The Magpies scored twice in two minutes in the second half to see off the Trotters who saw a similar thing happen to them at Fulham just nine days ago when they conceded twice in a minute to lose 2-0.
It was a match of few chances but one that was successfully taken came in the 69th minute when Ryan Taylor got a cross in from the left for an unmarked Hatem Ben Arfa, who had come on less than ten minutes earlier, with the French winger firing home from just outside the six-yard box for his first league goal of the season.
Bolton's fate was decided just few minutes later when Cheick Tiote intercepted in midfield before releasing Gabriel Obertan down the right where he found Demba Ba who got in a deft touch which took a slight deflection for his 14th of the campaign.
Earlier, Taylor forced a good save from Jussi Jaaseklainen in the 14th minute when he curled a long range free-kick with the Finn punching away at the near post before Martin Petrov got Bolton's first shot on target when his curling shot from a short free-kick was brilliantly saved by a diving Tim Krul late in the first half.
In the 50th minute, Krul did well to cut out a Petrov cross from the left just in time to deny Gary Cahill a scoring chance as Newcastle were unlucky not to take the lead eight minutes later when Obertan made a positive run down the right before turning onto his left and forcing Jaaskelainen into a crucial save.
However, the two goals in quick succession came for Alan Pardew's men who remained seventh on the table but managed to record their first win in six outings as Owen Coyle and Bolton stay rooted in the relegation zone with a 14th loss from 18 matches so far this term.
