The teenage midfielder is one of a number of young players showing immense promise under Jackie McNamara, alongside the likes of defensive pair John Souttar - like Gauld just 17 - and 19-year-old Andy Robertson.
On Saturday Gauld's double strike, along with one each for Paul Paton and Robertson, guided the Tannadice club to sixth in the table.
Their cause was aided by some poor defending by a makeshift home back-four which had to contend with three changes, with the ever-present of trio of Simon Ramsden, Stevie Hammell and Shaun Hutchison missing through injuries and suspension.
However, there was no denying the quality of the visitors' performance, described by Motherwell manager Stuart McCall as "the best of any visiting team" during his time at Fir Park.
Gauld, though, did not revel in his own spotlight but instead praised his team-mates.
He said: "It was a great team performance and we're happy to come away from home and win 4-0 but I think it could have been much more.
"We had plenty of chances in the first half and didn't take them."
It has been a significant few days for the teenager, who has extended his contract with the club until 2016 and whose performances have been rewarded with a call-up to the Scotland Under-21 squad to face Georgia on Thursday.
He has also been linked with a number of other clubs, with some reports indicating interest from Real Madrid.
Gauld said: "It's been a very good week for me, signing the new contract and getting called up to the Scotland Under-21 squad.
"I don't listen to the speculation. It's flattering to hear but I just forget about it as soon as I go into training or come to a game.
"The manager has been excellent with us and I'm sure there's many more young boys he's ready to give a chance."
The youngster might also have claimed a hat-trick had McNamara not substituted Gauld with over 20 minutes remaining after the youngster suffered a slight head knock.
The United boss was thoroughly delighted with his side's performance and the number of chances their flowing football produced, but he explained why he had taken Gauld off.
McNamara said: "I was reluctant to take him off but Ryan took a bit of a dunt before his first goal and felt a bit sick at half-time, so we took him off before the end for his own sake and hopefully he will be okay for the Scotland Under-21 game."
