Speaking after, Cibulkova was at a loss for words when asked to explain how she won the match.
"I have no words, coming here for the first time, the biggest tournament of my life,” Cibulkova said in her on-court interview.
“I still don't know how I won, I put the ball over the net and it went in, it's the happiest moment of my life."
Cibulkova is now the first debutante to lift the title at the season-ending showpiece since Petra Kvitova in 2011, and the achievement will see her climb to a career-high world number five when the new rankings are released on Monday.
