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 and toss gently to coat evenly. Allow to soak for 2–3 minutes so bread absorbs the liquid.
03 - Combine 1/4 cup sugar and 1 teaspoon cinnamon in a small bowl, mixing thoroughly until uniform.
04 - Melt 1 tablespoon butter in a large nonstick skillet over medium heat, swirling to coat the bottom evenly.
05 - Transfer soaked bread cubes to the skillet using a slotted spoon, arranging in a single layer. Cook for 2–3 minutes per side, turning frequently until all sides are golden brown and crispy. Cook remaining batches with additional butter as needed.
06 - Immediately transfer cooked bites to the cinnamon sugar mixture and toss to coat thoroughly while still warm.
07 - Whisk powdered sugar, milk, and vanilla extract in a small bowl until smooth and drizzle-consistency.
08 - Drizzle glaze over warm French toast bites and serve immediately for best texture and flavor.
