Belgian Waffles

These take a little while to make, but they are so worth it!  The
temperature of the mixture cannot be too hot or too cold.  The goal is
to get the yeast to rise.   The aroma of these waffles will awaken your loved ones...yes, like those cheesy coffee commercials in the 80s...but in a much cooler way =)

3 cups warm milk (110 degrees F or 45 degrees C)
3 eggs (separate the yolks and the whites)
3/4 cup butter, melted and cooled to lukewarm
