Preheat oven to 425 F.
Insert wire racks into two baking sheets lined with aluminum foil. (This helps with cleanup.)
Arrange slices out on each baking sheet, spaced closely together.
Liberally sprinkle brown sugar over each slice of bacon, then top with about 3-4 jalapeno slices.
Bake for 15-20 minutes or until desired doneness. (Bacon is thick and may require additional baking for the tray on the bottom rack.)
Allow bacon to cool completely, then store on wax paper in layers and refrigerate until ready to use. (Microwave on a plate, covered with a paper towel for 20 seconds before using.)
