Newcastle were struggling to place any real pressure on the Toffees who struck the woodwork three times in four minutes during the second half.
Barkley, in his 100th Premier League outing, stepped up and converted from 12 yards before Jamaal Lascelles was sent off for a last-man challenge on the Toffees midfielder.
Barkley this time produced a cheeky panenka finish from the spot to take his tally to 11 goals for the campaign and cap off a fine display which could have easily brought about three or four goals.
