Spurs took full advantage of Liverpool’s shock defeat at relegation strugglers Bournemouth beforehand to boost their top-four hopes after disappointing exits in the FA Cup and Champions League in the last 11 days.
Kane’s first-half double, which took his Premier League tally to 20 goals this season, and Heung-Min Son’s second-half finish put Spurs 3-0 up after 62 minutes.
Forest scored a late 81st-minute consolation through Joe Worrall’s header, with substitute Andre Ayew missing a stoppage-time penalty that was saved by Fraser Forster.
Defeat for Steve Cooper’s side leaves them three points above the relegation zone having won just once away from home in the Premier League this season.
