Just a minute into the game being played at a sun-bathed Petershill Park, City thought they had got off to the perfect start when Leanne Ross hit the back of the net, however it was ruled offside.
But five minutes later and City took the lead after a great ball from Eilish McSorley found Jo Love who lobbed Sangster who came rushing off her goal line to put City ahead.
Just a few minutes later and the Dons keeper pulled off a superb save to deny Amy McDonald from close range, before Jo Love fired wide from the resulting corner.
The first chance on goal for Aberdeen and ultimately their only one of the game saw Claire Martin fire a shot from 35 yards out, but it never troubled Alexander in the City goal.
A minute later Jane Ross tried her luck from distance also but her shot just sailed over the bar, with Sangster watching the ball all the way.
With Aberdeen stubbornly defending against City who were dominating possession and camping out in the Dons half, City captain Rachel Corsie teed up herself from 35 yards out, but her shot just shaved the top of the bar and out for a goal kick.
City’s dominance finally paid dividends as they doubled their lead through Julie Melrose as she swivelled inside the box surrounded by Dons defenders before firing home on 26 minutes.
Eddie Wolecki Black’s side continued to have their chances on goal and Jane Ross scored her first and City’s third firing home from an acute angle.
City should have had their fourth soon after, but after finding herself unmarked in the box Leanne Ross could only fire her shot wide of the goal when it would have been easier to hit the back of the net.
However, they did make it 4-0 soon after with Jane Ross scoring her second of the game, when Christie Murray fired a low ball across the six yard box before Ross latched onto it and fired low under Sangster.
Soon after she hit her hat trick, her second in three matches, when she pounced on a rebound after Sangster had saved from Rachel Corsie, to fire home City’s fifth.
The second half was less than a minute old when City made it six, with Eilish McSorley and Jo Love combined well for the City midfielder to finish superbly against the helpless Sangster, it was near identical to Love’s first goal as she received a long ball pass from McSorley, before lobbing the Dons keeper.
Great movement and crisp passing between McSorley and Love set up Julie Melrose, who was free at the back post, but her shot went wide of the target.
With the game well and truly over as a competitive spectacle, City made a triple substitution, Corsie being replaced by Lisa Evans, Love by Ciara Barnes and former Hibernian midfielder Leanne Crichton came on for hat trick hero Jane Ross.
It wasn’t long before Lisa Evans showed her class and threat in front of goal when she scored City’s seventh of the game, getting on the end of a pass from Emma Fernon, before firing past Sangster.
Evans doubled her tally, minutes later as she beat the keeper to the ball, before rounding the keeper to make it 8-0 to the reigning SWPL champions.
With 15 minutes remaining Nicola Docherty struck the post, before Christie Murray was brought down in the box and Patrick McAuley had no other option but to award a penalty. Leanne Ross stepped up to take the spot kick, but Sangster pulled off a superb save to tip the ball round the post and out for a corner.
But City were not to be denied their ninth of the game, as substitute Ciara Barnes struck a superb shot from inside the Dons box beating Sangster, who must have been wishing for the end of the Dons reality check.
