01 - Spread softened butter evenly on one side of each bread slice, ensuring complete coverage to the edges.
02 - Place two bread slices buttered side down on a clean surface. Layer two cheese slices on each piece, then top with remaining bread slices, buttered side up.
03 - Preheat a large skillet or griddle over medium heat for 2-3 minutes until evenly heated.
04 - Place assembled sandwiches in the hot pan. Cook for 3-4 minutes, pressing gently with a spatula, until the bottom is golden brown and crispy.
05 - Carefully flip sandwiches and cook the second side for 3-4 minutes until golden brown and cheese is completely melted.
