Adrian's howler gifted Willian the opening goal 13 minutes in and there was no way back for Jurgen Klopp's side after Ross Barkley doubled Chelsea's lead in the second half.
Kepa Arrizabalaga impressed on his return to the Chelsea team, making a flurry of saves in quick succession in the first half on a frustrating evening for a much stronger Reds side than they fielded in previous rounds.
Newcastle reached the last eight for the first time since 2006, ending their goal drought to beat Championship leaders West Brom 3-2.
The Magpies had gone three games without a goal, but Miguel Almiron's first-half brace and Valentino Lazaro's finish put them three up.
