Whisk together flour, baking powder, salt and white sugar. Make a well in the middle and add eggs and milk. Whisk until well combined and no longer lumpy. Batter should be very thick. Transfer batter into a drinking glass for easier coating. Chill until ready to use.
Lightly dust CDO Idol Cheesedogs in some flour. Skewer each with a barbecue stick. Heat up oil. Place panko breadcrumbs in a tray or large plate.
Dip each skewer into the batter until well coated. Let excess drip then coat with panko breadcrumbs. Repeat for all CDO Idol Cheesedogs.
Deep-fry corndogs for 3-5 minutes or until golden brown in all sides. Turn from time to time to ensure even browning.
Once cooked, transfer to a cooling rack or paper towel line plate and sprinkle immediately with white sugar. Make sure all sides are lightly coated.
Optional: Enjoy with mustard and ketchup. You may also dust with colored sugar instead for even more unique corn dogs.
