The 35-year-old was in superb form at this year's edition, storming to the title without dropping a single set throughout the tournament.
Croatia's Cilic was also hampered during their encounter. "And I'm happy I kept on believing and dreaming and here I am today for the eighth".
13 - Federer won all 13 of his service games against Cilic and broke his opponent five times.
"It's definitely great for me to be in the final of a Grand Slam again", Cilic said.
Serena Williams has not competed since January because she is pregnant, and by losing rankings points she earned a year ago by winning Wimbledon and reaching the French Open final, she drops to No. 15, out of the top 10 for the first time since April 1, 2012.
This was the first grand slam men's singles final in the open era between a number three seed (Federer) and a number seven seed (Cilic).
Federer's record at the other two Slams - the Australian and US Opens - follow a similar pattern.
Roger Federer's Wimbledon triumph in numbers
You sense in the wide-eyed wonder Federer sometimes expresses about his own game, he now plays tennis for the same reason Yo-Yo Ma plays the cello - just to experience that sense of near perfection few will ever know. Federer gave his first big hint that he was on his way to big things here by upsetting Sampras in the fourth round in five sets in 2001.
"It's just belief that I can achieve such heights, and you know, I wasn't sure I was ever going to be here again in another final after past year". You feel like you have to reinvent the wheel.
"But, otherwise, it didn't hurt so much that it was putting me in tears".
"Also I was just not able to set up properly on the balls". And even then, the question is not whether the name Roger Federer belongs with Muhammad Ali, Michael Jordan, Donald Bradman, Jack Nicklaus, Pele et al.
Of course, the knock on his claim of supremacy is Nadal's head-to-head "dominance" over the 35-year-old. But it has been eight years since she last appeared in the final two and nine years since she last lifted the trophy. "I can't ask for more, but I want a little more". Cilic is beginning to utilize his energy to great impact, returning intensely and drawing a mistake from Federer for 0-15.
Fourteen years on from his first victory, there were signs of nerves when he served for the title for the first time since 2012. This will also only be their first clash on the grass surface. However, Blake Ellis, 18, remains in the tournament in the boys doubles draw.
"They come for the finals".
