This recipe (originally from Aretha Frankenstein's restaurant in Chattanooga, TN) is the ideal I-just-woke-up-from-a-waffle-dream waffle, a morning-of alternative to the overnight yeasted kind. The cornstarch in the batter helps tamp down gluten formation, making these waffles silky and moist inside with a crust as thin and crisp as an eggshell. —Genius Recipes
In a medium bowl, combine the flour, cornstarch, baking powder, baking soda, and salt; mix well. Add the milk, vegetable oil, egg, sugar and vanilla and mix well. Let the batter sit for 30 minutes.
Heat a waffle iron. Follow the directions on your waffle iron to cook the waffles. Serve immediately with butter and pure maple syrup or hold in a 200 degree oven, directly on the rack (don't stack them or they'll get soggy). These also reheat very well in the toaster.
