Heat a grill pan over medium heat. Butter ½ teaspoon on one side of each waffle.
Place buttered side down onto hot grill pan. Place a tablespoon of apple butter onto each waffle, layer bacon over butter and then top with cheese slices (about 3 slivers).
Next place remaining waffle and butter the tops.
Cook sandwiches for about 4 minutes per side or until toasted and cheese has melted.
