Preheat your oven to 350°F (175°C).
In a large mixing bowl, combine the thawed corn, softened cream cheese, cheddar cheese, sour cream, and mayonnaise.
Add garlic powder, chili powder, cumin, cilantro, and salt and pepper to the bowl, mixing until well incorporated.
Transfer the mixture into a baking dish, spreading it evenly.
Bake in the preheated oven for about 25-30 minutes, or until the dip is bubbling and golden on top.
Once baked, remove the dip from the oven and allow it to cool slightly before serving with tortilla chips or vegetables.
