In a large bowl, whisk together the rice flours, baking powder, sugar, cinnamon, and salt. Make a well in the middle of the mixture.
In a medium bowl, whisk together the eggs, oil, coconut milk, and vanilla.
Add the wet mixture the well of your dry ingredients, and fold until combined. If the mixture is too thick, stir in the milk beverage as needed to get a thick but pourable consistency.
Cook according to your waffle maker's directions.
Eat now, or if you wish to freeze, place them on paper towels (while you eat the other ones) to absorb any excess moisture while cooling.
It is best to freeze them with wax paper separating each, but not totally necessary. Pop in the toaster or microwave for a quick breakfast.
