The Catalan club took advantage of Real's goalless draw at Rayo Vallecano to move just three points behind.
Lewandowski, who only returned last week with a brief substitute appearance after a muscle injury sidelined him for a month, scored his first goals for Barca since the end of September.

Inter and Roma took full advantage with 2-0 victories against Lazio and Udinese, respectively.
