With Hampden out of commission due to the forthcoming Commonwealth Games, the match took place at Celtic Park.
The teams played out a 0-0 draw in a tense encounter of few chances before Derek McInnes' men won the shoot-out in front of 51,143 fans.
Adam Rooney scored the decisive penalty as the Dons won 4-2 on spot-kicks to claim their first silverware since 1995/96.
