The Nigerian forward eventually got his goal in the 73rd minute after producing a brilliant solo run through the Dunfermline defence before calmly finishing to make it 3-0.
Josh Cooper pulled one back for Dunfermline seven minutes later with his first touch after coming on, but it proved only a consolation for the Championship side.
The victory capped a remarkable finish to the season for Celtic, who had already secured the Scottish Premiership title last weekend.
