Tyler Walker netted an extra-time winner for the Championship club to condemn United to their first second-round defeat in this competition in 27 years.
But it was half-expected by many Newcastle fans as Rafa made TEN changes to the side that lost to Huddersfield on Sunday.
The manager - as usual - opened the door to ANOTHER cup defeat against lower opposition.
The the two teams had shared four first-half goals, with Aleksandar Mitrovic and Rolando Aarons having scored for United.
Newcastle manager Benitez made 10 changes for the second-round tie, which was watched by a crowd of 27,709.
Mitrovic gave United an early lead with a fierce shot from an Aarons cross.
But Forest capitalised on some uncertain defending either side of the half-hour mark to take a 2-1 lead.
Jason Cummings first stooped to head a Zach Clough cross past captain Karl Darlow.
Then he latched on to a long ball forward from Danny Fox before lifting the ball over Darlow, signed from Forest three years ago.
Aarons, however, capped a superb first-half performance with a stunning equaliser from outside the box.
Newcastle pressed and pressed for a winner after the break, but they couldn't force a breakthrough and the game went into extra-time.
Walker got a touch on Jack Hobbs' goal-bound header in the 98th minute to put Forest into the lead.
And there was to be no way back for United, who have now lost three successive games this season.
