Chocolate Mocha Icing

1/2 c Margarine
2 ts Instant coffee
1/4 ts Salt
1/2 c Cocoa
1 ts Vanilla
1 Egg
1/3 c Milk
4 c Icing sugar Beat to-gether with mixer the egg, salt, cocoa and coffee. Alternately add the milk and icing sugar and vanilla. This makes light, fluffy and extremely sweet icing and is fool proof.
