I think it's Neptune.
None of the planets we know have a complete snow covering; Earth has only a partial and seasonal snow covering for only a fraction of its land area. Saturn's moon Enceladus (which is not a planet) comes close as it is known to have water geysers because of subsurface liquid water - some of which water falls to the surface as snow, and some escapes into space. The outer planets also have some amount of water ice in their atmosphere, although the effect would not dominate enough to be described as being covered with it.
Most of the colder plants from earth beyond to the next sun have ice but not necessarily snow.
If you mean the precipitation of frozen water then only Earth.

What snow planet?
About 3/4 of a billion years ago ... the ice-ball (or snow ball) Earth, when the entire planet was covered in snow & ice, the seas frozen.
In usual text, snow-covered would probably be hyphenated - otherwise the sentence could be misinterpreted - consider the difference between the concept of "snow-covered mountains" and the sentence "snow covered mountains".
Pure As the Blood Covered Snow was created in 2003.
