Method to the marvelous choco madness:
Mix together dry ingredients for cake. Add oil, vanilla, vinegar and water, mixing until blended. Pour into 13×9 pan and bake at 350 degrees for 35-40 minutes. Cool. Once cake is cool, poke a few holes in it. Pour caramel sauce over cake. Frost the cake with Cool Whip. Sprinkle crushed candy bar over Cool Whip. Best served same day. Refrigerate leftover cake.
Hmmm, thinking a grocery store run is needed!
