Forson has struggled for game-time in recent weeks, having joined the Championship side from RB Salzburg this season.
He failed to make it off the bench in the club's previous seven league games and also started this game as a substitute before his introduction in the 84th minute, for Kellen Fischer.
Forson bagged two goals in stoppage time to secure a dramatic win and steer his side into 11th place on the league standings with 36 points from 26 games - four points of the playoff places.
Milan van Ewijk had opened the scoring for the visitors to Carrow Road with 24 minutes on the clock.
Speaking after the game, the Canaries' boss said on Ghanasoccernet: "It hasn't been easy for him. He's a new player in a new country who hasn't been in the side much recently.
"He has found it difficult to settle, as many players do in this situation, but the other players have helped him, and to have that happen at the end was very special for him.
"I normally tell players not to take too much notice of what the press says after games, but on this occasion, I have told him to take it all in. It is well deserved."
