1. Preheat oven to 350º. Combine flour and next 4 ingredients in a large bowl. Whisk together buttermilk and eggs. Gradually stir buttermilk mixture into flour mixture. Gently stir in butter. (Do not overmix; batter will be lumpy.)
2. Pour batter into a lightly greased 15- x 10-inch jelly-roll pan. Sprinkle with pecans.
3. Bake at 350º for 25 to 30 minutes or until golden brown and done. Serve immediately with Caramel-Apple Topping.
