5-Ingredient Chewy Banana Granola Bars
These banana granola bars are the answer when you need a quick homemade snack that actually holds together. They come together with just five main ingredients and bake up chewy, not crunchy, so they are perfect for lunchboxes or an afternoon pick-me-up.
The ripe bananas sweeten the bars naturally and keep them moist without any oil. Everything gets pressed into a pan, baked until the edges turn golden, and sliced into sturdy squares you can grab on the way out the door.
Why This One Stays in the Rotation
The bananas do double duty here: they sweeten the bars and keep them tender without a drop of added oil. I reach for this version whenever the counter has a couple of spotty bananas that nobody is eating.
They hold together without turning into a brick, and the taste is like a cross between banana bread and a chewy granola bar. You can swap the chocolate chips for nuts or dried fruit, but the peanut butter and honey tie it all into a bar that actually tastes like a treat.
Ingredients
- 2 large very ripe bananas: the spottier, the sweeter. You need about 1 cup mashed.
- 2 cups old-fashioned rolled oats: not quick oats, for the best chewy texture.
- ½ cup creamy peanut butter: use a well-stirred natural peanut butter or a no-stir variety.
- ⅓ cup honey or maple syrup: maple syrup keeps the bars vegan.
- 1 teaspoon vanilla extract
- ½ teaspoon ground cinnamon: optional, but gives a warm note.
- ¼ teaspoon fine salt: if your peanut butter is salted, you can skip it.
- ½ cup mini chocolate chips: or chopped dark chocolate. Omit or swap for nuts, seeds, or dried fruit.
Variations / Substitutions
- Swap the peanut butter: almond butter or sunflower seed butter both work; the taste will shift but the texture stays the same.
- Make them vegan: use maple syrup instead of honey and dairy-free chocolate chips.
- Change the add-ins: chopped toasted walnuts, pecans, raisins, or dried cranberries instead of chocolate chips. Keep the total to about ½ cup.
- Add a little crunch: stir in 2 tablespoons of chia seeds or hemp hearts with the oats.

How to Make 5-Ingredient Chewy Banana Granola Bars
Step 1: Mash the Bananas
Peel 2 large ripe bananas and drop them into a large mixing bowl. Mash with a fork until mostly smooth with only a few small lumps left. A few tiny bits are fine, they will melt into the bars as they bake.
You want a very smooth, almost liquid mash so it coats the oats evenly. If your bananas are not fully spotty yet, the bars will still work but will be less sweet.
Step 2: Mix the Wet Ingredients and Oats
Add ½ cup creamy peanut butter, ⅓ cup honey, 1 teaspoon vanilla, ½ teaspoon cinnamon, and ¼ teaspoon salt to the bowl. Stir everything together until it looks like a uniform glossy paste. Then pour in the 2 cups old-fashioned rolled oats and fold until every oat is wet and no dry pockets remain.
At this point the mixture will be thick and a little sticky. It should hold its shape when you press it against the side of the bowl. If it seems too dry, add an extra tablespoon of peanut butter or honey.
Step 3: Fold in the Chocolate Chips
Scrape down the bowl, then pour in the ½ cup mini chocolate chips. Fold gently until the chips are scattered throughout. The dough will start to smell like banana-oatmeal cookie dough at this stage.
If the mixture got a little warm from your hands or the weather and the chips start to melt, don’t worry. It’s fine if a few streaks appear; that just means little pockets of chocolate in the baked bars.
Step 4: Press into the Pan and Bake
Preheat the oven to 350°F (180°C). Line an 8-inch square baking pan with parchment paper, leaving a little overhang on two sides. Scrape the oat mixture into the pan and press it firmly into an even layer. Use the back of a spatula or slightly wet hands, really compact it so the bars won’t crumble later.
Slide the pan onto the middle rack and bake for 18 to 22 minutes. The edges will turn a light golden brown and the top will look set and just starting to dry out. The center might still feel a little soft when you press it, but it firms up as it cools.
Step 5: Cool and Slice the Bars
Set the pan on a wire rack and let the bars cool completely, about 1 hour. This cooling time is non-negotiable; cutting too soon will leave you with a crumbly mess. Once fully cool, lift the slab out using the parchment, set it on a cutting board, and slice into 12 bars with a sharp knife.
The bars will be dense and chewy, with little pockets of melted chocolate. Serve right away or pack into a container.
Tips for Bar That Don’t Fall Apart
- Use truly ripe bananas.: Yellow bananas with a few brown spots are fine, but mostly yellow ones won’t add enough moisture or sweetness.
- Press, press, press.: The tighter you pack the mixture into the pan, the better the bars hold together after baking. Press firmly with the back of a spatula, the bottom of a measuring cup, or damp fingers.
- Let them cool all the way.: Warm bars are fragile. Give them the full hour so the peanut butter and honey set up and the bars slice cleanly.
- Store them in the fridge for extra chew.: Chilling makes the bars even firmer and chewier, like a dense oat snack cake.
Bake times by pan size:
| Pan size | Bake time | Note |
|---|---|---|
| 8-inch square | 18–22 minutes | Bars will be about ¾ inch thick. |
| 9×13-inch pan | 12–15 minutes | Bars will be thinner, keep an eye on the edges. |
Storing Leftover Bars
- Refrigerate: Layer the bars between sheets of parchment in an airtight container. They keep well for up to a week, and the texture gets even chewier. Let them come to room temperature for a few minutes if you prefer a softer bite.
- Freeze: Wrap each bar individually in plastic wrap or parchment, then tuck them into a zip-top bag. Freeze for up to 3 months. Thaw overnight in the fridge or on the counter for an hour.
- Reheating: Not needed, but 10 seconds in the microwave softens the chocolate and makes them taste freshly baked.
Frequently Asked Questions
Can I use quick oats?
Yes, but the texture will be softer and the bars will be less chewy. Old-fashioned rolled oats give the best sturdy, chewy bite, so I stick with those.
Why did my bars crumble when I sliced them?
Two likely reasons: the mixture was not pressed firmly enough into the pan, or the bars were still warm when you cut them. Press the mixture hard and wait until they are fully cool, about an hour, before slicing.
Do I need to add any extra sugar?
No, the ripe bananas and honey already make these bars plenty sweet. If your bananas are not very ripe, the bars will taste less sweet; you can stir in 2 tablespoons of brown sugar or coconut sugar if you like a sweeter snack.
