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. Gently toss to coat evenly. Allow to soak for 2-3 minutes, turning occasionally to ensure all pieces absorb the liquid.
03 - Combine 1/4 cup granulated sugar and 1 teaspoon ground cinnamon in a small bowl. Stir until uniformly blended.
04 - Melt 1 tablespoon butter in a large nonstick skillet over medium heat, swirling to coat the bottom evenly.
05 - Using a slotted spoon, transfer soaked bread cubes to the hot skillet in a single layer. Cook for 2-3 minutes per side, turning until all sides are golden brown and crispy. Work in batches, adding remaining butter as needed.
06 - Immediately transfer cooked bites to the cinnamon sugar mixture. Toss gently while still warm to coat evenly on all sides.
07 - Whisk powdered sugar, milk, and vanilla extract in a small bowl until completely smooth and pourable.
08 - Arrange glazed French toast bites on a serving platter. Drizzle with vanilla glaze and serve immediately while warm.
