better than XXX cake

in honor of valentines day, I wanted to share this recipe with you.  my friend jen made this cake one time and I was hooked; rich chocolate cake, caramel, toffee, and whipped topping - need I say more?!

1 (18.25 ounce) package devil's food cake mix
1/2 (14 ounce) can sweetened condensed milk
6 ounces caramel ice cream topping
3 (1.4 ounce) bars chocolate covered toffee, chopped
1 (8 ounce) container frozen whipped topping, thawed

1. bake cake in a 9 X 13 inch dish, according to package directions; cool on wire rack for 5 minutes.  using a toothpick, poke holes in the top of the cake, making sure not to go through to the bottom.
2. in a saucepan over low heat, combine sweetened condensed milk and caramel topping, stirring until smooth and blended.  slowly pour the warm topping mixture over the top of the warm cake, letting it sink into the holes; then sprinkle the crushed chocolate toffee bars liberally across the entire cake while still warm.
3. let cake cool completely, then top with whipped topping.  decorate the top of the cake with some more chocolate toffee bar chunks and swirls of caramel topping.  refrigerate and serve right from the pan!
