Nine products are being sold through Co-op deli counters, including family-size 1lb pork pies, meat and potato pies, small steak pies and pasties.
Huntsman and Scrumpy pies from the company's Speciality range, as well as individual quiches Lorraine and cheese and onion quiches will also be stocked in the delis.
The new business is currently worth around £10,000 a week, according to MD Roger Topping, who runs the business with his wife Maggie.
The company, which also supplies Booths and around 170 Asda stores, aims to further increase business with the major multiples after investing around £500,000 to double the size of its factory to 10,000sq ft.
"We expect to hit turnover of around £2m for 2010/11, but we have the capacity to reach £3m," said Topping. "We do a limited number of pre-packed products at the moment, selling to independent retailers, but we are working with Sheffield Hallam University's design team on new packaging for next year. There's definitely potential for pre-packed products in the supermarkets under the Topping brand or as own-label."
Topping started out as a butcher's shop and still operates a large store in Doncaster. It employs 50 staff.
