The Crows – who themselves were celebrating promotion from the SCFL to step four last weekend when they won the play-off final – took an early lead in the league cup showpiece through Rushaar Samuel-Smikle.
But the Robins were soon on level terms through a nice Morgan Vale finish and that was how it stayed until the break.
Will Berry put Hassocks into the lead when he tucked home a corner just after the hour and then Alex Fair produced one of his long-range specials to wrap it up 11 minutes from time.
There were great scenes afterwards as the Robins got their hands on more silverware to end a remarkable season for the Beacon boys.
