The Toon teenagers netted twice in the first-half at the Magpies' Little Benton Academy, with Fraser Harper opening the scoring towards the half-hour mark before Matheos Ferreira's strike on the stroke of half-time doubled Newcastle's advantage before the half-time break.
Joe Brayson, who was on target in Monday's FA Youth Cup win against Brighton & Hove Albion, added gloss to the scoreline in the closing stages to secure back-to-back wins for Chris Moore's side.
