If you have a Vitamixer, be sure to use the tamper and keep an eye on it. When you start out, it's kind of crumbly but in no time it turns creamy. Amazing transformation!
If you use a blender or food processor, definitely be sure to scrape it down (I think a food processor would work better). I haven't tried it with either, but have seen recipes online for frozen banana ice cream using a food processor.
If you're a vegan, you'll love this dessert!
Until I can get a better picture up online, this is the one I took today. We had it with coffee (I had mine with wine - I was on a roll!).
