🍌What you will need:

📓Notes / substitutions
- Make sure that you are using bananas that are ripe and spotty. As they are the main sweetener in this recipe, you will want them to be super ripe and sweet.
- Frozen bananas can be used in this recipe, but do defrost them first.
- To make it gluten-free, use certified gluten-free oats.
- Both quick oats and rolled oats can be used. Quick oats will yield bars that have less texture.
- Feel free to substitute the peanut butter with other nut butters like almond butter or cashew butter. To make it nut-free, use sunflower seed butter or pumpkin seed butter instead.
- If you like more texture and crunch, add in ½ cup of your favorite nuts ! Be sure to chop them up into smaller pieces.

🍫Optional add-ins
- If you like your oat bars to be extra sweet, add 2 - 4 tablespoons sweetener of choice. Some of my favorite includes maple syrup, coconut sugar and raw sugar.
- Add in ¼ - ½ cups of your favorite chocolate chips to jazz things up.
- Vanilla extract will go really well in this recipe to. I recommend adding about 1 teaspoon.
🔪How to make
Start by preheating oven to 180c / 360f . Line or grease a 8x8 square baking pan.

In a large mixing bowl, mash the bananas until smooth, using a fork or potato masher. It is ok to have a few small chunks here and there.

Next, add in the peanut butter and mix well. Then, stir in the oats and mix again until the oats are well incorporated.

Transfer the mixture to the baking pan. Using the back of a spoon or a spatula, smooth out the mixture so that it is evenly distributed.
Bake it in the oven for 20-25 minutes, or until a toothpick comes out clean and the sides are golden brown.
Remove it from the oven and let it cool down completely before slicing. Optionally, drizzle on more peanut butter before serving !
❔Commonly asked questions
They are dense and chewy, yet super moist on the inside, somewhere between the texture of a baked oatmeal and granola bar. They also hold their shape pretty well, making them the perfect portable snack to have with you on the go.
As the texture is not at all similar to normal cooked oats, I urge anyone who hate oatmeal to give this recipe a try. Who knows, you might like them !
Depending on the climate, you do have to refrigerate them if they are not consumed within 3-4 days. Simply transfer them to a sealed container and pop them into the fridge. They can be kept there for a week.
Yes, these bars are freezable ! To do so, let them cool down completely first. Then, arrange them on a large plate / tray in a single layer. Pop them into the freezer for 1-2 hours, or until they are frozen.
You can now transfer them to any storage containers or zip-top bags without worrying that they will be stuck together ! They can be freeze for up to 3 months.
To heat, let them defrost in the fridge overnight, then heat them in the oven at 180c for 8-10 minutes, or until they are thoroughly warmed. Alternatively, heat frozen bars in the microwave oven for 45-60 seconds.

I made these today. I added dark chocolate chips (a half cup) for a little sweetness. I also used unsweetened, sodium free peanut butter My husband loved them too.

Did you mean 350c? Not 150c?
meesha says
It is 150 Celcius ! But if you are using farenheit, it should be about 300 degrees.
Jerry Koch says
Is it 180 c or 150 c?
meesha says
It is 180c ! 🙂
Shannon says
Look wonderful! Could you substitute maple syrup or date syrup for the granulated sugar?
meesha says
Yes of course ! It works well too.
Lisa says
I don’t see sugar in the recipe? Is it
Called for?
meesha says
It is an optional ingredient, hence I did not include it in the recipe ingredients itself. But if you prefer it to be extra sweet, you probably want to add some kind of sweetener. Do check out the notes at the very bottom of the recipe card 😊
Christine says
Love a healthy grab-n-go breakfast now that school is back in! Thanks for sharing!

Bland as all get-out. About as tasty as tofu and peat moss.
Needs a sweetner like maple syrup or honey - and a big glass of milk.
meesha says
Hi Joey, I am really sorry that you did not like it ! I had written in the notes in the recipe card that any sweetener can be added, but it is optional. 🙂
