First, turn your oven to 400°F (200°C). Let it get nice and hot while you prep. Grease your baking pan with butter or non-stick spray. A hot oven ensures a good rise for the bread.
Mix the Dry Ingredients
In a large bowl, whisk the flour, cornmeal, sugar, and baking powder. Add the salt and stir well. Make sure there are no large clumps of flour. This ensures an even texture later.
Prepare the Wet Ingredients
In a separate medium bowl, whisk the milk and the egg together. Slowly pour in the melted butter while whisking. Ensure the butter is not too hot. You do not want to cook the egg.
Combine the Mixtures
Make a small hole in the center of the dry ingredients. Pour the milk mixture into the dry bowl. Stir gently until just combined. Stop mixing as soon as the flour disappears.
Pour into the Pan
Transfer the thick batter into your prepared baking pan. Use a spatula to spread it evenly to the corners. Smooth the top so it bakes flat. It should look golden and beautiful.
Bake Until Golden
Place the pan on the center rack of the oven. Bake for 20 to 25 minutes. The edges should pull away from the sides. The top should look light golden brown.
The Toothpick Test
Insert a toothpick into the center of the cornbread. If it comes out clean, the bread is done. If it has wet batter, bake for 3 more minutes. Do not overbake it.
Cool and Serve
Let the cornbread sit in the pan for 10 minutes. This helps it set so it does not crumble. Slice it into squares or wedges. Serve it warm with extra butter or honey.
Notes
Honey Butter Topping: Brush the top with honey and butter right after baking. It adds a lovely shine and sweetness.
Add some Heat: Fold in a handful of chopped jalapeños for a spicy kick. This tastes great with chili.
Cheesy Cornbread: Stir in 1/2 cup of shredded cheddar cheese to the batter. It makes the bread very savory.
Don't Overmix: Overmixing develops gluten. This makes the cornbread tough and chewy instead of tender.
Buttermilk Swap: You can use buttermilk instead of regular milk. It adds a nice tang and extra moisture.
