The television presenter surprised Dorothy Gaffney, 71, from Knightswood, after her shift shepherding pupils safely into Garscadden Primary and St Brendan's Primary schools.
Carol brought the crossing patroller a hot pie as part of a new campaign to celebrate the meat treat.
Carol, the face of the campaign, said: "What better to warm you up and cheer you up on a dreary day than a piping hot pie?
"It has become an iconic food in Scotland and you can't beat the combination of golden pastry and tasty meat filling for a treat - a steak pie is my personal favourite.
"People like Dorothy are working outside in all weathers at this time of year and we're calling on butchers, bakers and consumers to recognise deserving members of their local community and put a smile on their faces with a pie."
Pie fans across Scotland are being encouraged to follow Carol's lead and treat friends, family or colleagues who work outdoors in the chilly January weather. Butchers and bakers across Scotland are also being urged to reward unsung heroes in their local communities with a tasty pie.
The campaign - a collaboration between industry bodies Quality Meat Scotland, Scottish Bakers and the Scottish Federation of Meat Traders Association - will be running in butchers and bakers up and down the country.
Members of the public can also nominate deserving recipients online using #welovepies - the 100 best will each receive a free pie.
Alan Clarke, chief executive of Scottish Bakers, added: "Last week was the Scotch Pie Awards and over 500 different pies and savouries were submitted to be judged. I have to say the standard of the entries was exceptionally high this year."
