Better than Sex Cake

I believe my aunt Tookie is the woman responsible for the name. All claims aside, this is a damn good cake, and it's SUPER easy to make.

Ingredients
-1 chocolate cake mix + ingredients for cake (eggs, water, oil)
-1 can sweetened condensed milk
-1 jar butterscotch ice cream topping
-1 package CoolWhip (thawed in fridge)
-2 Butterfingers

Steps
1. Make cake as directed.
2. As soon as cake comes out of oven, poke a bunch of holes (like every centimeter) in the cake (I use the back of a wooden spoon).
3. Immediately pour condensed milk and butterscotch topping into holes and over cake.
4. Let cake cool completely.
5. Top with whipped cream and crushed up Butterfingers.
(Note: I let the CoolWhip dethaw in the fridge for several hours so that it is spreadable)
