Start by placing softened cream cheese in a small mixing bowl. Add chopped green onions, garlic powder, and salt. Beat until creamy and fully combined, ensuring every bite is flavorful.
Lay a wonton wrapper on a clean surface. Moisten the edges with water, then spoon about a teaspoon of filling into the center. Fold the corners to form a small star shape or triangle, pressing the edges to seal tightly.
Spray the air fryer basket with a light coat of oil. Place the wontons in a single layer, leaving space between each one. Lightly mist the tops with oil, then air fry at 370°F for 8–10 minutes, until golden and crispy.
