Spread a thin Nutella layer on a crepe and sprinkle some desiccated coconut. Spread some strawberry sauce and desiccated coconut on a second crepe and place it on top of the first one. Continue the same pattern alternating between the two spreads until all the ingredients are finished. Top with lamington pieces and strawberries. Serve the crepe cake soon after. I prefer eating it straight away rather than after it has been chilled in the refrigerator.
