Sunderland lifted the Women's Premier League Cup for the first time with a 2-1 win against Leeds United in the final at Northampton's Sixfields Stadium.
Striker Natalie Gutteridge hit both of the Black Cats goals before Leeds grabbed a stoppage-time consolation through Carey Huegett's penalty.
The result meant that Sunderland completed the double seven days after they had clinched the league title.
Sunderland boss Mick Mulhern said: "It was a great performance."
He added: "Leeds are a tough side who've challenged us all season, but we beat them twice in the league so knew we were capable of doing it again.
"Credit to them though, they never stopped battling and it was a good final."
Leeds boss Chris Welburn said: "We started the game slowly, but were better in the second half and the girls gave it everything.
"Congratulations to Sunderland, they've deserved their double, but we've done really well this season after battling against relegation last year."
Sunderland took the lead in the ninth minute, striker Gutteridge heading in from Kelly McDougall's flick-on following good play by Sophie Williams and Beth Mead.
Captain McDougall wasted the chance to double the lead when her 30th-minute penalty was saved by keeper Julianna Draycott after a foul on Mead by Leah Galton.
Left winger Galton was relieved to see the spot-kick saved and then, three minutes before half-time, she almost equalised with a 20-yard shot that flew just over the bar.
But 21 minutes into the second half Leeds went further behind when Gutteridge headed her second goal from an excellent Williams cross.
Player of the match Williams was denied a deserved goal when Draycott saved bravely at the winger's feet in the 88th minute.
Leeds' consolation goal arrived three minutes into stoppage time, Huegett netting from the spot following a hand-ball by midfielder Rachel Furness.
