Preheat oven to 375 degrees F. Generously butter a 15x10x1-inch baking pan; set aside. In a medium bowl combine eggs, buttermilk, and melted butter. In a large bowl combine the flour, sugar, baking powder, baking soda, and salt. Make a well in the center of the flour mixture. Add buttermilk mixture; stir just until combined (do not overbeat).
Pour batter into prepared pan, spreading evenly. Immediately place in oven. Bake 12 to 15 minutes or until set and lightly browned.
