Defrosting a cake

I made this cake back in September, but it was huge! So I froze half of it.

I am currently in the process of defrosting it now...

(I had to Google "How to defrost a cake" - but it wasn't very helpful...)

Update to come...

UPDATE: Due to my improperly-freezing of the cake (should have wrapped the cake in saran wrap before wrapping it in foil, defrosting the cake in my fridge under the foil leflt the cake ... gummy with melting condensation from the foil! Too bad! I ended up throwing away half of the cake (that I had worked so hard to bake)... Next time, I'll just have to bake for an event or occasion :) instead of randomly baking a massive cake...
