Hot Fudge Sundae Cake

1 C. all purpose flour
3/4 C. white sugar
2 T. baking cocoa
2 t. baking powder
1/4 t. salt

1/2 C. milk
2 T. vegetable oil
1 t. vanilla
1 C. chopped nuts (optional)

1 C. brown sugar, packed
1/4 C. baking cocoa
1 3/4 C. very hot water

Preheat oven to 350.
In an ungreased 8x8 square baking dish, using a fork, mix the first set of dry ingredients well.
Stir in the milk, vegetable oil, and vanilla; mix until smooth.
If adding nuts, do that now.
Spread the batter evenly in the pan.
Sprinkle the brown sugar, then the cocoa, evenly on top of the batter. Pour the hot water over the top; DO NOT MIX.

Bake for 40 minutes until the top layer has a dry, brownie-like top.
