Cake delight!

I had a customer come through my lane a couple days ago, shopping for her grandson's birthday. She said that she had to make his favorite cake, which was this:

except, she makes hers with chocolate cake. I made mine with white because Cody can't have too much chocolate.
Anyways...here's the recipe! It was a major hit!

1 box of chocolate cake mix
1 can sweetened condensed milk
hot chocolate powder
1 container of Cool Whip


Make the cake according to the directions on the box. When finished, let cool for about 10 minutes, then poke holes all over the cake. In a separate bowl, combine your sweetened condensed milk and half-full packet of hot chocolate powder. Spread over the cake. Let stand for about 15 minutes. Spread cool whip over cake and then sprinkle desired amount of hot chocolate powder over the cool whip. ENJOY!
