In a large bowl, stir together
flour, baking powder, baking soda, sugar, and salt; set
aside. In a small bowl, beat eggs; add yogurt and mix
well. Stir in buttermilk and melted butter. Pour liquid
ingredients into dry ingredients all at once and whisk
just until moistened. Heat griddle and 2 Tbsp. butter
over medium heat (300 degrees for electric griddle). Pour
1/4 cup batter into griddle for each pancake. Cook 2 to
3 min. until underside is golden, then flip. Cook 3 to
4 min. more, until center springs back when gently pressed.
Use additional butter, if necessary to prepare remaining
batter. Makes 24 pancakes.
