  • I was sceptical about this as it seemed too easy and too good to be true. I was sooo wrong! It was dead easy indeed, and fabulously tasty. I only replaced the walnuts with berries (just to save a few calories, but otherwise the walnuts go better with the banana flavour). Thank you for this recipe, loved it!

  • This is my go-to banana bread recipe now (minus the walnuts due to allergies). I suggest to get a little daring and throw some chocolate chunks in there… I promise you won’t be disappointed.

  • One of my favorite protein desserts! I make this every couple weeks and it’s perfect every time. Great with ice cream if you can spare the macros. I normally put the walnuts in the batter rather than on top. So tasty!
