In a large bowl, combine the cream cheese, crab meat, green onion, sugar, garlic powder, and soy sauce in a bowl. Mix well.
8 ounces cream cheese, 6 ounces crab meat, 1 green onion, 1 tablespoon powdered sugar, ½ teaspoon garlic powder, ¼ teaspoon soy sauce
Working quickly, spoon 1 tablespoon of the filling in the middle of a wonton wrapper. Dab a bit of water on the outer edges of the wrapper and fold two opposite ends together.
20 wonton wrappers
Fold the other two ends to create a small parcel, pinching the edges together to seal the wonton tightly. Repeat with remaining filling and wrappers.
Meanwhile, heat 3 inches of cooking oil in a pot to 350°F. Fry a single layer of wontons at a time for 2-3 minutes, turning as needed, until evenly golden brown.
Oil
Remove wontons from the oil with a strainer or slotted spoon, transferring the fried wontons to a paper-towel lined plate to drain. Repeat with remaining wontons, then serve with sweet and sour sauce or sweet chili sauce.
Sauce for dipping: Sweet and sour sauce or sweet chili sauce
