Ingredients

5 tablespoons unsalted butter, plus more for the pan

3/4 cup all-purpose flour

3/4 cup yellow cornmeal

1 1/2 teaspoons baking powder

1/2 teaspoon baking soda

1/2 teaspoon kosher salt

1 cup buttermilk (shake before measuring)

2 large eggs

Preparation

Preheat oven to 425°F and position a rack in the middle. Butter an 8-inch-square baking pan.

Melt the butter in the microwave in a microwave-safe dish in three 15-second intervals on high or in a small pan on the stove. Set it aside to cool.

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

In a large bowl, whisk together the buttermilk and eggs. Add the melted butter. Add the flour-cornmeal mixture and stir just until combined. Pour the batter into the pan. Bake until the cornbread just begins to brown and a toothpick inserted into the center comes out clean, 18 to 23 minutes. Cool for about 10 minutes before serving.
