Start by cutting the crust off each slice of bread.

Using a rolling pin, flatten each slice to make it easier to roll.

Spread 3 teaspoons of Nutella on each slice and then roll it up into a log.

In a small bowl, whisk together the eggs, vanilla extract, and milk.

Dip each roll-up into the egg mixture, ensuring it's well coated.

Spray the air fryer basket with cooking spray and place the roll-ups inside, making sure not to overcrowd them.

Air fry at 375°F for about 6 minutes, or until golden brown, turning the roll-ups halfway through.

Once done, sprinkle with powdered sugar while they're still warm and serve immediately.
