In a large bowl, sift together flour, baking powder, baking soda and salt.

In a small bowl, combine egg and buttermilk. Whisk together until blended. Add to flour mixture, stirring only until smooth. Add the melted butter and sugar, and stir until combined.

Over medium low heat, heat pan or griddle. Lightly grease surface of the pan by brushing with melted butter.

Drop about ¼ cup batter on pan in a 5-inch wide circle. Cook until bubbles begin to form on surface and edges begin to brown.

Gently flip and continue to brown the other side. Repeat with remaining batter.

Serve hot with butter and syrup of choice.
