Melt butter & take out egg and place in counter, set aside. Combine the flour, sugar, baking powder, baking soda and salt in a large-sized bowl. Make a well in the center.
Add the milk, vanilla & egg to the slightly cooled melted butter, use a wire whisk to mix. Pour half the wet better into your well.

Let batter rest while you heat a pan or griddle to medium heat. Place some butter in the pan. When it’s ready take a 1/3 or 1/4 cup and fill with batter in pan. Once pancakes start bubbling, it is time to flip. Cook a few more minutes until done, repeat until all pancakes are made, I added new butter each batch.
