Yes! Crepe batter is unique and unlike other batters, it is supposed to be very thin. It should be much more runny than pancake batter. This helps the crepes to come out light and fluffy after they cook, rather than thick and dense. The consistency should be slightly thinner than heavy cream. If your batter is too thick, you can thin it out by adding a tablespoon of milk at a time until it is the right consistency.
