In the UK we eat pancakes (crêpes) once a year (for some reason). It takes me no more than five minutes to make the batter from scratch. I do it the night before so it's ready to go, but you don't have to. I use one bowl. I imagine if you did it more frequently you'd become even more efficient than I am.

I do make crêpes from scratch, on the rare occasion I make them. They’re simpler than buttermilk pancakes, with fewer ingredients, and it is a one-bowl operation.
