Spread each side of the sandwich bread with the soft butter.
Heat a skillet over medium heat and place 2 slices of bread in the skillet. Place the cheese on one piece of toast and top with basil leaves. Close the slice of bread with another bread slice.
Cook the sandwich until both sides are golden brown and the cheese is melted. This should take about 5 minutes. Repeat with the other Sandwich bread.
Remove the Sandwiches from the skillet and transfer to a cutting board. Cut the sandwiches in half and serve warm!
