Tips: The cake can be baked up to 2 days ahead. Let it cool completely, wrap it tightly in plastic, and store it at room temperature before frosting and decorating. The frosting can be made up to 1 day ahead and refrigerated; bring it to room temperature and re-whip until fluffy before using. Once decorated, loosely cover the cake and store it at room temperature for up to 1 day, or refrigerate it for up to 3 days (the coconut may lose some of its soft texture).
