Title: Jello rainbow cake
 Categories: Cakes
      Yield: 10 servings
 
      1 pk White Cake Mix
      2 pk Jello (3 Oz) Any Flavor
      2 c  Boiling Water
      8 oz Cool Whip, Thawed
 
  Bake cake mix as directed on package.  Remove from pans to cool.
  Rewash pans and put cakes back in them when the cakes are completely
  cooled.  It is best to use 2 8-9" round cake pans but you can use an
  oblong pan if you want.  After cakes have been place back into pans
  (top side up), prick them with utility fork at 1/2" intervals.
  Meanwhile, dissolve each flavor separately in 1 cup boiling water.
  Carefully pour one flavor gelatin over each cake layer (if using
  oblong pan you must use the same flavors for the 2 pks).  Chill 3-4
  hours.  Dip one cake pan in warm water for 10 sseconds, then unmold
  cake layer onto serving plate.  Top with about 1 c. cool whip. Unmold
  second cake layer and carefully place on first layer. Frost with
  remaining topping.  Chill.  Great moist'n fruity cake especially for
  those who like a light, refreshing cake that is not too sweet.
