Can I add eggs somehow and reduce the peanut butter?
Hey Ben!
You might replace 60 grams (1/4 cup) of nut butter with one whole egg, but you may need to adjust the consistency of the batter with some extra (oat) flour in case it gets too liquid. I personally have never tried it, however.
Let me know about the result, in case you try!
Have a great day,
Matteo
I made this today, I added sugar free chocolate chips and it was amazing. Thank you for the recipe, this will definitely be a regular in our house.
Hey dear Gina,

Could I add an egg for extra protein or is would that mess with the texture/taste?
Hey dear Megan,
thank you for your comment. You can think about replacing one banana with one egg!
Have a great day,
Matteo
Did you melt your peanutbutter before adding it or is it just naturally a little more liquid?
Hey dear Melody,
thank you very much for your comment. As I used natural peanut butter, it was already smooth and quite runny. So I did not need to melt it before. In case your nut butter is too hard (which I do not recommend), it is a good idea melting it beforehand!
Kind regards,
Matteo
Hi Matteo,
Thanks for sharing this amazing recipe, is so delicious and simple!
Best regards,
Megan
Hey dear Megan,
thank you very much for your comment. I am glad you appreciate!

You didn’t add any sweetner !! so , does the sweetness come from the bananas or now a days we do get sweetned peanut butters, can they be used ?
Hey dear Nitin,
first of all, thank you for your comment.
As far as your question is concerned, I did not use any additional sweetener. I personally find that the natural sweetness from ripe bananas is already enough. Also, I did not use any sweetened peanut butter.
If you want sweeter brownies, however, of course you can adapt this recipe with some extra maple syrup or honey.
Sweetened peanut butters can also be used!
I hope I could help you.
Have a great day,
Matteo
Absolutely amazing! So tasty and really simple. My peanut butter was thick and crunchy so I used extra and some maple syrup to thin it abit more. I also added some cut up curly Wurly for an extra treat.
Hey Danielle!
Thank you very much for your feedback, I am incredibly happy to hear that you enjoyed 😉
Have a great day,

Delicious! I used powdered peanut butter and added water + chocolate chips and it was great!
Hey Lily,
Thank you very much for your kind feedback. I am extremely happy that you liked.
Have a great week to come,

Will be using powdered peanut butter too ?
Such a great recipe. I love to add a lil bit of black walnuts and a bar of dark chocolate (made into lil chunks). It’s so good. We prefer it over regular brownies any day. ?
Hey my dear,
thanks a lot for your feedback!! I am so glad that you liked this recipe 😉
Have a fantastic day,
