Combine flour, sugar, baking powder, baking soda, and salt in a large bowl. Mix together then make a well in the center and add milk, melted butter, vanilla, and egg.
Use beaters to blend together until smooth.
If the consistency is found to be too thick for your liking (doesn't pour from a cup) then add a little bit more milk.
Cook in a non-stick pan until golden brown. You should start to see bubbles on the uncooked side.
