We have a heart-shaped waffle maker that makes these extra fun!
Amazon doesn't have the model we own, but
here's a similar one.
Out of maple syrup? Here's Bethany's solution: mix brown sugar and water in desired
consistency. Microwave (cover with a towel so no splatters) for 1 minute and stir again.
This makes 6 batches in our waffle maker (4 heart-shaped waffles each).
