Methods:

1.Preheat the oven to 350 degrees. Grease an 8, inch square baking pan.
2.Cream together the butter and the 1/2 cup of brown sugar in a mixing bowl. Add the eggs and vanilla and mix until blended. In a small bowl, mix together the flour, salt, baking soda, and the 1/3 cup cocoa. Add the flour mixture to the butter mixture and blend. Stir in the 2 tablespoons water. Pour the batter into the baking pan. Mix together the remaining 1/3 cup brown sugar, 1 tablespoon cocoa, and the 1/3 cup hot water. Pour the hot water mixture over the batter.
3.Place the pan in a slightly larger ovenproof dish. Add 1 inch of boiling water to the larger dish and put into the oven. Bake for 20 to 25 minutes, or until a skewer comes out clean. Dust with confectioners' sugar. Serve with lightly whipped cream.
