The reason I love this dessert is that the texture is so creamy. You get the consistency of ice cream without the cream and fat. So if you like the flavor of banana and you like ice cream, then this will be your new favorite dessert. And if banana isn't one of your favorite flavors you can add other yummy things to it. This one I made with black berries, but one of our favorites is to just toss in some strawberry jam. I've done peanut butter, and any fruit would be great. I also throw in a tablespoon of milk for consistency sake. If I don't, my food processor never quite gets past the chopped up frozen fruit stage.
One other tip I have for you is on how to freeze your bananas. I don't recommend throwing in whole, unpeeled bananas into your freezer. Coming from experience, they are a pain to peel. I find the best method is to peel your banana and break it into 1-2" chunks and spread them out on a cookie sheet. Then place the cookie sheet in the freezer and you have easy to get to goodness. We use our frozen bananas within the same week, but if you won't get to all yours within the first couple weeks of freezing, I recommend storing them in a container once they have frozen on the cookie sheet.
Hope you enjoy experimenting, and the best part is, it's really good for you!!
Let me know if you come up with any great tasting variations :)
