Brush cast-iron corn stick pans lightly with a small amount of melted butter, and set aside.
Combine cornmeal and flour in a small mixing bowl; mix well. Add buttermilk and egg, stirring just until dry ingredients are moistened. Stir remaining butter into batter, mixing well.
Heat prepared pans in a 400° oven 3 minutes or until very hot. Spoon batter into pans, filling two-thirds full. Bake at 400° for 20 minutes or until lightly browned. Remove corn sticks from pans immediately, and serve hot.
