I think it is more appropriate to name this cake just as 'Topo map cake' for the layers in this cake really look like a map. Layering this cake can be quite challenging as a great deal of patience is required. But patience and endurance do pay and after the cake is baked and once you sliced it up, you'll be so pleased to see the pretty layers and the colour combination. Not only does it look awesome, the texture is good too, soft and moist.
