Second-half substitute Morias - who signed a professional deal in the summer - found the net with a powerful effort after some fine individual work.
This came after a trialist had headed home a Josh Scowen free-kick in the opening 45 minutes.
"It was an encouraging performance," said player-coach Gareth Ainsworth, who played at centre-back and right-back after coming on a sub on the hour mark.
"We could have had a few more goals, but it was another great experience for the younger lads. A good night's work."
Squad: Ingram, Trialist (Ehui 45), Hause, Trialist, Trialist, Scowen, Kewley-Graham (Kretzschmar 45), Ighorae, Trialist (Ainsworth 60), Angol (Morias 45), Taylor.
