Make one yellow 9 x 13 inch cake per directions. Dissolve one package lime Jello in hot water. While cake is warm, prick with fork and pour lime Jello over it (goes down through making a pretty green striped cake). Frost with mixture of lemon instant pudding made per box directions and Cool Whip.

Variation: White cake mix with raspberry or other flavor Jello and vanilla pudding with Cool Whip.
