Melt caramels with 1/3 cup of evaporated milk in microwave on high for about two minutes.
In a mixing bowl, combine the cake mix, melted butter, and 1/3 cup of evaporated milk and mix well. Add nuts and mix again. Spread half of the dough into a greased 9x13 pan. Bake at 350 degrees for 10 minutes.
Remove from oven. Sprinkle chocolate chips over the baked crust. Drizzle caramel mixture atop. With hands, form remaining dough into a small pancakes and place over the caramel mixture. Will NOT cover completely. Bake for 20 minutes. Cool slightly before cutting.
Please note that I use Kraft brand caramels and they currently are packaged in an 11 ounce bag so I purchase TWO bags and use 50 total caramels to yield approx. the 14 ounces the recipe calls for.
