There is something you can do as well. Specially, kids love it, and you can just keep them in the freezer.
All you need to do is cut the bananas in half and put a wood skewer in them, as if it was some kind of lollypop.
Put them in the freezer for 30 mins. Meanwhile, melt some good quaility chocolate.
Take the bananas out of the freezer, dip them in the chocolate (you can also have some chopped nuts ready to roll them after the chocolate). And back to the freezer.
You can eat them straight from the freezer!!!.
I saw once a recipe where they were using chocolate and them crushed oreo biscuits...must be very nice as well.
