1 c. white sugar
1/4 c. butter
1/4 c. milk
1/2 c. chocolate chips
1 handful miniature marshmallows
1 tsp. vanilla

Combine sugar, butter and milk in saucepan. Bring to a boil. Boil 1 1/2 minutes no longer. Remove from heat. Add chocolate chips, marshmallows and vanilla. Mix well and let set until thick enough to spread. This will frost a 9 x 13 inch cake.
