle extra chocolate chips on top – optional but recommended!
Don’t completely smooth the top out, just make sure it’s evenly spread around the pan. Leaving some texture on the surface will help them crisp up on top.
Bake your bars at 350 F for 17-18 minutes or until a toothpick inserted into the middle comes out clean.
You don’t necessarily have to check with a toothpick. The bars should be fairly firm and crisp on top and golden brown around the edges when they’re done.
Step 5: Cool and Slice
Once they come out of the oven, let them cool for at least 30 minutes in the pan before slicing. This helps ensure the bars will hold together well.
Don’t skip cooling or they may be too gooey and fall apart. I’d suggest at least 30 minutes of cooling if not letting them cool completely.
Frequently Asked Questions
No. You can make these with almond butter, cashew butter, tahini or sunflower seed butter.
Use tahini or sunflower seed butter if you need them to be nut-free.
This recipe is gluten-free as written as long as you use gluten-free certified oats and oat flour.
These bars are vegan (egg-free and dairy-free) as long as you use dairy-free chocolate chips or dark chocolate.
They definitely have a slight banana flavour to them. The most pronounced flavour is peanut butter, followed by banana.
If you don’t like banana, this may not be the recipe for you. You might like these no-bake oatmeal bars, chocolate oat bars, no-bake oatmeal raisin bars or peanut butter bars instead.
The top and edges of the bars are crispy and the inside is soft, gooey and so delicious. The perfect combo!
How to Store

- Fridge: Store the bars in an airtight container in the fridge for up to 1 week.
- Freezer: Wrap the bars tightly and freeze in the pan or slice and transfer to a freezer bag or airtight container and store for up to 3 months.
