Spread 1 to 2 tablespoons of Nutella evenly on half of the bread slices.

Place the remaining bread slices on top to create Nutella sandwiches. Press gently to seal the edges.

Carefully trim the crusts from the Nutella sandwiches.

Cut each sandwich into 3 to 4 strips, creating French toast sticks.

In a shallow bowl, whisk together the eggs, milk, vanilla extract, and ground cinnamon until well combined.

In a separate shallow bowl, mix together the granulated sugar and ground cinnamon to create the cinnamon sugar coating.

Dip each Nutella stuffed French toast stick into the egg mixture, ensuring they’re coated on all sides.

Preheat the air fryer to 350 degrees Fahrenheit (175 degrees Celsius) for about 5 minutes.

Lightly grease the air fryer basket with cooking spray or oil to prevent sticking.

Place the coated Nutella French toast sticks in a single layer in the air fryer basket, leaving some space between each stick. Cook in batches if necessary, depending on the size of the air fryer.

Air fry for 6-8 minutes or until the French toast is golden brown and crispy, turning the sticks halfway through the cooking time.

While the French toast sticks are still hot from the air fryer, roll them in the cinnamon sugar mixture to coat them evenly.

Remove the Air Fryer Nutella French Toast Sticks from the mixture, and let them cool for a minute or two.

Dust with powdered, sugar if desired. Serve hot with maple syrup or fresh fruit for dipping.

Store in an airtight container in the fridge for 2-3 days.
