01 - Whisk together eggs, milk, sugar, vanilla, cinnamon, and salt in a medium bowl until thoroughly combined.
02 - Add bread cubes to the egg mixture, toss gently to coat evenly, and let soak for 2–3 minutes to absorb the liquid.
03 - Combine 1/4 cup sugar and 1 teaspoon cinnamon in a small bowl, mixing until evenly blended.
04 - Melt 1 tablespoon butter in a large nonstick skillet over medium heat, ensuring the surface is evenly coated.
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 until all sides are golden brown. Repeat with remaining butter and bread cubes as needed.
06 - Immediately toss the hot cooked bites in the cinnamon sugar mixture while still warm, ensuring even coating on all sides.
07 - Whisk powdered sugar, milk, and vanilla in a small bowl until completely smooth and lump-free.
08 - Drizzle the prepared glaze over warm French toast bites and serve immediately while hot.
