The forward entered the fray five minutes into the second half of this 80-minute encounter and struck the spot kicks firmly beyond the reach of goalkeeper David Grof after Jonathan Obika had twice been brought down in the box.
This was the lads' third friendly in four days and they held firm against a physically strong Hibernian outfit, created more chances and ultimately deserved their win.
Takuta Mtandari and Ajet Shehu had half-chances from corners before a spectacular save from Grof kept Obika at bay from 20 yards. Hibernian's best chance arrived on 23 minutes when Jordan Cropley played a one-two with Kurtis Byrne only to fire only.
Alec Olsen headed just over from Mason's cross five minutes into the second half and the breakthrough finally arrived after 63 minutes via Mason's first penalty.
Grof denied Obika again with Ali Park clearing off the line before Dean Parrett tapped home the rebound, Mason struck the foot of the post but didn't have to wait long to find the target again with a second successful spot kick four minutes from time.
Ryan Mason kept a cool head to score twice from the penalty spot as our Academy team beat Hibernian 2-0 in Saturday's friendly at Spurs Lodge.
