Graveyard Cake

Directions

1. In a bowl, combine flour, sugar, baking soda and salt; set aside. In a saucepan, combine butter, water and cocoa; bring to a boil over medium heat. Add to flour mixture; beat well. Beat in sour cream and eggs.
2. Pour into a greased 13x9-in. baking pan. Bake at 350° for 35-38 minutes or until a toothpick inserted in the center comes out clean. Cool on a wire rack for 5 minutes.
3. Meanwhile, in a saucepan, combine butter, milk and cocoa; bring to a boil. Remove from the heat; stir in sugar and vanilla. Pour over warm cake. Crumble chocolate cookies; sprinkle over frosting while still warm. Cool completely.
4. For tombstone, use icing to decorate vanilla cookies with words or faces; place on cake. For ghosts, make mounds of whipped topping; use icing to add eyes and mouths as desired. Refrigerate for at least 1 hour. Just before serving, add pumpkins and gummy worms if desired.
