Directions In a small bowl, mix confectioners' sugar and 1 to 2 teaspoons water until a smooth but thick glaze forms (too thin a glaze will be absorbed by the cake). Place a piece of waxed paper under cooling rack for easy cleanup. Spoon glaze back and forth over cake, forming a pattern. Keep cake on cooling rack until glaze is set, 15 to 20 minutes.
