Schauffele began Sunday's fourth round as one of six players at three under, one stroke back of overnight leader Billy Horschel in the hunt for the Claret Jug.
But the world number three managed six birdies to beat Horschel and Justin Rose by two shots at Royal Troon, making it the seventh straight major to be won by an American.
Back-to-back birdies at holes six and seven put Schauffele in contention, but it was over the back nine where he really stepped things up to pull clear of his rivals.
He took the outright lead on the 13th, sinking a difficult 13-foot birdie putt as playing partner Rose and fellow contender Thriston Lawrence both dropped a shot.
As was the case at Valhalla in May, Schauffele proved an excellent pace-setter, birdying again on the 14th and the 16th then holding his nerve at the death, finding the heart of the green with ease on the penultimate hole to all but seal the deal.
While Rose shot four under and Horschel three under to share second place, Lawrence was one stroke further back at six under for the week, and Russell Henley finished five under after a bogey-free final round of 69.
Shane Lowry, who had led at the start of the weekend but carded a miserable six over on Saturday, rebounded somewhat with a score of 68 to finish sixth.
Lowry said of victor Schauffele: "You need to hole everything on a day like today, especially to beat someone like Xander, who's in the form he's in.
"It looked like he was running away with it again. He did that on me at the PGA, and he's done it again today.
"He just doesn't really hit many bad shots, does he? I went there two back at the PGA, and I felt like I shot a decent score, and I wasn't anywhere near him. He's obviously good when he's out in front."
Jon Rahm joined Scottie Scheffler and Sung-Jae Im as the only other players with a negative score at one under, having briefly threatened a push for the title with three straight birdies to open his final round before tailing off.
