Hoddeok is a popular street food of South Korea. I came to know this after watching a television show about Korean food.
They are made with  wheat  flour,  sugar,  water, milk and dry yeast. Though the original recipe calls for sweet rice flour but this was omitted by me.  Allow the dough to  stand in a warm place  for 3 hours. If using active dry yeast, whisk the water, sugar and dry yeast in a small bowl, let  the yeast to activate for about 10 minutes before adding the rest  the ingredients.
After  fermentation, it is shape into ball then stuff with brown sugar and nut filling. Shallow fry these balls then flatten them using spatula until golden brown. They  are best eaten hot.
