Butter one side of each slice of bread while skillet or grill gets hot. About 325-350F.
Lay bread butter side down on hot skillet, stack on cheese and top with other slice of bread with butter on top.
Let grill till bottom is golden brown then flip over and do the other side. You have the option to mash or not to mash. My opinion is a good grilled cheese sandwich should be mashed flat with the spatula.
Check both sides for color and be sure cheese is melted before eating.
