Take ripe bananas, peel and cut them into thin slices
Place in container, cover, and leave in freezer until solid
Blend until it achieves the consistency of frozen yogurt
Add peanut butter, chocolate powder, milk, or anything else that catches your fancy
Every time I make this it tastes pretty strongly of banana (as would be expected), so you definitely have to be a fan of them to like this. Also, never, ever use under-ripened bananas; it will taste awful, I guarantee it.
