I make these all the time. Cook in small muffin tin for 12 minutes and then pop in the freezer once cooled. They are extremely good just slightly unfrozen. We call them Banana Bombs.
Hey Joann,
thank you so much for your feedback! I am incredibly glad that you like my recipe 😉
Have a great day,
Matteo
could i use pb2 or applesauce instead of peanut butter?
Hey Emma,
yes, PB2 mixed with little water until it reaches a smooth, creamy texture (similar to regular peanut butter) should work fine. The brownies however, may not be exactly the same in terms of texture.
Hope I could help 😉
Matteo
This turned out delicious! I used the recipe for a festive holiday treat in my upcoming video, so I will tag you and add the link to your website to the video description and blog post!
Hey Indoora,
thanks so much for your kind feedback. I’m incredibly happy to hear that you liked my flourless banana brownie recipe. Looking forward to the video 😉
Have a great day,

Hey Matt, I made these for my oil free vegan days. Probably the best oil free vegan dessert I have tried. I used tahini instead of peanut butter, and added a tablespoon of maple syrup and some pepitas. Bananas were frozen. Absolutely sensational, even after 2 days. I baked in the airfryer in muffin cases for 20 mins. Thanks for a simple but great recipe that I always have the ingredients
for 🙂
Hey dear Anna,
thank you very much for your kind feedback. I am so glad to hear that you liked my 3 ingredient brownie recipe with bananas 😉
Love the adaptations you made by the way, they sound delicious. Especially tahini, it goes so well with cocoa and sweet bananas.
Have a great weekend,
Matteo
Just made this and it’s easy and all but I am finding it kind of bitter. I think I should have added some maple syrup. Now I think I’ll make peanut butter frosting to counteract the bitterness. But it won’t turn out to be all that “healthy” that way!
Hey Patricia,
thanks for your comment. They may indeed taste quite bitter on their own, but with the addition of extra maple syrup or honey you should get the desired level of sweetness for sure. The frosting is perfect as well 😉
Best regards,
Matteo
Can these be refrigerated instead of cooking?
Hey dear Jan,
thanks for your question. You could theoretically refrigerate the batter without baking. But you will get a sort of edible banana brownie batter, as the brownies won’t harden/ set in the fridge.
I hope my answer could help.
Have a great day,
Matteo
Hi can this be made in an 8 inch pan? Thanks!
Hey dear Betty,
thanks for you enquiry. Definitely, you can use a 8×8 pan but the brownies will turn out slightly thinner. But still very delicious 😉
Have a great day,
Matteo
Can these be made in microwave or air fryer?
Hey dear Olga,
thanks for your comment. I do not recommend microwaving them, but you can air fry them for about 15 – 20 minutes at 340°F (170°C).
Have a great day,
Matteo
Yum! Really good and hits the spot for something sweet/chocolate.
Hey dear Liz,
thanks a lot for your kind comment! I am so glad that you liked my flourless banana brownies 😉
Have a great day,
Matteo
