Preheat griddle to 375° F. In a bowl, mix flour, baking soda, baking powder, sugar and salt. In a small bowl, whisk eggs, buttermilk and butter until blended. Stir egg mixture into flour mixture; mix with a whisk until batter is smooth.  Pour 1/3 C. batter onto lightly-greased hot griddle. Flip pancakes after bubbles appear in batter and edges appear dry. Pancakes are done when brown on both sides. Serve with butter and warm syrup. Recipe featured in Brickyard to Backyard Cookbook, submitted by Colleen Dallenbach of Indianapolis, Indiana.
