15.25ouncesboxed chocolate cake mixplus ingredients on the box
14ouncessweetened condensed milk
1cupcaramel sauceplus extra for topping
8ouncesCool Whip
2chopped Heath toffee barsor 10 miniature bars
Instructions
Prepare the cake mix according to package directions. Bake in a 9x13 inch pan as directed on the package.
Meanwhile, combine the sweetened condensed milk and caramel sauce and stir until well incorporated.
When the cake is done, use the handle of a wooden spoon to poke holes all over the cake. Pour the caramel mixture evenly over the top so that it seeps down into the holes. Refrigerate the cake (uncovered) for at least one hour.
Spread the Cool Whip over the top of the cake and sprinkle with the chopped Heath bars.
Notes
Store, covered, in the refrigerator for up to 5 days. It's important to keep the cake chilled because of the whipped topping. Chilling also helps to keep the cake from turning soggy.
