In a medium bowl, whisk together eggs, powdered sugar, milk, maple syrup, and ground cinnamon until smooth.

Cut each slice of bread into thirds to form sticks.

Dip each bread stick into the egg mixture, coating all sides.

In a shallow plate, mix granulated sugar and cinnamon until combined.

Heat a large skillet over medium heat and coat with nonstick spray.

Cook the bread sticks in batches, turning to brown all sides evenly.

Remove from skillet and immediately roll in cinnamon sugar until fully coated.

Serve Homemade French Toast Sticks warm.
