Victory for the Trotters saw them lift the Charities Cup.
Kevin Davies set up Ivan Klasnic for the game's opener on 31 minutes before the veteran completed the scoring with a tap-in following Martin Petrov's pin-point cross.
Bulgarian winger Petrov proved to be the star of the show, with an eye-catching display suggesting he is ready and raring to go ahead of the new Premier League season.
He came close to adding a third for Owen Coyle's men late on, but saw his effort cannon off the woodwork.
The Trotters were rarely tested defensively by Houston, with Jussi Jaaskelainen having to make only one save of note - a brilliant low block to deny Danny Cruz in the second half.
Bolton have now picked up silverware in consecutive pre-seasons, with the Charities Cup added to last season's Carlsberg Cup success.
