A very rich cake that tastes almost like a candy bar.
1 Mix and bake cake mix as directed for two 8 or 9 inch layers. Let layers cool then split each one in half horizontally to make a total of 4 layers.
2 In a saucepan over medium heat mix together the white sugar, butter or margarine, and 1/2 cup of the evaporated milk. Cook for 10 minutes. Stir in the marshmallows and mix until smooth. Stir in the coconut. Spread the filling between the cake layers.
3 Mix together the cocoa, remaining 1/4 cup evaporated milk, the confectioner’s sugar, and the vanilla. Beat until smooth and spread over top and sides of cake.
