Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking pan.
In a bowl, whisk together flour, baking soda, ginger, cinnamon, nutmeg, cloves, and salt.
In a large mixing bowl, cream the softened butter and brown sugar until light and fluffy.
Add molasses and mix well.
Beat in the eggs, one at a time, ensuring each is fully incorporated.
Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Stir in hot water until the batter is smooth.
Pour the batter into the prepared baking pan.
Bake for 40 minutes or until a toothpick inserted in the center comes out clean.
Allow the cake to cool in the pan for 10 minutes before transferring to a wire rack to cool completely.
