Palace went behind midway through the first-half but rallied in the second to secure a 2-1 victory at the JobServe Community Stadium.
Weerden drew the game level on 60 minutes with a fierce strike that hit the underside of the bar before nestling in the net.
Half-time substitute Larkin would then score the winner on 83 minutes, with her effort also crashing against the woodwork before landing in the corner of Natalia Negri's net.
