Goal Sports and Edgehlll Reserves will contest the final of the League Trophy after they beat Sherburn and Duchess in their respective semi-finals.
Goal Sports beat Sherburn 4-0 to make the final in their first season in existence.
Mark Plumpton's side led 1-0 after 30 minutes, George Friend's driving run forced him into the box and he forced a save from the Sherburn keeper, which fell straight to Kieran Friett to lash in from six yards.
Friend then got his name on the scoresheet after Dan Pollard danced through the Sherburn defence and pulled it back for Friend to fire his side into a 2-0 lead that they carried into the break.
The home side's dominance continued after the break when Friett turned provider, feeding Friend to grab his second, before the scoring was wrapped up as Friett grabbed his second with a volley over the keeper from long range.
Plumpton said: "I'm absolutely buzzing. To get through to a cup final in our first season is a great achievement and it'll be a great game against Edgehill Reserves in the final."
Friett and Friend were the victor's star men.
Edgehill Reserves await Goal Sports in the final after they took a 3-0 lead in the first half and never looked back at Duchess.
The away side took the lead after just two minutes when the referee pointed to the spot after a foul on Tom Scales in the box and player-boss Martyn Ferrey stroked home the resulting spot-kick.
It was soon 2-0 when Benny Davis played in Scales to calmly roll under the Duchess keeper and the same player rounded the scoring off at 3-0 after Lee Dennis' corner was flicked on by Davis' glanced header and Scales fired in from close range.
Edgehill's Craig Love was sent off with 25 minutes left on the clock.
A delighted Ferrey said: "I can't single anyone out, it was a great team performance from the lads.
"We'll give Goal Sports all the respect they deserve in the final. Mark Plumpton sets his sides up well and they always try to play good football, so we'll need to be on our game."
