1. Peel the bananas and cut them into fairly small chunks.
2. Toss these in the lime juice and spread on a baking tray. Freeze until they’re completely solid all the way through – this will take at least 2 hours, but overnight is best.
3. Put the frozen bananas in a food processor with the lime zest, cinnamon, vanilla extract, sugar or maple syrup and the yoghurt or crème fraÎche. Blend until the mixture is smooth and creamy.
4. Serve sprinkled with extra lime zest and cinnamon, if you like.
