In a large mixing bowl, combine the melted butter with both granulated and brown sugars until well incorporated. Add eggs and stir until thoroughly combined.

In a separate small bowl, stir together the buttermilk and baking soda until combined. Pour this mixture into the butter-sugar mixture and stir well.

Add the cornmeal, flour, and salt to the bowl. Stir just until combined. Be careful not to overmix - the batter doesn't need to be completely smooth.

Pour the batter into the prepared baking pan. Bake for 22-30 minutes, or until a toothpick inserted in the center comes out clean.
