Mix all the ingredients in a large bowl (with room for expansion) until combined. The mixture will be fairly loose and lumpy.

Cover the bowl with plastic wrap and let rest at room temperature for about 1 hour until the mixture is bubbly on the top. You can go ahead and cook the batter now, or refrigerate the batter overnight.

Preheat oven to 175 degrees F. Line a baking sheet with a cooling rack to keep waffles warm while cooking. Preheat waffle iron.

Spray waffle iron with non stick spray and scoop about 2/3 to 3/4 cup batter into the waffle iron. (My belgium waffle maker took about 3/4 cup) Cook according to manufacturers directions or about 5 minutes and golden brown.
