Step 1

Preheat the oven to 425°F and place a rack in the middle. Place a 10 inch cast-iron pan, a small pie pan, or an 8x8 square baking dish in the oven to preheat with the pan.

Step 2

While the oven is preheating, melt the butter in the microwave or in a small pan on the stove. Set it aside to cool.

Step 3

In a bowl, whisk together the flour, cornmeal, baking powder, baking soda, and salt.

Step 4

In a large bowl, whisk together the buttermilk and the eggs. Add the melted butter.

Step 5

Add the flour-cornmeal mixture and stir just until combined.

Step 6

Pour the batter into the pan. Bake until the cornbread begins to brown, especially around the edges. A toothpick inserted in the center should come out clean - about 18 - 24 minutes. Cool for about 10 minutes before serving.
