Healthier Chocolate Chunk Banana Cake (Gluten Free)
We love this moist and yummy banana cake for any party or when we have those ripened bananas on the counter.
We couldn’t get over the texture and flavor of this cake. So simple to throw together in one bowl and beyond delicious and fluffy.

If you don’t have oat flour ready, you can make it yourself in a food processor with rolled oats. Just pulse them until they resemble a flour consistency. If you don’t have espresso powder, just skip it! The cake will still taste incredible!

You can use a chopped up chocolate bar or chocolate chips. Or even use nuts and seeds as an add in. The olive oil can be subbed with avocado oil or melted butter.

This looks amazing! Is it possible to replace the oat and almond flour with regular? I’m not against using it, it’s just not something I have in the house and I barely ever bake but this has ignited a craving in me!
Hi Ellen, yes, I would start off with 2 cups all purpose flour and then add if needed. All purpose flour is much more absorbent than almond flour so you will probably need a bit less of it to get your batter to the right consistency.
perhaps, but then it’s not gluten free, for us gluten intolerant people.
Made the oat flour as suggested and this came out perfectly. This is a different way to use bananas outside of a standard banana bread.
Hi Melissa, so glad you enjoyed the cake recipe! And thanks for taking the time to rate it!!
oat flour is not gluten free
Mine is!
it can be. gluten free oat are available, although much more expensive 😁
Υπέροχη συνταγή, την έχω φτιάξει 4 φορές για την οικογένεια μου(μέχρι στιγμής)
Πολύ εύκολη και γευστική <3
can wheat flour replace almond flour?
amazing
Thanks so much for trying it out!
This cake is absolutely delicious!! I followed the recipe including the espresso powder. I think I would add more espresso powder as I am an espresso lover. For the chocolate, I used the Hu Dark Chocolate Bar with almond butter and puffed quinoa along with a couple of sprinkles of Ghirardelli semi sweet baking chips. This cake is as delicious as it looks! No regrets on making this one! My family loved it and I’m sure I will be making it again soon. Thank you, Stella!!

Absolutely delicious!!
HI Laura, glad you liked the cake! Thanks for the rating!
Hi, I was wondering if that’s normal but for this recipe there is not the option to see metrics ? it is quite long to put everything in grams myself, that’s why I usually love your website 🙂
Hi Anissa, so sorry about that! I just updated the recipe with the metrics. Enjoy!!!
Can I substitute zero calorie sweetener for the honey?
Hi Ashley, if its a liquid like honey
Just made this and it is OH SOOOOO DELICIOUUUSSSS 🤤
It’s a melt in your mouth and hits all the right spots healthy dessert! Thank you for your recipes! 🤗
Stumbled on to your page today and I am already a fan!
I’m making the lazy spanakopita tomorrow ☺️
Simple to follow recipe, baked for 35 minutes, lovely and light cake. Loved it, thank you. An Australian
Hi Angela, thanks so much for the lovely rating! Glad you liked the cake!
Can you use only almond flour in this recipe instead of oat and almond?
Hi Heidi, You can absolutely sub in more oat flour or All purpose flour in lieu of the almond flour. But definitely decrease the amount when using fine powder like flours.
This person asked if you could use almond flour only, and I was wondering the same. Would measurement change?
Would change the composition and since I haven’t tried it with all almond flour, I cannot recommend it. Sorry
Hi Stella – can you please clarify your answer to the original question of “can almond flour be used instead of almond and oat flour?” I think you may have misread it. Thanks!
Hi Debra, I cannot recommend all almond flour since I haven’t tried it myself and my experience with all almond flour baking is that it can be tricky. Most times you have to use a thickening agent like tapioca flour along with coconut flour to absorb liquids in the recipe. Its typically not a straightforward ONE to ONE ratio in substitution. Sorry I can’t be of more help!
Hi! Can I use almond flour with regular flour instead of oat flour?
Hello! yes you can!
This cake was absolutely delicious! I made it exactly as indicated and just substituted the olive oil for avocado oil as you suggested and used non dairy chocolate chips vs chunks although I think I may do the chunks next time and use some cocoa powder. This is a great way to use bananas and not waste them.
I had a question about the metrics, is that per serving or for the whole cake and if per serving, what is the serving size? Thank you so much again for sharing this Stella!
Hello! This looks extremely delicious and can’t wait to try it out!
I have a question about the nutrition information – it says 372kcal. is that per 100gm?
it tatses amazing yet still a healthier option
Hi Juliana, yesss thank you for trying it!
Could this be made into muffins?
HI Riley, I dont see why not! Go for it! less time obviously
Good idea, will try same
I have always been terrible at baking but this recipe was so easy to follow. It was delicious!!!! Thank you for this recipe!
Hi Maria, love that you enjoyed making it!
I have made this for my family 3 times now and they love it!
Can I freeze it?
Hi Bess, that’s awesome! I haven’t tried it but should be fine!
Thanks for the recipe. Just wondering if expresso powder same as instant coffee? Many thanks.
Hi – yes its the same!
Hi 👋 my son has a banana allergy do you recommend sweet potato or pumpkin as a sub ?
Hi Nicole, yes, I would recommend either one!
Looks yummy. Are the nutrition facts per serving (8) or the whole cake? I think this question has been asked a few times but I don’t see an answer. Would really like clarification. Thanks 😊
Hi Teri, nutritional info is per serving (not the whole cake)
Hi Stella,
I am hooked on this recipe as I love both expresso and chocolate chips! I just have a question, your nutrition information says Calories: 372kcal. is that for one serving? (8 servings per cake)
Hi Diana, yes that’s correct!
This was great. Easy to make. Very low on sweetness which is what I prefer. Will absolutely make this again. I like it better than my traditional banana bread
Exactly! I’m the same way! Glad it was enjoyed and thank you for the rating!
I really want to make this cake but I don’t use almond flour enough to justify buying a bag right away. Can I substitute almond flour with regular flour and make my own oat flour from rolled oats?
Instead of expresso powder, can I use instant coffee granules?
Hi Cathy, yes thats the right substitute!
Perfect
Thanks for the rating!
Absolutely amazing! Melts in mouth
Hi Gergana, glad you liked it!
super, hvala!
love it!
Delicious
Wow!! What a great cake! It’s so flavorful and moist! I didn’t have super high expectations for this gluten free cake but it is really perfect. It needs no changes. Just make it and love it.
so chocolatey and addicting
I love it…. Simply delicious
I am baking it again tomorrow:)
Fantastic
loose texture, not too sweet, and the chocolate puddles – oh my!
hi stella, the cake looks great!my familly will definitely like it!
im not sure about the almond flour – it seems like 177g= 0.75 cup. but i know that 100g=1 cup. am i wrong?
hi Stella, it looks great!
Can you please check the ingredients list again? its written that 177g of almond flour= 0.75 cup. However, as far as I know , 100g= 1 cup. Am i wrong?
We are obsessed with this banana bread. Do you think I could swap the banana with pumpkin purée at the same ratio with some spices and still have it turn out?
Can I substitute gluten-free flour with the oat flour 1:1? Thanks!
Hi Brenda, yes go for it!
