Preheat the air fryer: Set your air fryer to 350°F (175°C) while you prep. A warm basket helps crisp the wrappers.
Make the egg wash: Whisk 1 egg with 1 tablespoon of water in a small bowl.
If avoiding eggs, use water or a milk alternative.
Lay out the wrappers: Place several wonton wrappers on a clean, dry surface. Keep the rest covered with a slightly damp towel so they don’t dry out.
Add the filling: Spoon about 1 to 1½ teaspoons of Nutella into the center of each wrapper. Don’t overfill or they’ll burst.
Add extras (optional): A thin slice of strawberry or banana on top of the Nutella is delicious.
Keep add-ins minimal so the wrapper seals.
Seal the wontons: Brush the egg wash lightly along the edges. Fold into a triangle by bringing one corner to the opposite corner, pressing out air pockets as you seal. Press firmly along the edges.
Double-seal for safety: For extra insurance against leaks, crimp gently with a fork or fold the two side corners inward and press again.
Oil lightly: Spray both sides of the wontons with oil.
Don’t soak them—just a light, even coating for crisping.
Air fry: Arrange wontons in a single layer in the basket, leaving space between them. Cook 4–6 minutes, flipping halfway, until golden and crisp. Work in batches if needed.
Cool briefly: Let them sit 1–2 minutes.
The filling will be lava-hot right out of the fryer.
Finish and serve: Dust with powdered sugar, add a drizzle of melted chocolate, or serve with a scoop of vanilla ice cream. Enjoy warm.
