The planet with the hottest surface is Venus.

The planet with the hottest core is probably Jupiter.

Explanation:

Mercury is closer to the sun than Venus, so receives more heat from the sun per square metre of surface, but Venus has a runaway greenhouse effect, resulting in a higher surface temperature, about 735 Kelvin.

Jupiter probably has the hottest core at an estimated 20,000 Kelvin or more.
