Cool Lemon-lime Sheet Cake

• 1 lemon cake mix (size package to make a regular layer cake)
• egg, as required by the mix
• oil, as required by the mix
• 1 package lime Jell-O gelatin (size package to serve 4)
• 1 cup boiling water
• 12 cup cold water
• 1 package lemon pudding mix (the kind that you mix with milk and doesn't need cooking, should be a size package to serve 4)
• 1 package Dream Whip (do not premix, should be the type that makes 2 cups) or 1 packet similar whipped dessert topping mix (do not premix, should be the type that makes 2 cups)
• 2 cups milk

1. Bake the lemon cake mix as per instructions in a 13" x 9" pan.
2. Cool.
3. While cooling, mix the lime jello with the boiling water to dissolve completely, then add the cool water.
4. Cool jello but do not allow mixture to get too thickened before doing the next step.
5. It has to be able to pour easily.
6. Make holes in the cake 1" apart over the whole surface (yes all the way to the bottom of the pan!
7. ).
8. I use the handle of a wooden spoon, round and maybe 1/4" in diameter.
9. Pour the lime jello into the holes with a teaspoon.
10. Use all the jello, even if you have to do the holes more than once.
11. Cover with plastic wrap and refrigerate until cold.
12. Beat the dry lemon pudding mix, dry whipped topping mix and milk with an electric mixer (on high after the ingredients are blended) until light and fluffy.
13. Frost the cake and refrigerate until ready to serve.
