Speaking as a PPL Examiner......
Standard stall recovery..... Reduce angle of attack and once aircraft is flying smoothly and progressively apply power ensuring that you apply rudder as required. Then pitch up and climb.
It does not need a massive pitch down, just enough decrease its AoA to start lying again.
Generally speaking if the stall Warner has gone off the aircraft is flying again. Think about the scale of where the stall Warner goes off, its above the actual stall so as soon as it stop you are no longer stalled and can then apply the power part of the recovery.
If you apply power at the same time as the pitch change I would fail you as you are effectively trying to drive out of the stall rather than proper recovery.
So.....
Reduce AoA, get flying, apply power climb away. Simples.
As far as a PPL skill test is concerned as an examiner we should only ever being doing the standard stalls not trying to push the extremes of the envelope.
