Combine cornmeal, flour, sugar, baking powder, and salt in a large mixing bowl, whisking together until no lumps hide in the dry blend. This takes about one minute and prevents the finished batter from developing gritty patches that nobody enjoys biting into.
Whisk milk, eggs, and melted butter in a separate bowl until the mixture looks uniformly combined and smells buttery. Pour the wet ingredients into the dry ingredients and stir until just combined—I stop the second no dry streaks remain, because overmixing develops gluten that makes the coating tough instead of tender.
Fold in shredded cheese and green onions carefully, using a spatula instead of vigorous stirring. This distributes them evenly without breaking down the batter structure, which keeps your easy kids finger food from becoming dense.
Slice each hot dog into four pieces (roughly one-inch chunks), then pat them completely dry with paper towels. Wet surfaces cause the batter to slide off during frying, which I learned the hard way at a particularly chaotic family lunch years ago.
Heat vegetable oil to 350°F in a heavy-bottomed pot or Dutch oven—use a thermometer instead of guessing, because batter burns at 370°F but won't cook through at 325°F. This temperature window feels narrow, but you'll know you're right when a single batter drop sizzles and rises immediately.
Working in batches of 6-8 pieces, dip hot dog chunks into the batter until fully coated, then carefully place them into the hot oil using a slotted spoon. Never crowd the pot because the temperature plummets and you'll end up with soggy corn dog bites family kids recipe instead of the crisp exterior you're after.
Fry for 2-3 minutes until the coating turns light golden brown and sounds hollow when tapped with the spoon. Transfer finished bites to a paper towel-lined plate, where they'll stay warm for at least ten minutes before service.
