Spread softened butter on the inside of the thick-cut bread. Layer the sharp cheddar cheese between the slices and press down firmly. Slice the sandwiches into thick fingers, then halve them to form small squares.

Wrap one strip of bacon tightly around each grilled cheese square. Push a wooden toothpick directly through the center of each wrapped square to secure the bacon.

Heat a large skillet over medium heat. Place the bacon-wrapped squares seam-side down. Cook for 3 to 4 minutes per side until the bacon is perfectly crispy and glistening.

Watch the edges of your squares. Remove them from the skillet the moment the melted cheddar cheese begins to ooze from the sides.

Drain on a paper towel-lined plate. Stack on a rustic wooden cutting board and sprinkle with finely chopped chives before serving.
