01 - Thread a half sausage followed by a mozzarella stick onto each wooden skewer, ensuring adequate handle at one end.
02 - In a medium mixing bowl, combine flour, sugar, baking powder, and salt. Add egg and milk, then whisk until the mixture is smooth and thick.
03 - Place panko breadcrumbs and cornmeal or extra flour (if using) in separate shallow bowls for coating.
04 - Pour vegetable oil into a deep pot or fryer to a depth of at least 2 inches. Heat oil to 350°F.
05 - Dip each skewered sausage and cheese into the batter, turning to coat evenly. Roll immediately in panko and cornmeal if desired, gently pressing to ensure coating adheres.
06 - Working in batches, fry 2–3 corn dogs at a time for 3–4 minutes, turning as needed until golden brown and crisp. Remove with tongs and drain excess oil on paper towels.
07 - Optional: Dust hot corn dogs with sugar, then drizzle with ketchup and mustard. Serve immediately for best texture and cheese stretch.
