Preheat and prepare the skillet: Preheat your oven to 400°F. Place a cast-iron skillet inside as it heats. A hot skillet is key. It creates those crisp, golden edges that make cornbread unforgettable. I learned this trick from a neighbor who insisted that a properly heated pan is non-negotiable.

Mix the dry ingredients: In a large bowl, whisk together the cornmeal, flour, baking powder, salt, Creole seasoning, garlic powder, and onion powder. This blend gives the bread its signature savory warmth.

Combine the wet ingredients: In another bowl, whisk the buttermilk, milk, eggs, and melted butter until smooth. The buttermilk adds tenderness and a subtle tang that balances the sweetness of the corn.

Bring it together: Pour the wet mixture into the dry ingredients and stir gently. Do not overmix. Fold in the corn kernels, diced bell peppers, chopped onion, and shredded cheddar cheese. The batter will be thick and speckled with color.

Bake to golden perfection: Carefully remove the hot skillet from the oven and lightly grease it with butter. Pour the batter into the skillet. You should hear a soft sizzle. Bake for 20–25 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean. Let it cool slightly before slicing. The smell alone will draw everyone into the kitchen.
