In a mixing bowl, combine 1/2 cup whole milk, 4 large eggs, 2 tablespoons melted butter, 1 tablespoon sugar, and 1/2 teaspoon salt. Whisk together until well blended.
Sprinkle in ground cinnamon to taste. Whisk again to incorporate the cinnamon fully into the mixture.
Preheat your waffle maker according to the manufacturer's instructions.
Dip each slice of bread into the custard mixture, ensuring both sides are well-coated.
Lightly grease the waffle maker and place the soaked bread slices in it. Close the lid and cook for about 3-5 minutes.
Carefully remove the Waffled French Toast from the waffle maker and serve immediately topped with maple syrup, whipped cream, and fresh berries.
