Bent scored the clincher in a 2-1 win after fighting back from a goal down.
The on-loan Aston Villa striker, who came off the bench to score, said: "It was a positive performance and there's no reason why we can't now go on and have a really good season.
"It was a hard game - you know what you're going to get when you play against Everton. They're a strong side and always make it difficult but I thought we showed character to come back from 1-0 down and get the result.
"The second half was probably the best we've played this season and we thoroughly deserved the win. We'll take great confidence from that performance and now it's all about Cardiff in the league on Saturday.''
