In a 3-4 quart slow cooker, combine flour, sugar, salt, pepper, water and melted butter with a whisk. Stir in corn.
Cook on high for 3-4 hours or low for 6-8 hours, until hot and the liquid has thickened and becomes creamy. Serve (wasn't that easy?!).
Notes
*If you're gluten free, try swapping out the flour for 2 tablespoons of corn starch and whisking well. *If you're dairy free, try swapping out the butter for dairy free margarine.
