Place a chocolate kiss in the center of a wonton wrapper. (Keep remaining wrappers covered with a damp paper towel until ready to use.) Moisten edges with water; fold opposite corners together over candy kiss and press to seal. Repeat.
In an electric skillet, heat 1 in. of oil to 375°. Fry wontons for 2-1/2 minutes or until golden brown, turning once. Drain on paper towels. Dust with confectioners' sugar.
