01 - Preheat a nonstick skillet or griddle over medium heat until evenly warmed.
02 - Spread 1/2 tablespoon of softened butter on one side of each waffle, ensuring even coverage to promote golden browning.
03 - Place 2 waffles on a cutting board with the buttered side facing down. These will form the bottom of your sandwiches.
04 - Spread 1 tablespoon of fruit preserves evenly over the unbuttered side of each base waffle, leaving a small border around the edges.
05 - Arrange 2 slices of cheese over the preserves on each waffle, ensuring complete coverage for even melting.
06 - Place the remaining waffles on top, buttered side facing up, to form two complete sandwiches.
07 - Carefully transfer the sandwiches to the preheated skillet. Cook for 3 to 4 minutes per side, pressing gently with a spatula, until the waffles achieve a deep golden color and the cheese is completely melted.
08 - Remove from heat and slice each sandwich in half. Serve immediately while the cheese remains warm and gooey.
