I was very skeptical as recipe seems to be missing ingredients - I kept looking for evidence of egg left out of ingredients. I had to cook it way longer than 90 seconds, even with a powerful microwave. I lost track of time but it was at least 3X as long before it looked cooked. I did not weigh my banana so I am wondering if maybe it was too large. I did add 1/2 TBSP SF chocolate chips. I did add the walnuts and the SF syrup on top after cooking. It tastes delicious!

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!

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.

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!
