The kind of waffle that has many spheres is called a "bubble waffle," also known as an egg waffle, eggette, egg puff, puffle, or pancake balls. This waffle is characterized by its unique shape composed of many small, round spheres formed during cooking. It originated in Hong Kong and is a popular street snack there. The batter is traditionally cooked in a special waffle iron that creates these characteristic bubble shapes, making the waffle look like a web of mini spheres or bubble wrap.

This style of waffle is different from regular grid-patterned waffles and tends to be sweeter and more eggy in flavor. It is often served plain or with various toppings like fruits, chocolate, or whipped cream. The bubble waffle is a visually distinctive and delightful twist on the traditional waffle, popular in many parts of the world.
