For another fun idea to add a little jazz to this recipe, you can add some Jell-O instant pudding the the layers. Just put it in between the Strawberry Jello and the Whipped Topping. Simple make the Pudding according to the directions on the box, let it set and cool, then spread it on top of the Strawberry Jello before you add your whipped topping. I'd suggest using Vanilla Pudding flavor, but you can use any flavor that sounds awesome to you!
One of the keys to this recipe is that you need to let everything cool and set if it says to do so in the instructions. So, while this IS a simple recipe to make, it is not a QUICK recipe. So, make sure allot plenty of time to prepare this recipe. It's not a bad idea to make the cake the day before to make sure it has time to fully cool before adding the toppings.
