The North London club took the lead within 20 minutes following terrific, determined work from Nabil Bentaleb on the left.
After maintaining possession in his own half with multiple passing exchanges, the Frenchman held off Moussa Sissoko. His subsequent cross was parried by Tim Krul straight to Emmanuel Adebayor, who prodded it into the gaping goal.
Seven minutes into the second half, Bentaleb and Adebayor were involved in putting their side two-nil up.
The former picked out Paulinho's smart run just in front of the Newcastle defence. The Brazilian flicked it to Adebayor and was then quick on the uptake to tuck away the striker's rebounded shot.
Newcastle showed signs of life at this point, inspired by the arrival of Hatem Ben Arfa. With Spurs sitting back, the home side missed its opportunity to engineer a frantic finish to the game with Hugo Lloris denying them from close range.
Adebayor made it 3-0 with a well-taken volley on the 82nd-minute mark. Substitute Nacer Chadli completed the scoring with a curled effort into the far corner to complete a miserable night for Krul and his team.
