The youngsters blew away their previously unbeaten visitors on the synthetic surface at Dunfermline High School.
The visitors, with the strong wind at their backs, had two good chances in the opening minutes with keeper Barnett denying both Handling and Hunter.
Cowden however adapted better to the conditions and took the lead after 25 minutes when Chris Hogg fired a low 25 yard shot into the corner of the net.
With the wind us we opened the second half with Callaghan seeing a shot from the edge of the box coming off the bar.
However a second goal soon came on 54 minutes when a Callaghan floated a free kick into the visitors’ box and the ball fell to Dale Finnie who slotted home from close range.
With 65 minutes gone we went further ahead when Nicholson cracked a shot off the post and Ben Anthony fired home the rebound from 10 yards.
Four minutes later it was 4-0 when Jack Nicholson ran in at the back post to head home a Callaghan corner.
Twice in a two minute spell Liam Callaghan saw two long range shots come off the bar but with a minute remaining he was finally rewarded with a goal when he fired home a 25 yard shot.
