Hibs closed the gap on second placed Rangers to five points with their biggest win of the season as they over-ran Cowdenbeath in a game which the Capital club dominated from start to finish.
Paul Hanlon and, inevitably, Jason Cummings with his sixth goal in his last five matches - making it 12 in all for the season - had Hibs two up at half-time but it took until the 74th minute for them to emphasis their superiority with a terrific solo goal from Scott Robertson.
Callum Booth made it four and in added on time Lewis Stevenson made it five, the two full backs enjoying rare goals for the club.
Jordon Forster made a surprise appearance on the Hibs bench after three months out with a broken foot and then an emergency appendix operation but there was no place for new striker Franck Dja Djedje who was suffering from a slight hamstring injury.
Alan Stubbs’ side were on the attack from the start and took only nine minutes to make the breakthrough, Cowdenbeath goalkeeper Robbie Thomson failing to deal with Scott Allan’s corner, the ball finally falling for Hanlon to hook into the roof of the net.
Hibs almost doubled their tally in the 18th minute when Callum Booth, operating at left back rather than on the right, set off on a lung-bursting run which took him into the Blue Brazil’s penalty area, his cutback finding Cummings who was unable to direct it on target with Thomson caught flat-footed.
Cummings then fired off a left foot drive which rose just too much before, inevitably, he got his name on the scoresheet, in the right place at the right time yet again to turn Scott Allan’s low cross into the net from inside the six yard box after good work from Dylan McGeouch.
The Hibs teenager clearly fancied more and he forced Thomson into a good save at his near post with a vicious drive after he’d cleverly worked room for himself on his favoured left foot.
Hibs began the second half where they had left off, Cummings firing a low ball across the six yard box with no-one there to take advantage before the youngster again stung the fingers of Thomson with another blistering shot from 18 yards out.
It had become very much akin to a training match for Hibs with Cowdenbeath carrying no threat whatsoever, a long-range shot from Lewis Milne which flew well wide their only attempt on goal with some 58 minutes gone.
However, it all made for a rather dreary second 45 minutes with the home fans urging their side to make their dominance count.
And they did so in the 74th minute with a superb solo goal from Robertson, the midfielder managing to keep his feet as he evaded a string of tackles before sliding the ball into the far corner, reminiscent of his finish against Rangers the other week.
Booth made it four with a first time finish from ten yards and in added-on time Stevenson added a fifth with a low shot into the corner.
