In a large mixing bowl, stir together the all-purpose flour, cornmeal, brown sugar, baking soda, and salt.
In another bowl, beat eggs; stir in buttermilk, and melted butter. Add all at once to dry ingredients. Stir just until moistened (batter will be stiff).
Spread batter in prepared pan. Bake in a 350 degree F oven for 30 to 35 minutes or until top is a deep golden brown. Serve warm. Makes 10 servings.
