Here is a frosting recipe that does not use confectioner's sugar.
4 oz. cream cheese, softened
1/4 C evaporated milk
1/4 C unsweetened cocoa powder
1/3 C honey
1 tsp vanilla extract
1 1/2 C instant nonfat dry milk powder
dash of salt
Soften cream cheese in a bowl at room temperature. Beat cream cheese, evaporated milk, cocoa, honey and vanilla until smooth. Add dry milk powder and a dash of salt. Beat 1 minute more.
Frosting will thicken upon standing.
Thanks!
