1/4 cup butter
1 3/4 cups sugar, divided
1/4 cup plus 1 1/2 tablespoons cocoa, divided
1/2 cup milk
1 cup self-rising flour
2 teaspoons vanilla
1 cup water

Melt butter in a 1 1/2 -quart casserole dish in a 350-degree oven. Meanwhile, in a mixing bowl, combine 3/4 cup sugar, 1 1/2 tablespoons cocoa, milk, flour and one teaspoon vanilla flavoring.
In a separate bowl, mix 1 cup sugar, 1/4 cup cocoa, remaining teaspoon vanilla and water.
Pour flour mixture into heated casserole over melted butter. Top with water mixture — do not stir! Bake at 350 degrees for 30 minutes. The cake makes its own sauce as it bakes.
