Preheat the oven to 350°F (175°C) and prepare an 8-inch square baking pan by greasing it with butter or lining it with parchment paper.

In a large mixing bowl, whisk together the all-purpose flour, baking powder, ground ginger, ground cinnamon, and ground cloves until evenly combined.

In another bowl, cream together the softened butter and granulated sugar for about 3-4 minutes, then add the molasses and eggs, mixing until fully combined.

Gradually add the dry mixture to the wet ingredients, alternating with the milk, mixing on low speed until just combined.

Pour the batter into the prepared pan and smooth the top with a spatula.

Bake for 30-35 minutes or until a toothpick comes out clean.

Cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
