I changed up this recipe for a work pot luck just a tad. It was a St. Patrick's Day pot luck, so I used lime jello, and I made it in a 13x9 dish, so just one layer. I also added 6 drops of green food color to the cool whip to make a green frosting. Green sprinkles on top -- and voila! Best dessert of the pot luck. Thanks for posting this! I'm going to try it your way this summer, for sure.
I know this is a good recipe, and it sure brings back memories. I used to make this when my kids were little, the only thing different was that I made it as a sheet cake with one flavor of jello. Not too long ago I found a recipe which was very like this one,except after mixing up the cake, you divide the cake batter into seprate bowls and add a box of sugar free jello to each one, then bake and frost with cool whip.
