Preheat the oven: Set your oven to 425°F (220°C). Grease a 9-inch square baking dish or a cast-iron skillet.
Mix the dry ingredients: In a large bowl, whisk together the cornmeal, flour, sugar, baking powder, and salt.
Combine the wet ingredients: In a separate bowl, beat the eggs, then stir in the milk and melted butter.
Combine both mixtures: Pour the wet ingredients into the dry ingredients. Stir until just combined; the batter should be lumpy.
Bake: Pour the batter into your prepared dish and bake for 20-25 minutes, or until the top is golden brown, and a toothpick inserted in the center comes out clean.
Serve: Allow the cornbread to cool slightly before cutting into squares. Enjoy warm with butter, honey, or as a side to your favorite meal!
Optional add-ins: For extra flavor, consider adding 1/2 cup of shredded cheese, chopped jalapeños, or a handful of corn kernels to the batter before baking.
Rest before serving: Once your cornbread is baked, let it rest in the pan for 5-10 minutes. This will help it set and make it easier to slice without falling apart.
