This is my most favorit-est recipe. I substituted applesauce for the oil and buy the caramel sundae syrup. I mix caramel syrup with coconut rum (to taste) and add cool whip to make a drizzle-y soft frosting. I spoon it over the top and let it dribble down the grooves, a capful more of rum along the rim of the plate and a pretty drizzle of caramel only lightly over the top and voila! Always, always a huge hit!
