An early goal from Fiona Lafferty set Donaghmoyne on their way to victory over Carnacon and their third All-Ireland Senior Club Championship title success.
Driven on by Cora Courtney, Donaghmoyne attacked the Mayo champions from all angles and they led 1-5 to 1-3 at half-time.
Catriona McConnell scored a point immediately after the break and moments later Donaghmoyne were awarded a penalty after Carnacon goalkeeper Michelle Higgins took down Niamh Callan.
McConnell hit the post but Lafferty followed up to drill the ball into an empty net.
A freakish goal from Natasha Beegan threw Carnacon a lifeline, but as Majella Woods (2), McConnell (2 frees) and Courtney all posted points to put the issue beyond doubt.
