Dutchwoman Cornelissen, who had already qualified for the final in Sweden by virtue of being the defending champion, delighted her home crowd at the Brabanthallen with victory atop Jerich Parzival.
It was the 33-year-old's third win of the 2012-13 season, following Odense and Lyon, and it came as she revealed a new freestyle routine for the first time.
"I need to change some small things, and we are still getting used to the new test but I’m very happy because with Parzival it is all getting much lighter and more harmonious” she said.
Her effort impressed judges and spectators alike and she claimed victory with a score of 85.9 per cent ahead of her compatriot Edward Gal.
Gal, with Glock’s Undercover, scored 85.1 per cent.
Germany's Isabell Werth, with Don Johnson FRH, came in third with 79.475 per cent to leap from eighth to joint third in the overall standings and secure her place in the final in Gothenburg, which runs from April 24 to 28.
Anna Kasprzak with Donnperignon placed fourth with a score of 78.650 per cent, and the Dane will also compete in the final after rising from 11th to eighth overall thanks to the result in the Netherlands.
