1 dark chocolate cake mix (plus oil, eggs & water as directed)
1 teaspoon vanilla extract
Filling
1 cup granulated sugar
1 cup milk
15 regular-sized marshmallows
1 teaspoon vanilla
12 oz. sweetened coconut flakes
Frosting
1/2 cup butter
2/3 cup evaporated milk
2 cups granulated sugar
6 oz. semi-sweet chocolate morsels
Instructions
Combine the ingredients for the cake mix, adding a teaspoon of vanilla extract. Pour batter into three greased and floured 9-inch baking pans. The layers will be thin.
Bake at 350ยบ for 15-20 minutes or until a toothpick inserted near the center comes out clean. Let cool in pans for ten minutes. Remove from pans and cool completely on wire racks.
Make the filling by combining sugar and milk in a saucepan and bring to a boil. Add vanilla, coconut, and marshmallows and boil over medium heat for five minutes. Let cool slightly and spread between cake layers.
Combine the frosting ingredients (butter, evaporated milk, 2 cups sugar, and semi-sweet morsels) in a saucepan. Bring to a boil and boil for 2 minutes, stirring constantly. Remove from heat and cool until spreading consistency. The frosting will harden as it cools. Frost top and sides of the cake.
