The defending League Cup holders made light work in their semi-final with their second 4-0 win over Liverpool this season.
Wales captain Jayne Ludlow gave the Gunners an eighth-minute lead, then three minutes before half-time England striker Lianne Sanderson doubled the advantage with her 21st goal of the season.
England winger Rachel Yankey added the third goal in the 68th minute and Republic of Ireland defender Yvonne Tracey completed the scoring six minutes from time.
Everton sealed their place in the FA Tesco Premier League Cup final after seeing off Watford with a last minute winner in extra time to make it 2-1. The results set up a repeat of the 1999 League Cup Final, which Arsenal won 3-1.
