Mathew Barzal and Derick Brassard also scored for the Islanders, who are 2-0-2 in their last four games. Semyon Varlamov made 28 saves to earn his 16th career win against the Stars, his most against any opponent.
John Klingberg, Denis Gurianov and Jason Dickinson scored for the Stars, while Ben Bishop made 37 saves.
Dallas, vying for a sweep of its three-game trip to the New York area, took a 3-2 lead 6:56 into the third period as Klingberg’s shot from near the blue line managed to beat Varlamov. It was his first goal since Dec. 1.
Brock Nelson appeared to tie the score with 5:27 remaining, but the goal was taken off the board after Dallas challenged for goalie interference.
The Islanders’ power play finally broke through on its fifth opportunity of the night. With Roope Hintz penalized for holding, Barzal tied it with just under four minutes remaining. The 22-year-old leads New York with 12 points in eight games at Barclays Center this year.
Beauvillier then beat Bishop on a breakaway in the extra period as the Islanders improved to 5-0-3 in Brooklyn this season.
Beauvillier opened the scoring 90 seconds into the game, beating Bishop with a backhand shot from the right side. It was his fourth goal in the last seven games. The goal also marked the eighth straight game that the Stars had allowed their opponent to score first.
New York had two power plays in the first 10 minutes of the game, but were unable to double their lead.
The Stars capitalize where the Islanders couldn’t. With Casey Cizikas sitting for interference, Gurianov tied the score at 1-1 with 5:52 left in the first. The goal was Gurianov’s second against the Islanders this season.
The Islanders outshot the Stars 18-7 in the first.
New York failed to score on two early power plays in the second. The Islanders came in converting just 12.1 percent of their power plays over their last 16 games, ranking second to last in the NHL over that span.
Dickinson beat Varlamov from the slot with 7:48 left in the second period to put Dallas up 2-1. Dickinson has scored twice in his last three games.
Dallas’ lead didn’t last for long though, as Brassard tied it just 86 seconds later, snapping an 18-game goal-scoring drought.
