Tommy Mooney ended a 10-game goal drought as he earned Wycombe a draw.
Barnet failed to test Wycombe keeper Jamie Young in the opening half while Wycombe looked toothless without the injured Jermaine Easter.
Barnet broke the deadlock on the hour through Liam Hatch after a mix-up between Sam Stockley and Young.
The Bees were content to waste time but Wycombe finally found the goal they deserved when Stefan Oakes' cross was met by a glancing Mooney header.
