Caramel Brownies

This recipe originally called for a box of chocolate cake mix. I tried using a gluten free version of boxed cake mix and the result was a disaster! Rarely do I have to throw food away and start over, but that time I did. Since I had already melted the caramels in the microwave, I quickly scoured the internet looking for the perfect made-from-scratch cake mix substitute. I tweaked a few of the ingredients and these brownies turned out to be the best I had ever made!

Caramel layer:
 11-oz package caramel bits plus 1/2 cup from another 11-oz package
 1/3 cup evaporated milk
