Liège waffles are one of the two most popular waffle varieties in Belgium. These unevenly shaped, chewy treats are made with a thick, brioche-like dough which is sweetened with pearl sugar and baked in a specially-designed waffle pan. During the baking process, the pearl sugar melts and gives the waffles a unique caramel flavor.

Although the origin of Liège waffles is somewhat vague, it is believed they were influenced by French culinary traditions and made famous by the skillful Liège bakers. In Liège, these waffles are usually enjoyed plain, but they can also be topped with powdered sugar, whipped cream, chocolate, or various fruits.
