01 - Whisk together eggs, milk, sugar, vanilla, cinnamon, and salt in a medium bowl until fully combined and smooth.
02 - Add bread cubes to the egg mixture, toss gently to coat evenly. Allow to soak for 2–3 minutes, turning occasionally to ensure absorption.
03 - Combine 1/4 cup granulated sugar and 1 teaspoon ground cinnamon in a small bowl. Mix thoroughly until uniform.
04 - Melt 1 tablespoon butter in a large nonstick skillet over medium heat, coating the bottom evenly.
05 - Transfer soaked bread cubes to skillet using a slotted spoon, arranging in a single layer. Cook 2–3 minutes per side, turning until all sides are golden brown and crisp. Repeat with remaining butter and bread cubes in batches.
06 - Immediately transfer cooked bites to the cinnamon sugar mixture while still hot. Toss gently to coat evenly on all sides.
07 - Whisk powdered sugar, milk, and vanilla extract in a small bowl until smooth and drizzling consistency is reached.
08 - Arrange glazed bites on a serving plate. Drizzle prepared glaze generously over warm French toast bites. Serve immediately while hot.
