Jenny Bakery Butter Cookies are the company's signature product and the specialty that established the brand's reputation in Hong Kong. First introduced in 2005, the cookies are made fresh daily using simple ingredients and traditional production methods, with many stages of the process still carried out by hand to preserve their characteristic quality and texture. They are known for their rich buttery flavor and delicate melt-in-the-mouth consistency, which has become the defining feature of the product. The cookies are available in several varieties, including the original butter flavor, coffee, chocolate, shortbread, and raisin oat, and are commonly sold in assorted tins featuring multiple flavors. They contain no preservatives, artificial colouring, or genetically modified ingredients, reflecting the company's emphasis on straightforward recipes and fresh production. Jenny Bakery Butter Cookies are packaged in the brand's distinctive teddy bear tins, which have become an iconic part of their identity and a recognizable gourmet souvenir from Hong Kong.
