Prepare the Croissants: Preheat the air fryer to 350°F (175°C). Cut each croissant in half lengthwise, creating a "pocket" for the filling.
Spread Nutella: Gently spread a generous layer of Nutella inside each croissant half.
Add Chocolate Chips: Sprinkle mini chocolate chips into the Nutella spread, ensuring an even distribution.
Assemble the Croissants: Place the filled croissants back together (top part over the Nutella and chocolate filling). Lightly press the edges to seal.
Brush with Butter: Brush the tops of the croissants with melted butter to help them crisp up and develop a golden color.
Air Fry: Place the croissants in the air fryer basket, making sure they’re not overcrowded. Air fry at 350°F (175°C) for 5-7 minutes or until golden and crispy.
Serve: Remove from the air fryer and let cool for a minute. Optionally, dust with powdered sugar for an extra touch of sweetness. Serve warm and enjoy!
