"The belief is still strong, or we wouldn't be FC Bayern Munich", he said.
Ronaldo said it was a moment to savour.
'I'm happy, I wanted to reach this record. "To be able to reach this mark is an honour and against a team like Bayern it is better still", he added.
Chile worldwide Arturo Vidal headed Bayern into a 26th-minute lead but then missed a penalty on the stroke of half-time.
To make things worse for the hosts, Javi Martinez received his marching orders with 61 minutes played as he saw his second yellow card of the night to weaken his team.
Real Madrid then moved into the lead courtesy their superstar, who stabbed the ball home from a Marco Asensio cross on 77 minutes.
Ronaldo has now scored 97 goals in the Champions League, two in the UEFA Super Cup and one in ECL qualifying.
Bayern suffered a blow before kick-off when top-scorer Robert Lewandowski, who has netted 38 goals this season, dropped out with a bruised shoulder and Thomas Muller deputised as striker.

But the Mail notes that he, rather understandably, doesn't actually want to go to the Chinese Super League. That's how I feel and I'm sure lots of other players are exactly the same.
Asensio's substitution helped Real as he assisted Ronaldo's second goal of the match, which proved to be the victor after the end of the first leg.
"We missed the penalty when we could have made it 2-0, then we conceded right at the start of the first half and that changed the match".
Bayern keeper Manuel Neuer made a number of superb stops to deny Los Blancos from increasing their lead and Ronaldo was full of praise for the German: "I think if Neuer had not been on such form we would have scored more goals". "We would have preferred to have scored another goal", Real Madrid coach Zinedine Zidane told French TV.
One of the only downsides to emerge from their triumph in Bavaria was Gareth Bale being withdrawn in the second half after complaining of a niggle.
"Gareth Bale felt a tweak at halftime and that I didn't need to take any threats", Zidane said.
Vidal also squandered the chance to put his team 2-0 up before the break after he missed a controversial penalty kick when he blasted the spot-kick over the crossbar and into the stands. "With our second half, playing very well, keeping the ball from the opponent and the chances we had, it is clear that another goal would have been better".
"[Manuel] Neuer was good, he made a few saves".
Raphael Varane and Pepe are both sidelined, leaving Real Madrid with only two central defenders available for the trip to Sporting Gijon on Saturday: Sergio Ramos and Nacho.
