Preheat oven to 350 degree Fahrenheit.
In a large bowl, place the softened cream cheese.
Using a fork, you can break the softened cheese very well and then mix well using a spoon.
Also add the milk and melted butter, mix well using a spoon to form a mixture. If some of the cream cheese mixture is not smooth, it is totally fine. You just need to mix the ingredients together, it doesn't have to form a very smooth mixture.
Add salt and one teaspoon of black pepper, mix well to combine.
Add the frozen corn kernels and also the ½ cup of shredded cheese, mix well to combine evenly with the cream cheese mixture.
Prepare a casserole or baking pan (8 by 8 square pan works well) by greasing with a little olive oil, and transfer the prepared corn cream cheese mixture to the baking pan.
You can use a spoon to press the mixture gently to the pan so it is evenly spread.
Place the baking pan in the preheated oven and bake for about 25 minutes.
Once this is baked, carefully take the pan out and add the one cup of shredded cheese on the top evenly across the pan. Also sprinkle the one teaspoon of black pepper for topping, evenly (if you are using it).
Increase the oven temperature to 400 degree Fahrenheit.
Place the baking pan back in the oven and bake for another 10 minutes so the cheese is melted and slightly golden brown in color!
Once the baking is done, immediately transfer the corn casserole from the hot oven, allow it to cool down slightly, enjoy it as a delicious cheesy corn side dish with dinner, lunch or any holiday meal or everyday meal as you like!
