01 - Preheat oven to 350°F. Grease a 9x5-inch loaf pan and line with parchment paper.
02 - Whisk together the all-purpose flour, ground ginger, cinnamon, cloves, nutmeg, baking soda, and salt in a large bowl.
03 - Beat softened butter and brown sugar until light and fluffy using an electric mixer or whisk.
04 - Add eggs one at a time to the butter mixture, mixing well after each addition.
05 - Stir molasses into the wet mixture until fully combined.
06 - Add dry ingredients in three parts to the wet ingredients, alternating with buttermilk. Begin and end with dry. Mix just until combined to avoid overmixing.
07 - Pour batter into the prepared pan and smooth the surface evenly.
08 - Bake for 35 to 40 minutes until a toothpick inserted in the center comes out clean.
09 - Allow to cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
