In a shallow dish with sides combine the milk, cornstarch, vanilla, and cinnamon. Whisk until everything is combined and the cornstarch is dissolved.
Place one slice of bread into the milk mixture long enough to soak the side then flip the bread and allow it to soak for an additional 3 seconds.
Cook:
Heat a large, nonstick pan over medium heat.
Melt 1 tablespoon butter in the pan and place 2 slices of bread into the center of the pan. Cook for 3 to 4 minutes or until golden brown.
Using a spatula, flip the french toast pieces and brown the other side for an additional 3 to 4 minutes or until golden brown. Remove from the pan and repeat with remaining bread slice and butter.
Enjoy:
Top the french toast with berries, syrup, or your favorite toppings.
Notes
Make sure to soak your white bread long enough for it to absorb the liquid but not so long that it's difficult to flip or lift from the dish.
