Hibs were thrashed by their Edinburgh rivals Hearts in the showpiece occasion which compounded painfully the fact that they have not won the tournament since 1902.
However, after almost single-handedly taking the Easter Road side through a pulsating quarter-final encounter at Rugby Park by taking his tally to 22 for the season, the striker, who is on loan from Wolves, said: "It is not just me who is the Hibs fan, Paul Hanlon is as well and we know what it means to the Hibs fans to win the cup.
"We have the chance to rectify that now. If we get through the semi-final then hopefully we can go one step further.
"The gaffer spoke to us after the game (against Killie) on Wednesday to tell us how important this game was going to be and to get back to Hampden.
"Last year we said, 'is it going to be this year and what better way to do it than against Hearts' and we got absolutely humiliated. We embarrassed ourselves and most of all the club last season and we just have to rectify that. It was probably the biggest derby there will probably ever be and it was a shambles really.
"Fair play to Hearts they won it, they played better than us on the day. But we are not going to talk about the final just yet, we have important league games coming up starting against Hearts next week."
Killie boss Kenny Shiels claimed the visitors must have thought they had "won the lottery" due to his side's poor defending.
He said: "We have performed remarkably well this last while but you have to give Leigh Griffiths a lot of credit, you can't overlook that, but the basic defending of long balls was really, really poor and that was the key.
"We looked the team that was trying to play with invention and creativity but if you can't defend straight balls like that...they must have thought they had won the lottery. It was unbelievable, really poor."
