In a large mixing bowl, combine the ground beef, cheddar cheese, blue cheese, crumbled bacon, breadcrumbs, diced onion, diced pickles, salt, and pepper. Mix until well combined.

Divide the mixture into eight equal portions and shape each around a hot dog to form a corn dog.

Place a slice of American cheese on top of each shaped corn dog and secure it with a wooden skewer.

In another bowl, blend the cornmeal, flour, sugar, baking powder, and salt together until mixed well.

In a separate bowl, whisk the egg and milk together until smooth.

Dip each corn dog in the egg mixture, then roll in the cornmeal mixture to coat evenly.

Heat oil in a deep fryer or a large pot to 350°F (175°C).

Fry the corn dogs in batches for 3-4 minutes or until golden brown and fully cooked.

Remove from oil and place on paper towels to drain excess oil.

Serve hot with your favorite dips like ketchup, mustard, or ranch dressing.
