The recipe is here:
3 cups graham cracker crumbs*
1-2 sticks butter or margarine*
1 package each Jell-O Orange, Cherry, and Lime Gelatins (sugar-free also works)
3 cups boiling water
2 cups cold water
2 packages Jell-O Lemon Gelatin (sugar-free also works)
2 cups boiling water
1 1/2 cups cold water
1 tub Cool Whip (regular or sugar-free only)**
(*) Or use 16 to 18 ladyfingers, split, to line pan instead of crumb-butter mixture.
2nd Day before Serving:
Prepare the three flavors of gelatin separately, using 1 cup boiling water and 1/2 cup cold water for each. Pour each flavor into an 8-inch square pan. Chill until firm, or overnight.
Prepare crust by grinding graham crackers and mixing with butter using a pastry cutter. Line bottom of 10" spring form cake pan with wax paper before pressing crumb mixture all over interior of pan. Place in fridge overnight.
Day before Serving:
Prepare lemon gelatin using the 2 cups boiling water and 1.5 cups cold water (you may want to prepare in two batches to expedite cooling process). Place in fridge. When it achieves a syrupy texture (running a spoon through leaves a trail), it is ready to be combined with the Cool Whip. Blend Cool Whip with lemon gelatin, reserving 2 cups to finish the top.
Cut the firm gelatins into 1/2-inch cubes. Fold into larger quantity of lemon mixture. Pour into pan and add remaining lemon mixture on top to finish. Chill overnight.
Untape wax paper on bottom and spread before unmolding. Run knife or spatula between sides of dessert and pan, remove sides of pan, and slide cake carefully onto serving plate. If desired, spread additional prepared whipped topping or whipped cream on top and sides. Makes 16 servings.
NOTE: Other Jell-O Gelatin fruit flavors may be used instead of those suggested in recipe, forming any combination of colors desired. For instance, make all the cubes of Jell-O Black Raspberry or Lime Gelatin and substitute Jell-O Strawberry Gelatin for the lemon gelatin.
* Soft ladyfingers can be used instead of a graham cracker crust. You will need about 2 dozen
** Do not use fat free or reduced fat Cool Whip; it will not set.
