Preheat your oven to 350 degrees. Spray your pan or casserole with a non-stick spray and put aside.
Take a large bowl, add the frozen corn, sour cream, mayo, garlic powder, salt, 1 ½ teaspoon chili powder and 4 ounces crumbled Queso Fresco. Mix together all ingredients.
Pour into your oven casserole and spread evenly. Drizzle the remaining chili powder on top of the corn. Bake for 35 to 40 minutes.
Remove the casserole from the oven and top your dish with the remaining crumbled Queso Fresco and the dried cilantro. BUEN PROVECHO!
