Except you add the cream after beating the eggs and flour in the original recipe. Today's waffle and some pancake batter recipes will call for beating the eggs until light and fluffy, which takes a few minutes in a mixer and could take 15 minutes by hand. Then you typically fold or mix the flour and dairy (milk, cream, or buttermilk) into the eggs, alternating small amounts of each. Then add the clarified butter. That's how I would adapt the recipe to the use of a mixer. Also, I would make sure to use salted butter in this recipe or add a small amount of salt.
