Preheat your oven to 350°F and lightly grease a 2-quart baking dish.
In a large bowl, beat together the softened cream cheese, mayonnaise, and sour cream until smooth and well combined.
Fold in the crab meat, green onions, garlic, Worcestershire sauce, soy sauce, sugar, white pepper, and half of the mozzarella cheese. Mix gently to avoid breaking up the crab too much.
Transfer the mixture to the prepared baking dish and spread evenly. Top with the remaining mozzarella cheese.
Bake for 25-30 minutes until the dip is hot, bubbly, and the cheese on top is melted and lightly golden.
Allow to cool for 5 minutes, then serve warm with wonton chips, crackers, or toasted baguette slices.
