Chocolate Pudding Cake

I found the recipe here.

Ingredients
1 box cake mix (yellow, white, chocolate) (I used a half box of cake mix)
Cool whip (I used about 1 1/2 cups)
2 boxes of chocolate pudding mix (I used one box)

Directions
Bake the cake as directed on the box. (I only made half the cake).
Once it is cooked, poke holes in the cake with the end of a wooden spoon while the cake is still hot. Pour half of the chocolate pudding mix(before the pudding cools or sets up) onto the cake so that it soaks into the holes.
Then put the rest of the pudding in the fridge to set up. Once it is set up, add the cool whip and mix them together. Then frost the cake with the pudding/cool whip mix.
Put the cake in the fridge to cool.
