Clara enjoyed a dream start with a goal from close-range by Hogan inside the opening 60 seconds, followed by quick-fire points from former All-Ireland winner Conor Phelan and Hogan.
Scores from Stuart Mullins and powerful full-forward Kevin Sexton got the Plunketts’ account up and running but points from centre-forward James Nolan (three) and Hogan (two) gave the Noresiders a 1-8 to 0-4 interval lead.
The Dublin champions did make a real fight of it after the restart but Clara had that little extra in the tank, though, as points from Lester Ryan, Hogan and Chris Bolger helped to ease them over the line.
