Scally and Finn seal Cork's spot
Cork 1-16 Dublin 0-13
Orla Finn and Eimear Scally combined for 1-10 as holders Cork qualified for a 10th successive Division 1 final at Nowlan Park.
The Rebelettes continue to hold the Indian Sign over rivals Dublin, as they inflicted yet another knockout defeat on the Sky Blues on Saturday.
And while Cork boss Ephie Fitzgerald might still be without dual stars Briege Corkery and Rena Buckley, there's still a significant depth of talent in his squad.
Finn top-scored at Kilkenny's Nowlan Park with a haul of 0-7, including four points from play, as Scally collected 1-3 from play.
Cork were 1-10 to 0-6 clear at half-time, with Scally and Finn collecting 1-6 between them, and all but one point of Cork's first-half tally came from play.
Dublin got to within one at one stage in the opening period as Sinead Aherne (free), Rebecca McDonnell and Nicole Owens scored points. Owens was unlucky not to find the net in the 21st minute, but Martina O'Brien pulled off a fine save.
Dublin suffered a blow when Niamh McEvoy went off injured and although she was fit enough to return for the second-half, that seven-point half-time deficit was too much for the Dubs to claw back.
They did manage to cut the Cork lead to three points with five minutes left, but the Leesiders found an extra gear.
