A Little Story From Our Life
Over the last year, Jason and I have been working nonstop on The Manor, our dream renovation project about an hour from where we currently live. Between trips back and forth and all the projects we have been tackling, meal planning has sometimes felt impossible.
When you are on the go that much, it is tempting to eat out constantly but we noticed it was taking a toll on our health and our budget. That is why these bars have been such a lifesaver for us. They are easy to prep, wholesome, and totally grab-and-go, so we can refuel during long days of sanding, painting, or hammering without missing a beat.
These little bars have become our project-day snack of choice, and I love that they are something nourishing I can feel good about.
Ingredients
- 1 1/2 cups mashed bananas (about 3 ripe bananas)
- 1/2 cup nut butter of choice (peanut, almond, or cashew work beautifully)
- 2 cups rolled oats
- 1 tsp cinnamon
- 1 tsp vanilla extract
- 3 tbsp maple syrup
- 1 cup dark chocolate chips
- 1/2 tsp salt
Instructions
- Preheat your oven to 350°F (175°C) and line an 8×8-inch baking pan with parchment paper.
- In a large bowl, mash the bananas until smooth.
- Add the nut butter, maple syrup, vanilla, and salt and stir until everything is well combined.
- Mix in the rolled oats and cinnamon, folding until fully incorporated.
- Fold in the dark chocolate chips, leaving a few for topping if you like a pretty finish. I also added chia seeds for extra nutritional benefits.
- Press the mixture evenly into your prepared pan.
- Bake for 25 to 30 minutes or until the edges are lightly golden.
- Cool completely before slicing into bars. Store in an airtight container for up to 5 days or freeze for longer storage.

Frequently Asked Questions
Can I use quick oats instead of rolled oats?
Yes, you can use quick oats, but the texture will be softer and less chewy. Rolled oats give the bars more structure and a heartier bite, which works best for this recipe.
Can I make these peanut butter banana oat bars gluten-free?
Yes. Just make sure you use certified gluten-free rolled oats. All other ingredients in this recipe are naturally gluten-free.
What can I use instead of peanut butter?
You can substitute almond butter or cashew butter with great results. Sunflower seed butter also works if you need a nut-free option, though it will slightly change the flavor.
How ripe should the bananas be?
The bananas should be very ripe with lots of brown spots. The riper they are, the sweeter and more flavorful your bars will be, and the better they will mash into the batter.
Can I reduce the maple syrup or leave it out?
Yes, you can reduce or omit the maple syrup if your bananas are very ripe. The bars will still be naturally sweet from the bananas and chocolate chips, but the texture may be slightly less moist.
Why are my oat bars too soft or falling apart?
This usually happens if the bananas are too large or the bars were underbaked. Make sure to measure mashed bananas (about 1 1/2 cups) and allow the bars to cool completely before cutting so they firm up properly.
Can I make these peanut butter banana oat bars dairy-free?
Yes. Just use dairy-free dark chocolate chips and ensure your nut butter is dairy-free, which most are by default.
How do I store banana oat bars?
Store them in an airtight container at room temperature for 2–3 days, or refrigerate for up to 1 week. They can also be frozen for up to 3 months.
Can I freeze these bars?
Yes, these bars freeze very well. Wrap them individually or store in a freezer-safe container. Let them thaw at room temperature or warm slightly before eating.
Can I add mix-ins to this recipe?
Absolutely. You can add chopped nuts, shredded coconut, chia seeds, or dried fruit. Just avoid adding too much extra moisture so the bars hold their structure.
