This cake is usually known as the "Better than sex cake" But also has lots of other names and lots of different versions, this was how I made mine.
1 box devils food cake mix
heath candy bars
chocolate cool whip
Bake cake according to directions (I did add some of the toffee bits to the cake batter), let cool for a few minutes. Poke holes with fork all over the cake. Drizzle caramel topping over top (to your desired liking) so it starts to melt into the cake. Then I put it in the fridge to finish cooling.
Add cool whip to top of cake and top with heath toffee bits.
Oh so delicious!!
* I grabbed the bag of Heath Toffee pieces from the baking isle, and when i got home realized it only was the toffe bits, so I took about 1 cup of semi sweet chocolate chips and chopped those up and added it to the toffee pieces.
