Carlo Ancelotti’s side moved on to 66 points from 28 games, extending its lead at the top to 10 points over second-placed Sevilla, who were held to a 1-1 stalemate at Rayo Vallecano on Sunday, a sixth draw in their last eight league matches.
Vinicius Jr opened the scoring in the 55th minute after a defender lost the ball on the edge of the box and Benzema set up the Brazilian to strike.
Vinicius was then tripped inside the area 22 minutes later and Benzema converted the resulting penalty.
The French striker scored again in the 82nd minute with a header from a Marcelo cross, but got hurt in the process and asked to be substituted, pointing to his left ankle.
