Preheat oven to 375°F. Line a rimmed baking sheet with foil, and place wire rack on tray.
Arrange bacon slices in a single layer on wire rack. Sprinkle each slice with about 2 tablespoons of brown sugar. Add black pepper, and sprinkle with cayenne pepper.
Bake bacon for 22-25 minutes or until dark and crisp (bacon won't be firm yet). Remove from oven, and cool on rack for 5-7 minutes or until sugar has hardened.
Notes
When placing bacon on wire rack, place it the opposite direction of the slits so it doesn't fall through while cooking.
