In a medium bowl, combine the softened cream cheese, lump crab meat, soy sauce, sesame oil, Worcestershire sauce, garlic powder, onion powder, sliced green onion, sugar, and ground black pepper. Mix until the filling is smooth and well blended.
Lay out the wonton wrappers on a clean, dry surface. Spoon about 1 heaping tablespoon of the filling into the center of each wrapper. Dip your fingers in water and wet all four edges of the wrapper.
Fold up two opposite corners of the wrapper to meet in the center, then fold up the remaining two corners to create a pouch. Press the seams firmly to ensure they’re well sealed. Repeat with the remaining wrappers and filling.
Preheat your air fryer to 350°F (175°C). Lightly spray the air fryer basket or metal insert with nonstick cooking spray.
Arrange the wontons in a single layer in the basket, being careful not to overcrowd them. Lightly spray the tops of the wontons with nonstick spray. Cook for 7-8 minutes, or until they’re golden brown and crispy.
Remove the crab rangoons carefully using tongs or a spatula. Let them cool slightly before serving with your favorite dipping sauce.
