Preheat griddle or large skillet (if electric) to 375°F Grease lightly with oil. Griddle is ready when small drops of water sizzle and disappear almost immediately.
Mix dry ingredients together; add egg, buttermilk and butter, beating well after each addition.
Pour 1/4 cup batter for each pancake onto hot griddle. Cook 1 to 1-1/2 minutes, turning when edges look cooked and bubbles begin to break on surface. Continue to cook 1 to 1-1/2 minutes or until golden brown.
