Preheat your oven to 180°C (350°F). Grease or line your 8x8-inch square pan with parchment paper.

In a large mixing bowl, combine the flour, baking soda, baking powder, ground ginger, cinnamon, cloves, and salt.

In a separate bowl, whisk the melted butter, brown sugar, egg, and molasses until smooth.

Gradually add warm water to the wet ingredients and mix well.

Pour the wet mixture into the dry ingredients and stir gently until just combined. If using, fold in the fresh grated ginger.

Transfer the batter into the prepared pan and smooth the top.

Bake in your preheated oven for 35–40 minutes, or until a toothpick inserted in the center comes out clean.

Let the ginger bread cool in the pan for about 10 minutes before transferring it to a wire rack.

Optionally, serve warm or dust with powdered sugar before serving.
