Sopaipillas are little pillows of bliss. They are similar to fry bread that puffs up when fried until golden brown on the outside and remains soft on the inside. Sopapilla dough is also unsweetened, which means it can be used for either sweet or savory applications. Buñuelos, on the other hand, are rolled out thin and fried until crispy. They are also always served as a dessert.
