I think this is called Holy Cow Cake because that's what everyone says when that taste it =)
Note...cool whip and cream cheese topping is kinda rich. I have replaced the cream cheese with a small pack of jello vanilla pudding mixed with the cool whip and it isnt as rich.
While cake is still warm poke holes with a straw or chopsticks.
mix about 4oz of carmel topping with the condensed milk and spoon slowly over the warm cake making sure the mixture seeps into the cake.measure about 1/2 of the candy bar mixture and sprinkle on the cake.
Mix cool whip and cream cheese with an electric mixer until smooth.Spread mixture on top of cool cake. Sprinkle remaing candy bar.Drizzle caramel and chocolate ontop if desired.
Place cake uncovered in refrigerator to chill for about 20 minutes before serving. Store covered in refrigrator.
