Mix together cake mix as directed on the box adding the eggs, water, and vegetable oil. Pour half of the batter into a greased 9x13 baking dish and bake at 350℉ for 20 minutes.
While it bakes, unwrap all the caramels (don't have your husband help- he will eat half of them. I am totally speaking from experience). Put the caramels, milk, and butter in a sauce pan and melt over low heat, stirring constantly until caramel is melted and smooth.
Pour the caramel on the cake as soon as it is finished baking. Sprinkle the chocolate chips and pecans on top of the caramel. Spread the remaining half of the prepared cake mix batter on top. Bake for 20 more minutes at 350 degrees.
If desired, serve topped with ice cream and hot fudge.
Notes
We recommend refrigerating this cake and keeping it in a container, or tightly wrapped up with saran wrap or foil, for the best results. It will be good in the fridge for about 3 days, but recommended you eat the day of making it.
