01 - Whisk together eggs, milk, sugar, vanilla, cinnamon, and salt in a medium bowl until well combined.
02 - Add bread cubes to the egg mixture and toss gently to coat. Let soak for 2–3 minutes to absorb the liquid.
03 - Mix together 1/4 cup sugar and 1 teaspoon cinnamon in a small bowl for the coating.
04 - Heat 1 tablespoon butter in a large nonstick skillet over medium heat until melted and bubbling.
05 - Using a slotted spoon, transfer soaked bread cubes to the skillet in a single layer. Cook for 2–3 minutes per side, turning until all sides are golden brown. Repeat with remaining butter and bread cubes as needed.
06 - Immediately toss the cooked bites in the cinnamon sugar mixture while hot to ensure coating adheres.
07 - Whisk powdered sugar, milk, and vanilla in a small bowl until smooth and drizzle-ready.
08 - Drizzle glaze over warm French toast bites and serve immediately.
