Step 1: Into a large saucepan put milk, sugar, eggs and bananas and then blend with a stick blender (if you don't have a stick blender then use a blender or food processor and then transfer to saucepan) heat over a very gentle heat stirring frequently until the custard thickens (should coat back of wooden spoon with a thick mix and when stirring leave a trail), add arrowroot to help thicken even more.
Step 2: Spread the custard out on a tray (with sides) to let cool completely.
Step 3: Preheat oven to 180°C.
Step 4: Cut pastry sheets in half and place pastry sheets on baking paper lined trays.
Step 5: Prick pastry sheets all over with a fork.
Step 6: Place in oven and bake for 10 minutes.
Step 7: Give cooled custard a stir to (don't worry about it having formed a skin), put down a layer of pastry and top with 1/3 of the custard but don't take it right to the edge, put on another 1/3 layer of custard and then another pastry sheet and then the final layer of custard and the final 4th sheet of pastry.
Step 8: Sprinkle with icing sugar and then refrigerate for 1 hour.
Step 9: Remove and slice into desired portions (3 to 4).
