The company was formed by Thomas Tunnock as Tunnock's in 1890, when he purchased a baker's shop in Uddingston. The company expanded in the 1950s, and it was at this time that the core products were introduced to the lines. It is currently headed by Lord Douglas, who purchased the firm from Thomas' grandson Boyd for an undisclosed amount in 2013. .
Tea Cakes 
The Tunnock's Tea Cake is a sweet food popular in the United Kingdom and the Isle of Man. They are often served with a cup of tea or coffee.
The product consists of a small round shortbread biscuit covered with a dome of Italian meringue, a whipped egg white concoction similar to marshmallow. This is then encased in a thin layer of milk or dark chocolate and wrapped in a red and silver foil paper for the more popular milk chocolate variety, with blue, black, and gold wrapping for the dark.
Caramel Wafers 
The Tunnock's Caramel Wafer, correctly known as the Tunnock's Milk Chocolate Coated Caramel Wafer Biscuit, is a bar consisting of five layers of wafer, interspersed with 4 layers of caramel. The bar is coated in chocolate, made from condensed milk. The wafers are wrapped in red and gold coloured foil. Dark chocolate wafers, wrapped blue and gold, are also available.
An individual wafer is devoid of a sell-by date, though the multipacks do have one. In many small outlets they are available separately. The wrappers of the milk chocolate version bear the wording "more than 5,000,000 of these biscuits made and sold every week".
Other products 
The other products in Tunnock's lines are largely based on the core products. The Caramel Log is similar to the Caramel Wafer, but with the addition of roasted coconut to the outside of the bar. Wafer Creams and Florida Orange have chocolate and orange flavoured cream in place of the caramel.
A Snowball is similar to the Tea Cake, with the addition of grated coconut to the exterior of a soft chocolate shell but with no biscuit base.

The face of the Tunnock's Boy appears on nearly all Tunnock's products.
Factory tours have become so popular that the firm keeps a year-long waiting list to manage demand.
