Well grease a 9x13" cake pan and set aside. (I use the non-stick spray from Costco.) For extra easy clean up, you can line the pan with parchment paper.
Stir together cake mix, 1/3 cup of evaporated milk, and melted butter in a mixing bowl till smooth. Spread half of batter into your prepared pan and bake at 350° for about 6 minutes.
Meanwhile, melt caramels and 1/3 cup evaporated milk in a glass bowl in the microwave, stirring often.
Remove brownies from the oven and sprinkle the chocolate chips and chopped pecans over top. Pour the caramel evenly over everything.
Top with remaining dough. I take pieces of the dough and flatten them in my hands (kinda like play-doh) and place them over the top. It’s okay if you have small gaps.
Bake for 18-20 more minutes or until a toothpick inserted just in the top layer comes out with moist crumbs, not batter.
For easiest cutting, cool completely.
Notes
While brownies are still warm, go around the edge of the pan with a knife or metal spatula to pull the caramel away from the sides.
These are really rich, so cut them into small pieces.
