much more pertinent question:
what are you doing while the "thing" you use to cook the pancakes is heating up?
I use a scale. I can measure out flour, re-tare, sugar, re-tare, baking powder. change bowl, re-tare, milk, egg, beat, add vanilla/almond.
combine and blend wet and dry ingredients like way long before my electric griddle is hot enough to do pancakes. and if I'm cooking bacon to accompany, like way triple/quadruple in the time it takes to combine the ingredients.
a rapid heating frying pan accommodating one pancake at a time is about the only way to beat the "make the mix" routine.
there has to be some other issues in play, because the time to make a pancake batter is not a limiting factor.
