Goals from Chad Pillar, Mitch McKay, Aaron Hogg and Connor Ingram saw Windmill beat 10-man CSKA Emneth 4-2 in extra-time in the final of the Norfolk Sunday Senior Cup at Carrow Road.
The Great Yarmouth Sunday League champions had been beaten in their previous two finals in 2013 and 2014, but it was a case of third time lucky this time as they came from behind to see off their King's Lynn League opponents.
Windmill went behind when Aaron McKenna's thumping header found the back of the net, with Pillar levelling on 32 minutes. A minute later Windmill grabbed another thanks to substitute Mitch McKay.
CSKA lost David Abbott to a red card but with seconds remaining Lewis Thompson beat Taurean Molloy from the spot.
Windmill got their noses in front again in the first period through Hogg before the game was finally settled by young striker Ingram.
