Sue's No Bake Twinkie Cake Ingredients 1 or 2 Boxes Twinkies (depending on whether you use 9x13 or 9" square pan) 1 Box Cherry Jello (large box if 9x13, small if 9") (Any flavor will work) 1 Container of Cool Whip (or generic) Line bottom of pan with twinkies. Make up the jello as per box instructions. Pour liquid jello evenly over twinkie layer.   Twinkies will absorb the jello. Top with Cool Whip. Refridgerate at least an hour. More if you can keep the kids out of it! Enjoy!
