on cake while hot. Sprinkle with additional coarsely, chopped nuts, if desired. Let cool; frost. FROSTING: Mix frosting ingredients with enough hot water to mix well. Spread frosting mixture over cake. Sprinkle top with more nuts, if desired. If kept refrigerated, cake will be fudge-like, or very moist when kept at room temperature. For an extra treat, zap a refrigerated piece in the microwave; top with a scoop of vanilla ice cream. ----
