There are four types of waffles. Belgian, American, Brussels, and Liege.   Belgian waffles were not created in Belgium but in America. The waffle batter is made with baking powder instead of yeast. It's thicker than traditional American waffles, which helps create a light and airy texture with a crispy exterior.   American waffles are made similarly to Belgian waffles with baking powder, which creates a thin and dense waffle.   Brussels waffles are rectangular and made from beaten egg whites or yeast to add height and their signature fluffy texture. It's typically served as a dessert waffle topped with whipped cream, fresh fruit, chocolate sauce, and chopped nuts.   Liege waffles are made with yeast and pearl sugar, which caramelizes when cooked, giving the waffles a crispy exterior. The yeast creates a denser waffle that won't get soggy when drizzled with syrup or other toppings.
