Begin by laying out your soft white sandwich or brioche bread slices on a clean surface. Using a rolling pin, gently flatten each slice to about half its thickness, which makes them more pliable and prevents tearing during rolling.

Spread a generous layer of Nutella evenly across each flattened slice of bread, leaving a small border around the edges. If using any optional fillings, sprinkle them evenly over the Nutella. Carefully roll each slice tightly from one end to the other.

In a shallow dish, whisk together the eggs and a pinch of cinnamon until well combined. This egg mixture will coat your Nutella French Toast Roll Ups.

Take each roll-up and quickly dip it into the egg mixture, ensuring to coat all sides but not letting it soak.

Preheat your air fryer to 375°F (190°C). Place the dipped roll-ups in the fryer basket, ensuring they are not overcrowded. Air fry for 8-10 minutes, turning them halfway through.

After cooking, remove the roll-ups from the air fryer and let them cool slightly. Serve warm, drizzled with caramel sauce or dusted with powdered sugar.
