I've made this recipe for my family for over 40 years. It's an old time favorite. It's easy to make and goes great with ice cream or whipped topping. Best if it's warm. If you feel guilty about chocolate, you can substitute cocoa with Carob powder, it's a natural ingredient and still tastes awesome.
Mix until well blended with a spoon - flour, white sugar, cocoa, baking powder, salt, milk, vanilla, and salad oil in a bowl. Spray an 8 X 8 inch baking dish, pour this batter into the baking dish.
Mix Brown sugar and cocoa and sprinkle dry on top of batter in baking dish. Gently pour hot water over the top. Bake at 350 degrees for about 35-40 minutes. remove from oven, let cool for about 20 minutes. This recipe makes it's own sauce. Serve with ice cream or whipped topping. It's a great crowd pleaser.
