I make a jello cake just like this all the time. My step-mother taught me, and its so easy but so good. The only difference between the cake I make and this is the icing. We take the Cool Whip and put it in a big mixing bowl and fold in a package of pudding. We usually use a white cake and flavor it with the jello/pudding combo. For instance we would use lime jello with lemon pudding, strawberry jello with banana pudding, or my favorite is raspberry jello with white chocolate pudding.
