Preheat the oven to 350˚F
Pour the corn into a large casserole dish. Mix in the mayo, sour cream, chili powder, garlic powder, salt, and half of the queso fresco until combined.
Bake for 30-40 minutes or until heated through and the sides begin to bubble.
Sprinkle the remaining queso fresco over the casserole and top with chopped cilantro. Enjoy!
