01 - Cut each bread slice into 3 or 4 sticks, depending on thickness. Use slightly stale bread for best texture to prevent sogginess.
02 - In a shallow bowl, whisk together eggs, milk, vanilla extract, 2 tablespoons sugar, 1/2 teaspoon cinnamon, and a pinch of salt until well combined.
03 - In a separate bowl, mix 1/3 cup sugar with 1 tablespoon ground cinnamon until evenly blended. Set aside for coating.
04 - Heat 1 tablespoon butter in a large nonstick skillet over medium heat until melted and evenly coating the pan surface.
05 - Dip bread sticks quickly into the egg mixture, ensuring all sides are coated but not saturated. Work in batches to avoid overcrowding.
06 - Place coated sticks in the skillet and cook on all sides until golden brown, about 2-3 minutes per side. Add remaining butter as needed between batches.
07 - Immediately toss hot French toast sticks in the cinnamon sugar mixture to coat evenly while still warm for maximum adherence.
08 - Serve warm with maple syrup for dipping. Best enjoyed immediately while crispy.
