The £16.5million signing has scored nine goals so far this season.
Bent said: “That’s my first hat-trick for five years, since I played for Ipswich at Walsall.
“My mum’s run off with the match-ball for safe-keeping! It’s easily my best night for Spurs and I’m loving the responsibility of being up front on my own.”
Manager Harry Redknapp added: “It’s a terrific return getting nine goals and hopefully he can keep going.”
