Chocolate Marshmallow Log Candies

Spread 1 cup coconut on each of four 16-by-12-inch pieces of waxed paper; set aside.

Heat chocolate chips and butter in a large saucepan over low heat until melted, stirring constantly. Remove from heat; let stand for 10 minutes. Stir in egg product; combine well. Stir in marshmallows and walnuts, coating well with chocolate mixture. 

Spoon one-fourth of the mixture onto each piece of waxed paper. Using your hands, form mixture into a 12-inch log, coating well with coconut. If necessary, sprinkle additional coconut over log to cover evenly. Roll log in waxed paper and twist ends closed. Chill in refrigerator for 2 to 24 hours. Slice each log into ½-inch pieces.  Store candies in the refrigerator for up to 1 week.
