The fixture, a repeat of last year's showpiece, will be held on Wednesday 10 October (7pm kick-off) at Barnet FC's Underhill, with the game to be televised live on ESPN.
Blues will be looking to gain revenge for last year's 4-1 loss to the Gunners at Burton Albion. David Parker's side progressed to this latest final with a 2-1 victory over Lincoln Ladies earlier this month.
