Chocolate-Marshmallow Frosting Recipe

Combine chocolate and butter in top of double boiler; bring water to a boil. Reduce heat to low; cook, stirring constantly until chocolate melts. Cool. Combine sugar, egg, vanilla and chocolate mixture in med. bowl; beat with electric mixer until smooth. Stir in marshmallows and pecans. This makes enough for a 9 inch square pan.
