Preheat the oven to 325℉ and coat an 8 ½ x 4 ½ loaf pan with butter or nonstick cooking spray.
Cream the butter and brown sugar together and stir in the molasses and egg until well blended.
Sift in the flour, baking soda, cinnamon, ginger, nutmeg, cloves, black pepper and salt; stir until well completely combined. Stir in the hot water until the batter is smooth and combined.
Transfer the batter to the prepared baking pan. Bake for 50-55 minutes or until a toothpick inserted in the center comes out clean.
