They are also known as Chamorro jawbreaker cookies due to their historically rock-hard texture.

Guyuria was originally made with flour, coconut milk, and a sugar glaze.

Once enough cookies are formed, a batch is fried, cooled, and finally coated with a sugar glaze.

Other guyuria dough recipes include sugar, baking powder, and eggs.

Guyuria recipes with baking powder and eggs, however, lead to cookies that are too inflated and soft.
