Mix the Batter: In a large mixing bowl, combine cornmeal, eggs, cream-style corn, grated cheese, chives or onion tops, salt, baking powder, baking soda, oil, and milk. Mix until just combined.
Bake: Pour the mixture into a greased 13×9-inch baking pan. Spread evenly. Bake in a preheated 400°F (200°C) oven for 35–40 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean.
Cool & Serve: Let cool slightly before slicing. Serve warm on its own or with a drizzle of hot sauce or a side salad.
Notes
