Belgian waffles are known in the United States as a decadent breakfast item, but in Belgium, they're called gauffres and they're either an indulgent snack or a dessert.
There are two types of gauffres: the Brussels version looks the most like a Belgian waffle sundae that you'd get in the United States -- although the waffle itself is lighter. It's topped with powdered sugar, ice cream, whipped cream -- this is where the idea for a Belgian waffle sundae comes from.
The Liège waffle is denser, chewier and carmelized on the outside with pearl sugar. Liège waffles are meant to be eaten by hand, and come topped with cinnamon sometimes, but never with ice cream or whipped cream.
