Cheesy Corn

We had a reunion this past Sunday & one of our family members brought this. It was delicious but Dustin thinks its the best thing EVER so we had to get the recipe. I was given the ingredients but Im still unsure if you throw it all in the crockpot and stir at the end or if you mix some of it before putting it into the crockpot? Anyways here it is...

22oz Frozen Corn
11oz Cream Cheese
1 Stick Butter
2 Tbs. milk
2 Tbs. water
2.5 Tbs. sugar
8-10 slices American Cheese

Cook on low for 4 hours.
