Get your ripe bananas, peel them, and slice them into smaller pieces.

Spread the banana pieces on a plate so that they don't overlap. Put it in the freezer until the banana has frozen (approximately 2 hours).

After the banana has frozen put it in the food processor and blend until it becomes a smooth puree.

If you want, you can add whatever flavour you want and blend it in.

Put the mixture in a plastic container and place in freezer for an hour.
