The sweetness of the bananas in this smoothie means you don't need to add any sugar to sweeten the cocoa powder. My kids love this smoothie.
Most all smoothies can be salvaged. This one is no exception. However, the introduction says it needs no sweetener because the banana sweetens it enough. I do not agree. That much banana just makes the banana taste very strong and doesn't allow the peanut butter flavor to come through. I gave this 2 stars (Could be better) because it needs a little sweetener and less banana. Do that and this will be a smoothie that I will make again. - 14 Oct 2015

This was very good, and it wasn't too sweet, which was awesome!! The only thing I added was oatmeal to make it more filling!! - 22 Jul 2016 (Review from Allrecipes US | Canada)
