Insert a wooden skewer into each hot dog, then wrap a slice of cheese around it.
In a mixing bowl, whisk together the flour, sugar, baking powder, and salt.Add the egg and milk, stirring until a thick, smooth batter forms.
Pour the breadcrumbs into a deep dish or bowl.
Transfer the batter into a tall glass for easy dipping.
Dip each hot dog and cheese skewer into the batter, ensuring full coverage, then roll it in panko breadcrumbs until evenly coated.
Heat vegetable oil in a deep pan to 350°F (180°C).
Fry the corn dogs in small batches, turning occasionally, for 3-5 minutes or until golden brown and crispy.
Place the fried corn dogs on paper towels to absorb excess oil.
For an authentic Korean-style touch, sprinkle with sugar.
Enjoy them hot with ketchup, mustard, or your favorite dipping sauce!
