In a mixing bowl, combine minced shrimp with cream cheese, soy sauce, green onions, cilantro, garlic, ginger, cornstarch, black pepper, salt, red pepper flakes, and egg if needed. The mixture should be sticky and easy to shape.

Shape the shrimp mixture into small balls using about 1 to 2 tablespoons of filling each.

Coat each ball in egg roll wrappers, pressing tightly to ensure they adhere well.

Heat oil in a deep pan until it reaches 350°F.

Fry the shrimp balls until they're beautifully golden brown and cooked in the center. Make sure the heat isn't too high, or the outside will brown before the center cooks.

Transfer the fried shrimp balls to a wire rack to drain any excess oil, then serve with sweet chili dipping sauce!
