Directions
Beat the egg to blend. Brush the edges of the Wonton sheet with egg. Place 1 tablespoon of Nutella into the center of the Wonton sheet. Fold the sheet diagonally in half over the filling and press the edges of the wrapper to seal.
Add oil to a large frying pan. Heat the oil over medium heat. Add the Nutella-filled Wontons to the hot oil and cook until they are golden brown, about 45 seconds per side. Using a slotted spoon, transfer to a plate lined with paper towels to drain. Dust with powdered sugar.
