Better Than Sex or Roller Coaster Cake

1 box devils food cake mix
1 box chocolate pudding
1 box butterscotch pudding 
Eggs
Oil
1 tub cool whip
Crushed health candies
I jar of caramel sauce
Chocolate syrup

Preheat oven according to box mix directions. Prep cake pan. Combine box mix and chocolate pudding mix. Add eggs, oil, and water according to box directions. Bake. After cake is done but still warm prick with a fork. Pour half the caramel sauce(warmed in a microwave) over cake. Cool cake.
Frosting:
Make pudding with 1 3/4 cup milk rather than 2 cups. Set in fridge for 45 minutes to thicken. Fold cool whip into pudding. Frost cake. Top with drizzles of caramel , chocolate syrup,& crushed health bar!

*Assuming you already have eggs and oil, the ingredients roughly cost me $10, would serve 12 depending on slices.*
