Speculoos biscuits with their characteristic dark brown colour


Speculoos is a traditional biscuit that has gained immense popularity worldwide under the brand Lotus Biscoff, as a biscuit, a spread, and through cross-branding.

However, many people associate speculoos biscuits only with Lotus Biscoff, and that's a mistake!

There is much more to discover about this biscuit with its unique blend of caramelic and warm spice notes that make it really special.

In this blog post, we will deep dive into the world of speculoos and speculaas biscuits, exploring their origins, ingredients, and, most importantly, their flavour profile and potential pairings.

For Food & Beverage start-ups and SMEs founders, understanding the true flavours of Speculoos and Speculaas can enhance your product development (new or existing product development) and help you craft a unique flavour profile for your own products.



What is Speculoos/Speculaas?

Traditional Speculaas wooden mould from the Netherlands to shape the biscuits as windmills

I can't talk about speculoos without explaining its origin and how it started with another biscuit: speculaas.

Speculaas, originated from Belgium and the Netherlands, is a traditional biscuit made with caramelised sugar and a variety of spices, with a characteristic dark brown colour.

Each baker used to have their own special blend of spices, which typically consisted of cinnamon, nutmeg, clove, aniseed, white pepper, coriander, and sometimes ginger, cardamom, and mace.

Traditionally, speculaas are shaped using wooden carved moulds, giving them their distinctive designs. One of the most popular shapes in the Netherlands is of course a windmill, which is why they are often referred to as Dutch Windmill Cookies.

While speculaas cookies are enjoyed throughout the year in many regions, they hold a special significance in Belgium, the Netherlands, and Germany during the winter period, especially during the feast of Saint Nicholas and Christmas.

It is during this time that the speculaas cookies are often shaped in the form of the bishop Saint Nicholas.

A French bakery in Brussels was the first to introduce the word Speculoos, which is a translation of the word speculaas. As a result, Speculaas and Speculoos are synonymous in most regions of Belgium.

Decades later, the Belgian bakery Lotus, launched its own version of speculoos biscuits. They transformed the traditional recipe by using a smaller amount of cinnamon and more butter.

This resulted in a lighter spice flavour, a more caramel-like taste, and a softer texture compared to traditional speculoos/speculaas biscuits.

Originally individually wrapped and served with coffee in restaurants, the speculoos biscuit was renamed Biscoff, a combination of the words 'biscuit' and 'coffee'.

Today, when people refer to speculoos, they are usually referring to the Lotus Biscoff. However, it is important to note that this is not the same as the traditional speculoos or speculaas biscuit.



Speculoos/Speculaas Flavour profile

The difference between windmill cookies from the Netherlands and their unique blend of spices and the classic Lotus Biscoff with its hint of cinnamon.

For me, both Lotus Biscoff and the French equivalent from LU had a caramelic flavour with medium to strong burnt sugar notes. In particular, the Lotus Biscoff had a more prominent cinnamon undertone along with woody and herbal notes. Overall, they tasted like candy floss to me.

Most of the speculaas I have tried had caramelic and molasses notes, a strong blend of spices, mainly cinnamon, ginger, nutmeg, clove, cardamom, and coriander seeds, as well as subtle citrus undertones. The spice blend was definitely more pronounced compared to Lotus Biscoff.
