Add the pistachios to a blender and blitz until crumbed. Add a third of the frozen bananas and mix until combined and smooth.

Fill the ice cream moulds a third of the way up ( I filled 5 ikea push lolly moulds) but this will obviously vary depending on the size of mould and size of bananas.)

Add the cherries to the blender and blend, add a third of the bananas and mix until combine and smooth.

Fill another third of the ice cream moulds with the cherry ice-cream.

Add the remaining bananas and cocoa, mix until combined and smooth. Fill the ice-cream moulds.

Freeze until solid. (I froze mine over night)
