GF Heath Bar Cake

1 box GF chocolate cake mix (I use Betty Crocker)
1 stick of butter softened
3 eggs
1 cup of water
1 can sweetened condensed milk
1 jar caramel dessert topping (Smucker's is GF)
1 8 oz container whipped topping
1 bag snack sized Heath Bar candy

1. Prepare cake according to directions on box.
2. Immediately upon removing cake from oven poke holes over entire cake.  This will help the condensed milk mixture to absorb well into the cake.
3. Combine condensed milk and caramel topping in small sauce pan. Heat until well blended. Pour immediately over top of cake. I like to allow my cake to soak overnight. After the cake has cooled you can cover with foil or plastic wrap and refrigerate until morning.
4. Unwrap Heath candies and place into plastic bag. Smash until broke into small pieces.
5. Layer cake with a portion of smashed Heath candies.
6. Layer with entire whipped topping
7. Layer with remaining smashed Heath candies.

This cake is VERY rich, enjoy in small portions :-)
