Preheat the oven to 350°F/180°C or 160°C fan oven, and grease a 9x13 inch (approx. 23×33 cm) pan with baking spray. Set aside.
In a bowl, combine the flour with baking soda, baking powder, ginger, cinnamon, cloves, nutmeg, and salt. Set aside.
In a bowl of a stand mixer or in a bowl with a hand mixer, cream the butter and sugar for one minute or until creamy. Then add the eggs and vanilla extract and beat again for another minute scraping down the sides of the bowl, until well combined.
In a small bowl, combine the molasses with hot water. Add the dry ingredients and the molasses mixture to the bowl with the butter, and mix at low speed until just combined.
Pour cake batter into the prepared pan. Bake in the preheated oven for 20-25 minutes or until a toothpick comes out clean from the center of the cake or a few crumbs remain.
Remove from the oven, and allow to cool on a wire rack.
