Preheat the oven to 350°F.
Spray an 8x8-inch baking dish with nonstick cooking spray.
In a small bowl or measuring cup, combine the water and unsulphured molasses.
Stir until the molasses is fully dissolved and evenly blended into the water. Set aside.
In a large mixing bowl, add the all-purpose flour, granulated sugar, baking powder, baking soda, cinnamon, ginger, cloves, and salt.
Whisk or stir the dry ingredients until evenly combined.
Make 3 depressions in the dry ingredient mixture: 2 small depressions and 1 larger depression.
Add the vanilla extract to one small depression.
Add the apple cider vinegar or white vinegar to the second small depression.
Add the canola oil or vegetable oil to the larger depression.
Pour the prepared water and molasses mixture evenly over the dry ingredients and wet ingredients.
Stir gently until the batter is smooth and fully combined.
Do not overmix the batter, as excessive mixing may affect the texture of the cake.
Pour the batter into the prepared 8x8-inch baking dish.
Spread the batter evenly in the dish with a spatula, if needed.
Place the baking dish on the middle rack of the oven.
Bake for approximately 35 minutes, or until a toothpick inserted into the center of the cake comes out clean or with a few moist crumbs.
If wet batter remains on the toothpick, continue baking for a few additional minutes and check again.
Remove the cake from the oven.
Allow the cake to cool in the pan before slicing and serving.
Serve plain, or finish with powdered sugar, frosting, whipped cream, caramel sauce, lemon sauce, or another preferred topping.
