In a medium sized mixing bowl, combine the flour, baking powder, salt, sugar and cocoa.  Then stir in the melted butter, milk and vanilla.

Step 3

Spread the mixture into a greased 1.5 qt casserole dish (or square pan).  Set aside.

Step 4

In another bowl, combine the dry topping ingredients (sugar, brown sugar, salt and cocoa).  Sprinkle on top of the batter; do not stir.

Step 5

Pour the boiling water on top; do not stir.
