A croffle is the perfect blend of a croissant and a waffle, with a crispy outside and a light, flaky inside similar to a croissant. Most croffles will have a caramelized flavor, thanks to the sugar coating that melts and crisps in the waffle iron. Many croffle houses have taken the flavor to a whole new level with the addition of toppings and mix-ins like powdered sugar, bananas, or whipped cream.
