Make Ahead Cinnamon French Toast

RECIPE

To prepare French Toast: Whisk together egg, egg whites, milk, 2 tablespoons sugar, vanilla, 1/4 teaspoon cinnamon and baking powder in a medium bowl until well blended. Place bread slices in a large, shallow baking dish and pour egg mixture over the top; turn to coat evenly. Press a piece of wax paper directly on the bread to cover it, then cover dish with plastic wrap. Refrigerate overnight.
To make cinnamon syrup: Stir together 1/2 cup sugar, corn syrup, 1/4 teaspoon cinnamon and water in a small saucepan. Bring the mixture to a boil over medium high heat, stirring constantly. Boil for 2 minutes. Remove from heat and stir in evaporated milk. Let cool; transfer to a small pitcher.
To cook French Toast: Heat 1 teaspoon oil and 1/2 teaspoon butter in a nonstick skillet over medium high heat. Add four of the soaked bread slices to the pan and cook until golden on both sides, 2 to 3 minutes per side. Transfer the toast to a platter and keep in warm oven. Cook the remaining slices in the same manner, using the remaining 1 teaspoon oil and 1/2 teaspoon butter. Serve with cinnamon syrup.
