the best judge of how much to use, but go ahead and start with half a cup and see how that goes. even on the highest setting, i found that these waffles still needed a little extra time to cook. if the top and the bottom of the waffle started to separate as i very slowly tried to pull the waffle maker lid up, i closed it back up and let them cook a little more, and then i had no problem and no mess.
enjoy with some maple syrup and earth balance soy free buttery spread!
