Gooey Caramel Brownies

This brownies are awesome, you have to try them.  They are rich & yummy.  Perfect for the holiday season.  A little of this brownie goes a long way, so you can cut them into smaller squares for bite size serving.  Or just go all out like me & eat a big ol' hunk.  The diet starts in January right?!  Might as well pack it in while you still can.  The hardest part about these brownies is the large amount of cooling time they require.  But the actual prep time is minimal.
My husband said these are the best brownies he's ever had.  He says that a lot, "This is the best dinner you've ever made.", "This is the best pasta I've ever had.", etc.  I don't always trust that the item is truly the best he's ever had, a sort of "cry wolf" scenario.  But I do believe him on these brownies.  They are really that good.  Here's the skinny (yes I realize what an oxymoron of a statement that is)...
Ingredients
1 box German Chocolate Cake Mix
1/2 cup finely chopped nuts
1/3 + 1/2 cup evaporated milk (divided)
1/2 cup butter, melted
1 14 oz package whole caramels, unwrapped
1/2 cup chocolate chips
powdered sugar
Directions
Preheat oven to 350 degrees.  Mix together cake mix, chopped nuts, 1/3 cup evaporated milk, & butter.  Stir together until well combined.
Press half of the mixture into a greased 9 x 9 inch baking pan.  Bake for 8 minutes & remove from oven, set aside.
Using the double boiler method melt the caramels & 1/2 cup evaporated milk until smooth & pourable (is that a word?).  Evenly spread caramel sauce over the pre-baked brownies.  Evenly sprinkle chocolate chips on top.  Chill for about 1 hour, or until caramel is hard.
Evenly press remaining  brownie batter on top.  Return to the oven & bake for about 20-25 minutes.  Let cool at room temperature for about 2 hours.  Sprinkle top generously with powdered sugar, cut into pieces, & enjoy!

*In the recipe pictured I did not use the total amount of caramels, because I didn't have 'em & I was too lazy to go to the store.  But there will be a definitive layer of caramel in the center if you use the whole amount listed.
