German chocolate layer bars

This is to answer Linz's post about bars. These are pretty rich but very yummy!

1 package caramels
1/3 c. evaporated milk
1 german chocolate cake mix
1 package choc chips
3/4 c. melted butter

Combine caramels and milk in a sauce pan and melt over low heat. Combine remaining ingredients except choc chips in a bowl. Spread 1/2 of this mixture in a 9x13 pan, greased and floured. Bake at 350 for 6 minutes. Remove from oven and sprinkle with chocolate chips then pour caramel over everything. Drop the other 1/2 of the mixture on top of this and bake for 15-20 minutes.
