In a mixing bowl, combine the softened cream cheese, sour cream, and half of the shredded cheddar cheese. Mix until smooth.

Add the cooked crawfish tails, Worcestershire sauce, hot sauce, garlic powder, onion powder, salt, and black pepper to the mixture. Stir until well combined.

Transfer the mixture to a skillet and cook over medium heat for about 10 minutes, stirring occasionally, until heated through.

Remove from heat and top with the remaining cheddar cheese and chopped green onions.

Serve warm with crackers or bread.
