In another bowl, mix the milk, egg, and melted butter.

Pour the wet ingredients into the dry ingredients and stir until combined.

Heat a pan over medium heat and lightly grease it with butter.

Pour 1/4 cup of batter for each pancake onto the pan.

Cook until bubbles form on the surface, then flip and cook until golden brown.
