Tony Watt doubled Celtic’s lead midway through the first half with an opportunist strike from ten yards out.
Patrik Twardzik scored on the stroke of half time from a Callum McGregor pass shortly after Darnell Fisher had replaced the injured John Herron.
Ten minutes into the second half a shor cum cross from the left by Patrik slipped through the home keepers hands. At the other end Robbie Thomson saved a penalty but Killie pulled a goal back in bizarre fashion when a block challenge on a Filip Twardzik clearance arched over Thomson into the net.
Patrik restored Celtic’s four goal lead with a great shot past the keeper from a Watt pass.
