Microwave the chocolate until almost completely melted (or do this over a low heat in a pan), then stir until melted, smooth and shiny. Pour onto a plate or a wide, shallow bowl.
Pour desiccated coconut onto another plate or wide shallow bowl.
Place lolly sticks into the cut part of the bananas, then dip in the chocolate and roll in the desiccated coconut, before placing onto a tin-foiled or baking paper lined tray.
Place tray into the freezer and leave until the chocolate is hardened and the lollies feel cold, ideally at least an hour. Serve straight from the freezer.
