Healthy, Easy Delicious Banana Bars

Oh, the bananas. We keep buying them and eating them, while also allowing countless more to go brown on the countertop.  

So I keep coming up with new ways to use them up. If you are reading this, it’s likely you, too, have some bananas waiting to be mashed and mixed into a delicious treat.

You came to the right place. I found inspiration for a new banana recipe while (re-)making my 3-ingredient Almond Oat Focaccia Bread the other day. Almond flour and oats work in delicious harmony in the recipe. I decided I needed to test drive the combination with some bananas in the mix. 

My banana experiment–Oat and almond flour bars, for breakfast, snacks or dessert– passed the test with high marks!

Oil-Free, Gluten-Free, Banana-Sweetened Bars

Looking for a banana bar recipe that has it all? This one does. Ironically, it does so with very little. Specifically, five familiar ingredients:

You can reduce it to four ingredients by leaving out the chocolate chips, or up it to 6 or 7 ingredients by adding a smidge of cinnamon or vanilla.

The fat from the almond flour makes these bars moist and tender, without the addition of any oil. Whoohoo! And with 1 and 2/3 cups mashed, ripe banana, there is no need to add any additional sweeteners.

How to Make Healthy Oat Almond Banana Bars

Ready to make these bars? You won’t need much time or effort.

Begin by mashing enough ripe bananas to measure 1 and 2/3 cups (425 mL). Mix the bananas with 1 and 1/2 cups (135 g) of rolled oats.

It will take about 3 to 4 large bananas to equal 1 and 2/3 cups mashed. I prefer to give the exact measurement for the bananas. Bananas vary (a little or a lot). Size matters (at least in baking :)), so for accuracy, it is best to use standard measurements. 

Let the oats and bananas stand for 15 minutes. Meanwhile, preheat the oven to 350 F (175 C) and line  a 9-inch (22.5 cm) square baking pan with parchment paper (I spray the exposed interior sides).

Once 15 minutes have passed, vigorously stir the banana-oat combination to break down the oats and create a creamy, more homogeneous mixture.

Add the remaining ingredients–almond flour, baking powder, and optional salt–to the bowl. I decided to add about 1/2 teaspoon of cinnamon, too.

Stir until all of the ingredients are completely combined and then spread in the prepared pan, smoothing the top.

Chocolate chips and bananas are made for one another, so let their relationship flourish by sprinkling 2 to 3 tablespoons of the former over the surface of the bars.

You can use regular size chocolate chips, but I prefer the miniature variety, for maximal coverage.

If you like, stir the chocolate chips into the dough before spreading in the pan. Alternatively, double the chocolate chips, adding some into the dough and some on top!

Bake, Cool and Cut the Bars

Bake the bars in the preheated oven for 22 to 25 minutes until set at the center and golden brown at the edges. Transfer the pan to a cooling rack and cool completely.

Once cooled, use the parchment paper lining to remove the bars to a cutting board. Cut into 16 bars or squares.

Be sure to eat one immediately. Because I said so :).

Can I Use Frozen Bananas in the Recipe?

Yes, frozen ripe bananas can be used in place of fresh, ripe bananas.

Keep in mind that, as the bananas thaw, they will release liquid. Do not drain the liquid! Include the liquid in the measurement of the bananas.


Happy Baking!

HI Camilla: 2 questions: If I have a non stick coated pan, do I have to use the parchment paper? Also, did you use the GF oats or regular rolled oats? Thank you, June


Friday 4th of September 2020

Hi June, No need for parchment paper if the pan is nostick. However, I still like to use parchment paper, just because it makes lifting the bars out of the pan easy. You can do wither :) I always us GF oats when I bake. But if someone does not need GF, they can use regular oats.

I’m a huge fan of this almond flour and rolled oat combo. I‘ve made the focaccia as written and as thin crisp bread a number of times now! So today I went to make this banana version and realized I had no chocolate chips... but I did have some strawberries at the end of their life. I sliced them and folded them in at the end, and it was wonderful. Great texture and naturally sweet. Thanks so much for all your great recipes!

so glad that this was a winner, Penny! The addition of strawberries sounds delicious!

I’m not one to usually comment, but these bars are SO GOOD! I don’t always gravitate towards banana bread or GF&oil free breads because I can’t stand dense and dry breads. I’m new to trying out healthier baking alternatives. This makes such moist bread! I have a sweet tooth so I added a small sprinkle of coconut sugar and cinnamon on top before baking, but it really wasn’t even necessary. I would definitely use this as my standard banana bread recipe just on taste alone!

I am so happy that these were such a pleasant surprise, Emilia! Thank you for letting me know (yum, the coconut sugar-cinamon topping does sound super-delicious!)

Thanks Camilla, I used blanched almond meal in this recipe and I really like the subtle sweetness it gives, another depth to the banana. I didn't have choc chips and it is still good without. I also made a choc 'icing ' using protein powder, cacao, cashew butter annd almond milk. Tasted great on the warm bar.

Sounds so good, Mary! Your description of the frosting is making me hungry!

would this work with quick cook steel cut oats?


Tuesday 10th of March 2020

Hi Carolyn,

Yes, definitely, but with two caveats (1) you'll either need to weigh your quick cook steel cut oats (use the same weight as for the rolled oats). If you do not have a scale, you'll need just under 1 cup of the q-c steel cut oats (the Bobs Red Mill Steel Cut Oats, quick-cooking, are 36 g per 1/4 cup, or 144 g per cup); (2) you'll need to grind the oats in a food processor or blender. They do not need to be ground super-fine. I would love to know how it works out!
