Veera Kauppi made her first full game in a month out due to injury.
Then the big star accounted for two goals when she first equalized at 1-1 in the first period and then made it 5-2 in an open box with four seconds left to play.
Thorengruppen had to fight for victory in an even final as TPS reduced to 2–3 but when the opposing team chased an equaliser, Emelie Wibron extended the lead with six minutes left to play.
Then Kauppi, who was also responsible for an assist in the final, determined the final result and the Thorengruppen became the best in Europe in floorball.
The Champions Cup title is the team's first.
Thorengruppen also tops the SSL where they have won 15 out of 15 matches.
