Heavenly Caramel Brownies

1 Devil's Food Cake Mix
1 (8 oz) pkg caramels
3/4 C melted margerine
2/3 C evaporated milk
1 C chopped pecans (optional)
1 C semi-sweet chocolate chips

Preheat oven to 350. Melt caramels with 1/3 C evaporated milk. Combine cake mix with melted butter and the remaining 1/3 C evaporated milk. Spread half of the cake mixture in a greased 9x13 pan, and bake for 6 minutes. Remove from oven and sprinkle with chocolate chips, then spread caramel on top. (If you're using pecans, sprinkle on top of the caramel.) Then, crumble remaining cake mixture over the top. (It will spread out while it's baking, so don't worry about it not covering the caramel completely!) Bake for 18 minutes. ENJOY!
