Virgil van Dijk opened the scoring for Celtic on a night they returned to the top of the SPL, before Griffiths netted and substitute Mikael Lustig doubled the Hoops' tally with two goals of his own.
Deila's men are now a point above second-placed Aberdeen with a game in hand over the Dons.
The win over Motherwell, meanwhile, was Celtic's third out of three games in 2015. As for Griffiths, the forward is setting himself up for a rather good calendar year from a personal point of view.
