First beat the eggs, milk, and vanilla until light and foamy, approx 3 minute at igh speed of a mixer.
Now stir in butter or oil.
Next you want to whisk the dry ingredients together and gently, but quickly, mix into the egg and milk mixture.
Now you want to let the batter relax while griddle is heating (or overnight in refrig.) The batter will thicken upon resting.
Now you can butter and preheat griddle.
Then you can drop ¼ cupfuls of the batter on the lightly greased griddle.
Let this cook on one side until bubbles begin to form and break (this is the time to add anything like berries, choc. Chips, etc), then you can flip the pancakes and cook the other side until golden (turning only once).
