Mix all dry ingredients (including candied ginger) together and set aside. Stir molasses into ½ cup of boiling water mixture and set aside.

Mix butter and ¼ cup brown sugar until fluffy, then beat in egg until smooth. Add half the reserved flour mixture to the butter mixture and stir until just mixed. Stir in molasses/water mixture. Add remaining flour mixture and stir until all dry ingredients are incorporated.

Pour into greased baking dish (8-9”) and sprinkle remaining brown sugar over top.

Finally, whisk remaining ¾ cup boiling water with reserved 2 tablespoons butter. Pour over batter in pan, but do not stir! Bake for 30-35 minutes at 350 degrees until the top is cracked, set, and slightly spongy feeling when pressed lightly. Cool and serve warm with your choice of topping!
