1. Bake the cake per the box instructions in a Bundt pan. Place the cake on a large platter.

2. When the cake is done and while still hot, poke holes with a fork.

3. Pour sweetened condensed milk over the hot cake – it will soak in. Cool.

4. Pour caramel topping over top of cake and spread whipped chocolate frosting over the top. Sprinkle with the crushed Heath bars and the crushed walnuts if using.
