Full-back Jack hit a thunderbolt in first half injury time before fellow defender Kevin scored his first goal for the Academy in the second half.
It was a typical goal-fest of a game from the Under-18s, whose 27 matches in the PAL have now reaped 122 goals - an average of over 4.5 goals a game!
Norwich took an early lead and there was then a lengthy break in play as Giancarlo Gallifuoco was forced off after a clash of heads.
Jack Munns levelled, Kenneth McEvoy and Jack Barthram made it 3-1 and it then went 3-2, 4-2 through Kevin, 4-3 and finally Souleymane Coulibaly wrapped up the win with the fifth.
"We were caught inside the first minute, a situation we could have defended better," reported coach Alex Inglethorpe.
"Jack Munns levelled direct from a free-kick after 15 minutes. It's something he works on a lot in training and this time he spotted a gap in in the wall and kept his shot low.
"We went 2-1 up soon after when Kenneth McEvoy hit a cross-come-shot from the right that was deflected home.
"Jack Barthram made it 3-1 in added time with a fantastic goal. It was one of those where he had space 35 yards out and just unleashed an unstoppable shot.
"Norwich hit us on the counter-attack five minutes into the second half but we made 4-2 straight away with Kevin Stewart's first goal for us.
"Jack Munns swung in a corner, Kenneth got on the end of it, the goalkeeper parried and Kevin was there for the rebound. We're all delighted for him because he's done ever so well for us in his two years at the club.
"Norwich got back into it again at 4-3 with about 15 minutes left but we then sealed it with 10 minutes left as Jack Munns released Souleymane Coulibaly through on goal and he finished well with his left foot.
"I thought we were excellent for the majority of the game, we really hit the heights.
"It takes time for the players to learn the way we want to play and sometimes you reap the benefit later in the season, rather than earlier.
"I'd also like to give a mention to Harry Voss, who is an Under-15 player and did well for us in goal. It was a fine performance for someone giving away three or four years in some cases. That bodes well for the future."
Spurs U18s: Voss, Barthram, Gallifuoco (Lameiras, 19), Stewart, Smith (Ward, 83), Ball, Bentaleb, Munns, McEvoy, Zapata-Caicedo (Oduwa, 72), Coulibaly.
