That would be Pluto-Charon. While Charon is usually though of as Pluto's largest moon it does not actually orbit Pluto. It is close enough to Pluto's mass that rather than Charon orbiting Pluto, the two objects revolve around their common center of mass, which lies between them, above the surface of Pluto. Keep in mind that Pluto is no longer considered a planet.
None. Pluto-Charon was almost considered one in 2006, though that would be a dwarf double planet rather than a true double planet as Pluto is not a planet. In billions of years the Earth and Moon will be a double planet. Also, the question is non-sensical because if it was a double planet then they would both be planets... so there would be no moon. A planet would be considered a double planet with it's opposite planet, not moon.
