Aleksander Zniszczol, Bartlomiej Klusek and Krzysztof Biegun scored a total of 755.5 points to claim victory and follow in the gilded footsteps of the Polish ski jumping stars.
Malysz took two gold medals on the same slopes in the Dolomites at the World Championships in 2003, while Stoch topped the podium at the same event earlier this year.
This next generation of promising Polish jumpers, led by Biegun, edged Russia's Roman Sergeevich, Alexander Sardyko and Mikhail Maksimochkin, who had to settle for silver with a score of 727.7.
The Austrian team, consisting of Daniel Huber, David Unterberger and Clemens Aigner took bronze with 721.9.
“This is everyone’s victory," Biegun, 19, said. "We believed we would win since the very beginning and we were good enough as to keep well focused."
Poland also struck gold in alpine skiing as Maryna Gasienica-Daniel won the women's giant slalom in Pozza di Fassa.
And Austria picked up another silver after an aggressive second run by Michele Morik. Sweden's Veronica Elaine Smedh came back from fifth after the first run to claim bronze.
Gasienica-Daniel said: “I'm the happiest person in the world. It’s a very important victory and I want to dedicate it to all the people who are close to me. It wasn't an easy race, this course was really demanding, but I managed to stay focused and find the right pace."
And as the curtain was brought down on the nordic combined competition, Poland grabbed yet another gold, in the team Gundersen event.
Szczepan Kupczak, Pawel Slowiok and Adam Cieslar outpaced Slovenia (Borut Mavc, Joze Kamenik, Matic Plaznik) and Japan (Go Yamamoto, Shota Horigome, Aguri Shimizu) to clinch victory on a highly satisfactory day for Poland.
In biathlon, Russia's Larisa Kuznetsova, Tatiana Semenova, Sergei Kliachin and Aleksandr Pechenkin eased to victory in the mixed relay, consisting of two six-kilometre legs for the women and two 7.5km runs for the men.
The Russians crossed the line nearly a minute and a half ahead of their nearest rivals, the Ukrainian team of Varvynets, Iana Bondar, Vitaliy Kilchytskyy and Dmytro Pidruchny.
The Czech Republic's Jitka Landova, Kristyna Cerna, Michal Zak and Tomas Krupcik took bronze.
“At the shooting range, Larisa Kuznetova and I were very concentrated and we used only two extra bullets without taking any penalty," said Semenova. "Afterwards, the boys were both fantastic at the shooting range and at skiing. Aleksandr Pechenkin was perfect - no extra shots. We are very happy".
Alexis Keeney won slopestyle gold for the US in freestyle skiing, with Switzerland's Fabienne Werder settling for silver and another American Katie Souza bronze.
In the men's event, Finnish favourite Kalle Leinonen was victorious with Poland's Szczepan Karpiel second and the Netherlands’ Janne Van Enckevort third.
On the ice, China and Korea tasted success in the 1,500m short track finals in Trento.
In the women's race, Chinese Jiaying Tao sped home in 2:30.296 to claim victory with Hungarian Bernadette Heidum (2:30.545) taking silver and Korea's Hwang Hyunsun (2:30.606) bronze.
"The secret of my success? I'm not under pressure," Jiaying said.
In the men's race, Noh Jinkyu won with a time of 2:16.810, ahead of his compatriot Um Cheonho (2:16.852) and Canadian Yoan Gauthier (2:17.742).
And finally in speed skating, Dutchman Pim Cazemier won the men's 10,000m and Japan's Miho Takagi the women's 1,000m.
Cazemier, who has already stepped onto the podium at the University World Championships in Zakopane in 2012, earned his country a first gold of these Games after he raced past Korean Lee Jin Yeong - who won bronze in the 5,000m - in the final laps.
Bronze went to Russia's Evgeny Seryaev.
“That's my first important international medal," said Cazemier. "I was already on the podium of the University World Championships, but today it was a fantastic race, with a great time."
Takagi edged Korean Kim Hyun Yung and Russia’s Angelina Golikova for her victory in the women's race.
