I haven’t tried this recipe, but it sounds so yummy! This would make a great holiday recipe.
Mix together 3/4 cup sugar, flour, 3 T cocoa, baking powder, and salt. Add milk, butter, and vanilla. Beat until smooth and pour into ungreased 9 inch square pan. Mix together 1/2 cup sugar, brown sugar, and 4 T cocoa. Sprinkle evenly over the cake batter. Pour the hot water over the batter. Do not stir! Bake for 35 minutes at 350 degrees or until the center is almost set. Let stand for 15 minutes. Serve warm, spooning the sauce in the bottom of the pan over each serving. Top with whipped cream.
