A hat-trick from Steve Crawford gave Dunfermline all three points in a rollercoaster game at East End Park.
Crawford, left out of Scotland's squad for the friendly with Denmark, took his goals superbly to send a message to national coach Berti Vogts.
Dunfermline started brightly and took the game to Dundee. Gary Dempsey had a chance to put Dunfermline ahead after four minutes but he sent his back-post header over the top with the goal at his mercy.
Jason Dair and Dempsey were also wayward with long-range shots as Dunfermline put the Dundee goal under threat.
But it was the visitors who snatched the lead in 21 minutes. Dunfermline were short at the back and Fabian Caballero fed Nacho Novo who drilled a 16-yard shot past Marco Ruitenbeek.
Novo had another goal disallowed six minutes later with referee Iain Brine ruling that he had pulled the shirt of Andrius Skerla before he put the ball in the net.
Dunfermline equalised in 33 minutes with a superbly-worked goal. Dempsey hared down the right and produced the perfect cross for Crawford to direct a 10-yard header behind Julian Speroni.
Dundee were back in front in 58 minutes when Novo chased a long clearance out of defence and touched the ball past Ruitenbeek, who had raced out of his box, before finding the vacant net.
Dunfermline were back level ten minutes later when Sean Kilgannon crossed for Craig Brewster to head home.
The home side went for the kill in the closing stages and Crawford nabbed his second when he lobbed Speroni in 79 minutes.
Novo blotted his copybook when he was sent off for two bookable offences with eight minutes left.
Crawford completed his hat-trick five minutes from time with a shot which hit the post before going in
