The Welshman, who came off the bench for Real Madrid in the second half of the Kiev final, struck an overhead kick over Loris Karius to put his side 2-1 ahead, leaping several feet off the ground to meet the ball with incredible athleticism.
Cristiano Ronaldo has now won five in his great career, but even he could not argue that this was Bale's evening.
Bale, dropped to the bench by coach Zinedine Zidane, is facing an uncertain future at the Santiago Bernabeu after a hard season with the Spanish giants.
Cristiano Ronaldo has hinted that he could leave Real Madrid this summer following his side's victory over Liverpool in the Champions League final.
But it was an even quieter night for Mohamed Salah, with the Liverpool forward lasting only 30 minutes before being forced off with a shoulder injury that now threatens his participation at the World Cup with Egypt.More news: NY parents win legal battle to evict son, 30
Bale scored the third goal after another error by Karius. The Bale error was another lack of concentration when it mattered most.
Jurgen Klopp's and Liverpool's own evening was marred by the loss of a distraught Mohamed Salah to injury in the first half, the Egyptian coming off half an hour in having damaged his shoulder.
"That hasn't happened this season for one reason or another".
It had been uncomfortable for Real, but after Salah departed, they sensed their chance.
Indeed they were level just four minutes later, Dejan Lovren's towering header from a corner poked in by Sadio Mané at the back post.
Mane's pace gives Liverpool the ability to trouble any team, but the real blow caused by Salah's injury was that to Liverpool's self-belief.
