Preheat your mini waffle iron for about 5 minutes or until hot. Many have an indicator light that goes off when the iron is ready.
Stir together all of the chaffle ingredients.
Lightly grease both cooking surfaces of the waffle maker with non-aerosol oil (see notes below). Then, add half of the batter to the waffle maker and close the lid.
Cook for 3 minutes, or until nicely browned. Do not open while there is a lot of steam coming from the waffle maker, as this indicates that it is not done.
Carefully remove and allow to cool for 5 to 10 minutes to firm up. Repeat with the remaining batter.
For crispy, hot waffles, toast in a toaster just before serving.
Notes
I have a non-stick Dash mini waffle maker and I have had success not greasing my waffle maker when making chaffles. However, to ensure that the batter does not stick, I do recommend that you spray the waffle maker with non-aerosol cooking oil, as aerosol can make the iron sticky and hard to clean. To make a non-aerosol cooking oil, simply add some oil to a spray bottle and lightly spray both cooking surfaces of the waffle maker.
Do not try to cook all the batter at once, trust me, I've tried! It will ooze out all over the place, not cook through, and make a giant mess!
