Step 3
Fill a pastry bag fitted with a 1/4-inch plain round tip with batter; twist end of the bag, and secure with a rubber band. Working in batches, pipe heart shapes, drawing V of batter in the center of hearts to fill, on heated griddle. When pancakes have bubbles on top and are slightly dry around the edges, about 2 minutes, flip over. Cook until golden on the bottom, about 1 minute.
