Peel caramels and place in a microwave-safe bowl. Stir in 1/2 cup evaporated milk. Heat and stir until all caramels are melted (you can also do this on the stove-top over low heat- just keep stirring until caramels are melted).
Preheat oven to 350 degrees F (175 degrees C) Grease a 9x13 inch pan (and when I say grease it, I mean it! These tend to be sticky, so grease it well. You may also want to grease the sides of the pan to prevent the caramel from sticking).
In a large mixing bowl, mix together cake mix, 1/3 cup evaporated milk, melted butter, and chopped pecans. The dough will be VERY thick and kind of hard to stir- that means that you made it right! Place 1/2 of the batter in prepared baking pan. I sprayed my fingers with non-stick cooking spray and spread it in the bottom of the pan using my hands.
Bake for 8 minutes.
Place the remaining batter into the fridge. Remove brownies from oven and sprinkle chocolate chips on top. Drizzle caramel sauce over chocolate chips. Remove brownie mix from refrigerator. Using a teaspoon, make small balls with the batter and smash flat. Very carefully, place on top of the caramel sauce until the top is completely covered. With the batter being so thick, I places little teaspoonfuls all over the top and then carefully pushed them together to cover the caramel. It doesn't look very pretty, but they will still taste amazing. 🙂
Bake for an additional 15-20 minutes. Remove and let cool. It is best to wait until the brownies are cooled to cut into them (it will be hard, but trust me- they are so worth the wait!).
