Step 1

In a large mixing bowl, whisk together flour, sugar, salt, baking soda and baking powder.

Step 2

In a separate bowl, whisk together the milk, melted butter, egg and vinegar until smooth. Pour milk mixture into the dry ingredients and stir until just combined--you want some lumps at this stage.

Step 3

Heat a non-stick pan over medium heat. Lightly grease the pan with oil and raise the temperature to medium. Use a quarter cup to measure the batter onto the preheated pan. Cook until bubbles start to appear on the exposed surface of the pancake, about 1-2 minutes. Flip pancake and cook for an additional 1-2 minutes or until golden brown on the underside.
