01 - Preheat the oven to 350°F. Grease and line a 9x5-inch loaf pan with parchment paper.
02 - In a large bowl, whisk together the flour, ground ginger, cinnamon, cloves, nutmeg, baking soda, baking powder, and salt.
03 - In a separate bowl, beat the unsalted butter and brown sugar until light and fluffy. Add eggs one at a time, mixing thoroughly after each addition.
04 - Mix the molasses and vanilla extract into the butter and sugar mixture until fully combined.
05 - Alternately add the dry ingredients and whole milk to the wet mixture, starting and ending with the dry ingredients. Stir gently until just combined.
06 - Pour the batter into the prepared loaf pan and smooth the surface evenly. Bake for 45 to 55 minutes, or until a toothpick inserted into the center comes out clean.
07 - Allow the loaf to cool in the pan for 10 minutes before transferring it to a wire rack to cool completely.
08 - Whisk the powdered sugar with lemon juice and grated lemon zest until smooth and pourable.
09 - Drizzle the lemon icing over the cooled loaf and allow it to set before slicing and serving.
