Arrange the bacon strips on a broiler pan.
Combine brown sugar and cayenne pepper in a bowl and set aside.
Warm up the grill to around 300-350 degrees.
Place the broiler pan with the bacon on the grill and cook for about 15 minutes, then flip the bacon.
Lavishly coat the bacon with the brown sugar mixture and cook for another 15 minutes.
Coat the bacon with the maple syrup on both sides and cook for another 5-10 minutes, depending on how crispy you like it.
Remove from grill, let cool, then serve.
