Preheat your oven to 400°F (200°C) and grease a 9×13-inch baking dish.
In a large mixing bowl, combine the cornbread mix, milk, egg, and melted butter. Stir until well combined.
Fold in the thawed corn, shredded cheddar cheese, hot dog pieces, onion powder, garlic powder, and black pepper.
Pour the mixture into the prepared baking dish, spreading it out evenly.
Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Let the casserole cool for a few minutes before cutting into squares and serving.
Variations & Tips
For a bit of a spicy kick, you could add some chopped jalapeños or a dash of cayenne pepper to the batter. If you’re looking for a vegetarian option, replace the hot dogs with meatless sausage links or some sautéed vegetables like bell peppers and onions. For a touch of sweetness, sprinkle some honey over the top just before serving.
