BITE Me Mini Donuts mobile food service has been operating in the Hawkesbury for 22 years, and is one of a number of food trucks frequenting 'pop up' sites around town.
Business owner Rowan Smith from Kurrajong said the nature of her business was "fluid", travelling to local businesses and schools that want "something special" to break up their day.
Bite Me Mini Donuts operates out of South Windsor, but has a food truck selling hot, cinnamon and sugar-covered donuts and slushies.
"We go week by week with our plans at the moment," Ms Smith told the Gazette.
"If you're a business in the Hawkesbury we can come along and make your staff have that 'warm and fuzzy' feeling - they can hire us for two hours.
"We're also popular with schools. We have a COVID safety plan in place and have public liability. We don't handle any cash and we don't have any contact with the students - we make our hot and fresh donuts on site and with the help of the P&C we distribute them to the students."
She said making the offerings affordable was crucial to being able to trade alongside businesses and schools, offering morning tea to get workers' spirits up or something special for a school group.
Bite Me Mini Donuts is one of a number of food trucks and mobile food trailers that has made use of the vacant lot on the corner of Hawkesbury Valley Way and George Street, Windsor, on weekends for the last month.
Different types of food trucks park on site every Saturday and Sunday, from 11am until 8.30pm.
