01 - Preheat oven to 350°F. Grease and line a 9x5 inch loaf pan with parchment paper.
02 - Whisk together all-purpose flour, baking soda, salt, ground ginger, cinnamon, cloves, and nutmeg in a medium bowl.
03 - Beat unsalted butter and packed brown sugar in a large bowl until light and fluffy.
04 - Incorporate eggs one at a time into the butter mixture, mixing thoroughly after each addition.
05 - Stir molasses, whole milk, and vanilla extract into the batter until smooth.
06 - Gradually fold the dry spice mixture into the wet ingredients until just combined; avoid overmixing.
07 - Pour batter into the prepared loaf pan, smooth the surface, and bake for 45 to 55 minutes until a toothpick inserted in the center comes out clean. Cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
08 - Whisk powdered sugar, fresh orange juice, and grated orange zest until smooth and pourable; adjust orange juice quantity for desired consistency.
09 - Drizzle the orange icing over the cooled loaf and allow it to set before slicing.
