Combine flour and next four ingredients in large bowl.
Whisk together buttermilk and eggs; gradually add flour mixture. Gently stir in melted butter. (Batter will be lumpy). Pour about 1/4 cup batter for each pancake onto a hot buttered griddle or large skillet. Cook pancakes 3 to 4 minutes or until tops are covered with bubbles and edges look dry and cooked. Turn and cook 3 to 4 minutes or until golden brown. Place pancakes in a single layer on a baking sheet, and keep warm in a 200 degree oven up to 30 minutes. Serve with Buttered Honey Syrup.
