01 - Preheat oven to 350°F. Grease and line a 9x5 inch loaf pan with parchment paper.
02 - Whisk together flour, baking soda, salt, ginger, cinnamon, cloves, and nutmeg in a medium bowl.
03 - Beat butter and brown sugar until light and fluffy using an electric mixer or whisk.
04 - Incorporate eggs one at a time, mixing well after each addition.
05 - Stir in molasses, milk, and vanilla extract until fully combined.
06 - Gradually add dry ingredients to the wet, mixing gently until just combined to avoid overmixing.
07 - Pour batter into the prepared pan and smooth the surface. Bake for 45 to 55 minutes or until a toothpick inserted in the center comes out clean.
08 - Let the loaf cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
09 - Whisk together powdered sugar, orange juice, and orange zest until smooth and pourable; adjust consistency with more juice if needed.
10 - Drizzle the orange icing evenly over the cooled loaf and allow to set before slicing.
