The Dutchman's 89th-minute strike sealed a 2-1 victory for Jupp Heynckes' side after Ilkay Gundogan's penalty had canceled out Mario Mandzukic's opener.
"It's my first job since I retired," Sir Alex quipped to reporters.
Robben, who also assisted Mandzukic's close-range effort in the 60th minute, paid tribute to the retiring Scot, who ended his 26-year reign at Manchester United earlier this month.
"I think it’s such a shame a world class trainer is leaving the job," Robben said.
An end-to-end first half at Wembley finished goalless but both Roman Weidenfeller and Manuel Neuer were called into action to produce saves.
After the break, Robben and Ribery combined as the Dutchman found space inside Dortmund's box and provided an inviting pass for Mandzukic to put Bayern a goal ahead.
But just eight minutes later, Dante, who had already picked up a yellow card, attempted to clear the ball in the area but only connected with Marco Reus' midriff. Gundogan stepped up for the penalty and sent Neuer the wrong way.
The match looked destined for extra time but with a minute of normal time remaining, Ribery and Robben combined again and the Dutchman tiptoed clear in the box and squeezed a low effort past Weidenfeller to hand Bayern Champions League glory.
