If you are not in a hot climate your cake will last longer if you don't put it in the fridge. Refrigeration makes cakes go stale quickly. Coconut will go brown only if it is fresh coconut, desiccated coconut should be fine.

It may not have to be refrigerated after opening - but it will probably retain it's moisture and flavor better if it is. If the bag recommends refrigerating after opening, then do so.
you can make coconut cake
After baking the cake, let it cool. Wrap the cake well in plastic wrap. Refrigerate it until ready to serve. Remove the cake from the refrigerator at least an hour before serving, bringing the cake to room temperature.
