In the bottom of an 8x8 inch (20x20 cm) pan, place a layer of about 20 lemon wafers. The wafers should overlap. For the next layer, spread 1/3 of the coconut cream on top of the wafer. Next, layer 1/2 of the lemon, curd, and then 1/2 of the coconut pudding. Repeat once more in this order: wafers, cream, curd, pudding. Lastly, place another layer of wafers, and then top with the last of the coconut cream. Decorate with toasted coconut or crushed wafers, if desired.
