Jordan Speith became the 2015 Masters champion at the age of 21 after leading the event from start to finish.
Spieth's 4 shot overnight lead helped him on his way to taking his first Masters and Major title.
He faced little pressure early on which may just have helped to settle his nerves.
The in-form champion made 2 early birdies at holes 1 and 3 to extend his lead early on. Justin Rose did keep up with Spieth by making birdies at 1 and 2 but a dropped shot at 6 saw him remain 4 back and another at 9 saw Spieth's lead grow to 5.
Dustin Johnson made an early charge on the final day reaching 9-under-par after 12, but his poor 3rd round and end to day 4 meant he was just too far back.
Rickie Fowler's final round 67 saw him tied for 12th, his strong finish means he has finished in the top 10 in his last 5 majors.
The chasing pack never seemed to put enough pressure on Spieth. His front 9-35 gave him a 5 shot cushion, which was a great platform to move forwards.
Tiger Woods and Rory McIlroy failed to make a significant move on Sunday and finished a few too many back.
Rory McIlroy played some good golf on the closing day, finishing with a 6-under-par-66 but a slow start to the week saw the world No1 finish 8 back.
Japan's Hidieki Matsuyama's final round 66 was good enough to see him reach -11, the 23 year old has played The Masters twice as an amateur but 2015 sees his best finish.
Spieth's 26th birdie of the week at 10 saw him extend his lead to 6 with my 8 holes to play. His fantastic second shot into the par-5-13th saw him make yet another birdie and extend his lead to 5 again after he had dropped a shot at 12.
Mickelson hit a fantastic shot to hole out from the bunker on 15 to pile the pressure on Spieth, the roar of the patrons must have been heard by the leader.
Spieth's poor tee shot at the par-3-16th looked like it would see him drop a shot, but with Justin Rose unable to capitalise on a great tee shot, Spieth rolled in his par to remain out in front by 4 with 2 left to play.
Spieth made a record breaking total of 28 (after15) birdies which saw him pass Phil Mickelson's previous record of 25. His final score of -18 was the joint lowest in Masters history, his performance this week has broken so many records this week its hard to keep track of them all, but one thing is for sure he deserved to break them.
A great performance saw him take a comfortable lead onto the 18th, and a steady hole meant he could enjoy the walk up to the green under the watchful eye of his parents.
Only 3 players have ever held a wire to wire lead but 21 year old Spieth has been breaking records left right and center this year.
Jordan Spieth showed great composure on Masters Sunday, his attitude and performance this week have been world class. He holed some amazing putts and recovered overtime he needed too which gave him the edge. He is a worthy champion and I'm sure we will see plenty more of him!
