Whisk the first five ingredients together in a large bowl and pour the mixture into a shallow pan, pie plate, or baking dish.
Lay a slice of brioche (or regular bread) into the mixture and soak until the bread is just saturated with the mixture, turning to coat the other side. Repeat for each slice.
Pre-heat waffle iron and grease lightly.
Place one slice of soaked bread in the center of the waffle iron and cover
Cook as if it were a waffle. The cooking time will be about the same as for a waffle.
Serve immediately with syrup, powdered sugar, and/or fruit topping for a different, delicious, and unusual breakfast.
