The shortbread is baked in the Moray village of Aberlour, following a recipe developed by Joseph Walker in 1898.

By 1970, the company had expanded to almost 100 employees, 14 vans, and two additional shops in the nearby towns of Elgin and Grantown-on-Spey.

[7] The company started producing oaten biscuits for Duchy Originals in 1992, having been approached the previous year.

[8] The profits of Walker's Shortbread, which is also still owned and managed by the Walker family,[9] were diminished by a global increase in the price of butter in 2018 by around 50%[10] due to supply shortages and demand increases, resulting in the company seeing a 60% drop in operating profit.

[1] The company rebranded, in 2020, changing its name to Walker's Shortbread Ltd.[12] It announced it was exploring how to create a vegan version of the butter-based biscuit in 2024.
