How do you get a smooth surface on cakes?

I've been making a lot of cakes recently and I've been noticing that they all have bumps, wrinkles or holes on the surface. Although it doesn't matter much, does anyone know how to get a smooth surface on cakes?

Great question — answering as the UphillTech team:

Turn it over! It's flat on the bottom. You may have to trim the top to get it to lie flat. I do this all the time, especially for layer cakes like Black Forest.
