Speculoos (Dutch: [speːkyˈloːs] ⓘ;[1] French: spéculoos [spekylos]; German: Karamellgebäck [kaʁaˈmɛlɡəˌbɛk]) is a biscuit, originally manufactured in Belgium, made from wheat flour, candy syrup (from beet sugar), fat, and sometimes cinnamon.

In October 2020, Lotus Bakeries decided to omit the word "speculoos" from local markets, to harmonise their products with their Biscoff brand.

Workers in the Low Countries traditionally made a sandwich in the morning with butter and speculaas or speculoos biscuits.

[citation needed] By 2007, several Belgian companies began marketing a speculoos paste, now available worldwide under various brands and names: as Speculla, Cookie Butter, and Biscoff Spread.

As a form of spreadable speculoos biscuits, the flavour is caramelized and gingerbread-like, with a colour similar to peanut butter[7] and a consistency ranging from creamy to granular or crunchy.
