01 - Cut each bread slice into 3 or 4 sticks, depending on thickness.
02 - Whisk together eggs, milk, vanilla extract, 2 tablespoons sugar, 1/2 teaspoon cinnamon, and a pinch of salt in a shallow bowl until fully combined.
03 - Mix 1/3 cup sugar with 1 tablespoon ground cinnamon in a separate bowl. Set aside for coating.
04 - Heat 1 tablespoon butter in a large nonstick skillet over medium heat until melted and bubbly.
