Preheat oven to 350°F. Line two cupcake tins with paper liners (24 cupcakes). Set aside.
In a medium bowl, combine flour, baking powder, ginger, cinnamon, nutmeg, cloves, and salt. Whisk together and set aside.
In a small bowl or pyrex jug, add the baking soda to the hot water and mix. Set aside.
Using a stand mixer with the paddle attachment (or a handheld electric mix and a large bowl), cream the brown sugar, butter and vegetable oil until light and fluffy.
Add molasses and mix until well combined.
On low speed, alternate adding the water/baking soda mix and the dry Ingredients. Start by adding about ⅓ of the water, then ⅓ of the flour, and so on until everything is combined.
Increase speed to medium and add the eggs, one at a time. Mix until well combined.
Fill each cupcake liner about halfway (approximately ¼ cup worth of batter).
Place In the middle rack of the preheated oven and bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean.
