Belgian waffles or Brussels Waffles are light, crispy, rectangle waffles made without yeast. On the other hand, Liege waffles are small round waffles made from a yeasted dough filled with clumps of sugar. They are heavy, packed, and dense, like brioche dough cooked on a waffle iron. Their name might seem confusing because Liege is a city in Belgium and so technically, Liege waffles are Belgian.
