The 21-year-old midfielder signed a six-month loan deal at the Wham Stadium on 31st August and was joined by United team-mate Luke Charman later that day.
Both players started on the bench against Burton Albion at the weekend, and while Charman remained there throughout the game, Barlaser entered the fray in the 62nd minute.
His side were trailing at the time, but earned a 1-1 draw thanks to Billy Kee's 84th-minute penalty. The result continued Accrington's steady start to life in League One following promotion last season.
Meanwhile, in League Two, defender Josef Yarney made his eighth start for Morecambe - but the Shrimps were beaten 1-0 at home by Swindon.
The international break meant no action for Dwight Gayle, Jack Colback or Rolando Aarons, who joined Czech side FC Slovan Liberec on Friday, while Henri Saivet's Bursaspor met Sivasspor in a friendly, which finished 1-1.
